Synopsis

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

Description

The version of MediaWiki running on the remote host is affected by a cross-site scripting vulnerability due to a failure to properly sanitize user-supplied input to the 'uselang' parameter in the 'index.php' script. An attacker can exploit this to inject arbitrary HTML and script code into a user's browser to be executed within the security context of the affected site.

Solution

Upgrade to MediaWiki 1.17.5 / 1.18.4 / 1.19.1 or later.
