MyBB xmlhttp.php 'value' Parameter XSS

medium Nessus Plugin ID 53288

Synopsis

The remote web server hosts a web application that is affected by a cross-site scripting vulnerability.

Description

The version of MyBB installed on the remote host is affected by a cross-site scripting vulnerability due to improper validation of user-supplied input to 'value' parameter of the 'xmlhttp.php' script.
A remote attacker can exploit this by enticing a user to click a specially crafted URL.

Note that MyBB may also be affected by an additional cross-site scripting vulnerability. However, Nessus has not tested for the issue.

Solution

Upgrade to MyBB 1.4.15 / 1.6.2 or later.
