http://secunia.com/advisories/30304/

CRITICAL:
Moderately critical

IMPACT:
Exposure of system information, Exposure of sensitive information

WHERE:
>From remote

SOFTWARE:
Forum Rank System 1.x (module for PHP-Fusion)
http://secunia.com/product/18732/

DESCRIPTION:
Matrix86 has reported two vulnerabilities in the Forum Rank System
module for PHP-Fusion, which can be exploited by malicious people to
disclose sensitive information.

Input passed to the "settings[locale]" parameter in forum.php and
profile.php is not properly verified before being used to include
files. This can be exploited to include arbitrary files from local
resources via directory traversal attacks and URL-encoded NULL bytes
("%00").

Successful exploitation requires that "register_globals" is enabled
and that "magic_quotes_gpc" is disabled.

The vulnerabilities are reported in version 1.00. Other versions may
also be affected.

SOLUTION:
Edit the source code to ensure that input is properly verified.
