DESCRIPTION:
matrix_killer has discovered a vulnerability in w-Agora, which can be
exploited by malicious people to disclose certain sensitive
information.

Input passed to the "site" parameter in index.php is not properly
verified before being used to include files. This can be exploited to
include arbitrary files from local resources.

Example:
http://[host]/w-agora/index.php?site=[file]%00 

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

The vulnerability has been confirmed in version 4.2.0. Other versions
may also be affected.

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