[Security-news] SA-CONTRIB-2012-018 - Revisioning - Cross Site Scripting

[security-news at drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2012-018
  * Project: Revisioning [1] (third-party module)
  * Version: 6.x
  * Date: 2012-FEB-08
  * Security risk: Less critical [2]
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

-------- DESCRIPTION  
---------------------------------------------------------

The Drupal Revisioning module (https://drupal.org/project/revisioning [3])
"is a module for the configuration of workflows to create, moderate and
publish content revisions."
The Revisioning module contains a persistent cross site scripting (XSS)
vulnerability due to the fact that it fails to sanitize tags before display.

Users with the ability to create content and tags that are submitted to a
review queue could include malicious JavaScript or HTML as part of their
tags. Users reviewing the queue would then become victims of the XSS attack.

The risk is mitigated by the fact that the attacker must have the ability to
create taxonomy terms (either "administer taxonomy" or via a freetagging
vocabulary).

-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Revisioning 6.x-3.13 and prior.

Drupal core is not affected. If you do not use the contributed Revisioning
[4] module, there is nothing you need to do.

-------- SOLUTION  
------------------------------------------------------------

Install the latest version:

  * Upgrade to Revisioning 6.x-3.14 [5]

See also the Revisioning [6] project page.
