DESCRIPTION:
A vulnerability has been discovered in PHP-Nuke, which can be
exploited by malicious people to conduct cross-site scripting or
cross-site request forgery attacks.

The vulnerability is caused due to an error within the
anti-cross-site request forgery routine. This can be exploited to
bypass the routine and e.g. execute arbitrary HTML and script code in
a user's browser session in context of an affected site by passing
malicious input to the search function of the downloads module.

Successful exploitation requires that "register_globals" is
disabled.

The vulnerability is confirmed in version 7.9 and reported in version
8. Other versions may also be affected.

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