* Advisory ID: DRUPAL-SA-CONTRIB-2010-001
* Project: Wunderbar! (third-party module)
* Version: 6.x
* Date: 2010-January-6
* Security risk: Not Critical
* Exploitable from: Remote
* Vulnerability: Cross Site Scripting
-------- DESCRIPTION
---------------------------------------------------------
The Wunderbar! module provides a floating bar with configurable buttons and
the ability to link off to social networking sites. The module does not
properly escape user names, potentially allowing a cross site scripting [1]
(XSS) attack which may lead to the user gaining full administrative access.
The risk is mitigated by Drupal's default configuration, which disallows some
characters (<, >, &, and quotes) in user names. A site would only be
vulnerable to this attack if it uses an alternate means to create usernames.
-------- VERSIONS AFFECTED
---------------------------------------------------
* Wunderbar! versions 6.x prior to 6.x-0.6
Drupal core is not affected. If you do not use the Wunderbar! module, there
is nothing you need to do.
-------- SOLUTION
------------------------------------------------------------
Install the latest version:
* If you use Wunderbar! for Drupal 6.x upgrade to Wunderbar! 6.x-0.6 [2]
See also the Wunderbar! project page [3].
