[Security-news] SA-CONTRIB-2010-001 - Wunderbar - Cross Site Scripting

[security-news at drupal.org]

  * 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]
