DESCRIPTION:
night_warrior771 has discovered a vulnerability in PHP-Nuke, which
can be exploited by malicious people to conduct script insertion
attacks.

Input passed to the "Story Text" field when submitting news isn't
properly sanitised before being used. This can be exploited to inject
arbitrary HTML and script code, which will be executed in an
administrator's browser session in context of an affected site when
the malicious news is viewed for approval by the administrator.

Example:
<img src=javascript:[code]>
(requires the Microsoft Internet Explorer browser)

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

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