CVE reference:CVE-2006-2693


Description:
Mustafa Can Bjorn has discovered a vulnerability in the Nivisec Hacks List module for phpBB, which can be exploited by malicious people to disclose sensitive information.

Input passed to the "phpEx" parameter in admin_hacks_list.php isn't properly verified, before it is used to include files. This can be exploited to include arbitrary files from local resources.

Example:
http://[host]/admin/admin_hacks_list.php?setmodules=1&board_config[default_lang]=english&phpEx=[file]

Successful exploitation requires that "register_globals" is enabled.

The vulnerability has been confirmed in version 1.20. Other versions may also be affected.

Solution:
Edit the source code to ensure that input is properly sanitised.

Set "register_globals" to "Off".
