DESCRIPTION:
Haunt IT has discovered a vulnerability in gpEasy CMS, which can be
exploited by malicious people to conduct cross-site scripting
attacks.

Input passed via the "jsoncallback" parameter to index.php (when
"gpreq" is set to "json") 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 2.3.3. Prior versions may
also be affected.

SOLUTION:
Update to version 2.4.
