DESCRIPTION:
Aliaksandr Hartsuyeu has discovered a vulnerability in foxrum, which
can be exploited by malicious people to conduct script insertion
attacks.

Input passed via the "url" bbcode tag when posting a message isn't
properly verified, before being used. This can be exploited to inject
arbitrary HTML and script code, which will be executed in a user's
browser session in context of an affected site when a malicious link
with the "JavaScript" URI handler is followed from a malicious
message.

The vulnerability has been confirmed in version 4.0.4f. Other
versions may also be affected.

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