Drupal Better Revisions 7.x Cross Site Scripting

View online: http://drupal.org/node/1719402

* Advisory ID: DRUPAL-SA-CONTRIB-2012-122
* Project: Better Revisions [1] (third-party module)
* Version: 7.x
* Date: 2012-August-08
* Security risk: Moderately critical [2]
* Exploitable from: Remote
* Vulnerability: Cross Site Scripting

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

The Better Revisions module changes the built-in revision log text area to a
customizable select list with an optional description field. It also allows
an administrator to make the list and/or description field required.

The module doesn't sufficiently validate strings entered in the
administration interface.

This vulnerability is mitigated by the fact that an attacker must have a role
with the permission "administer better revisions".

CVE: Requested

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

* Better Revisions 7.x-1.x versions prior to 7.x-1.1.

Drupal core is not affected. If you do not use the contributed Better
Revisions [3] module, there is nothing you need to do.

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

Install the latest version:

* If you use the Better Revisions module for Drupal 7.x, upgrade to Better
Revisions 7.x-1.1 [4]

Also see the Better Revisions [5] project page.
