DESCRIPTION:
Piotr Duszynski has discovered a vulnerability in PunBB, which can be
exploited by malicious people to conduct cross-site scripting
attacks.

Input passed via the URL to e.g. login.php, misc.php, delete.php,
edit.php, and profile.php (when "csrf_token" is invalid) is not
properly sanitised in include/functions.php 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.

Successful exploitation requires that the victim uses a browser that
does not URL-encode the request (e.g. Internet Explorer 6).

The vulnerability is confirmed in version 1.3.5. Other versions may
also be affected.

SOLUTION:
Update to version 1.3.6.
