Synopsis
========

MediaWiki is vulnerable to a cross-site scripting attack that could
allow arbitrary JavaScript code execution.

Background
==========

MediaWiki is a collaborative editing software, used by big projects
like Wikipedia.

Affected packages
=================

    -------------------------------------------------------------------
     Package             /  Vulnerable  /                   Unaffected

Description
===========

MediaWiki fails to escape a parameter in the page move template
correctly.

Impact
======

By enticing a user to visit a specially crafted URL, a remote attacker
could exploit this vulnerability to inject malicious JavaScript code
that will be executed in a user's browser session in the context of the
vulnerable site.

Workaround
==========

There is no known workaround at this time.

Resolution
==========

All MediaWiki users should upgrade to the latest available version:
