WordPress 3.3.x < 3.3.1 XSS Vulnerability

Description

According to its self-reported version number, the WordPress application running on the remote web server is 3.3.x prior to 3.3.1. It is, therefore, affected by a cross-site scripting (XSS) vulnerability. An unauthenticated, remote attacker can exploit this, via a specially crafted request, to execute arbitrary script code in a user's browser session.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.
