DESCRIPTION:
Janek Vind "waraxe" has discovered a vulnerability in PHP-Nuke, which
can be exploited by malicious people to conduct cross-site scripting
attacks.

Input passed to the "pagetitle" parameter in "header.php" isn't
properly sanitised before being returned to the user. This can be
exploited to execute arbitrary HTML and script code in a user's
browser session in context of an affected site.

Example:
http://[host]/?pagetitle=title</title></head><script+src=http://[host]/script.js?

The vulnerability has been confirmed in version 7.8. Prior versions
may also be affected.

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