DESCRIPTION:

which can be exploited by malicious people to conduct cross-site
scripting attacks.

Input passed to the "rs" parameter in ajaxp_backend.php is not
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.

The vulnerability is confirmed in version 4.0 trial edition. Other
versions may also be affected.
