Sophos Web Protection Appliance end-user-/errdoc.php 'msg' Parameter XSS

medium Nessus Plugin ID 66024

Synopsis

The remote host is running a web application that is affected by a cross-site scripting vulnerability.

Description

The Sophos Web Protection application running on the remote host is affected by a cross-site scripting (XSS) vulnerability in the /end-user-/errdoc.php script due to improper sanitization of user-supplied input passed to the 'msg' parameter. 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 the application is reportedly affected by additional vulnerabilities; however, this plugin has not tested for them.

Solution

Upgrade to Sophos Web Protection Appliance version 3.7.8.2 or later.
