DESCRIPTION:
SirGod has discovered a vulnerability in D-iscussion Board, which can
be exploited by malicious people to disclose sensitive information.

Input passed to the "topic" parameter in general/index.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.

Successful exploitation requires that "magic_quotes_gpc" is
disabled.

also be affected.
