medium Nessus Plugin ID 18430

Synopsis

The remote web server contains a PHP script that is affected by a cross- site scripting vulnerability.

Description

According to its self-reported version number, the installation of MediaWiki running on the remote host is affected by a cross-site scripting vulnerability due to a failure to sanitize user-supplied input passed to certain HTML attributes when including a template inside a style directive when editing an entry. An attacker can exploit this flaw to inject arbitrary HTML and script code to be executed by a user's browser within the context of an affected site.

Solution

Upgrade to MediaWiki 1.3.13 or later if using 1.3 legacy series;
otherwise, upgrade to 1.4.5 or later.
