DESCRIPTION:

Input passed in a signature is not properly sanitised before being
used in "privmsg.php" and "viewtopic.php". 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 the
malicious user data is viewed.

The vulnerability has been reported in version 2.0.13. Other versions
may also be affected.

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