[IT-SecNots] [Security-news] SA-CONTRIB-2011-010 - Messaging - Cross Site Scripting

[security-news AT drupal.org]

  * Advisory ID: DRUPAL-SA-CONTRIB-2011-010
  * Project: Messaging (third-party module)
  * Version: 6.x
  * Date: 2011-February-16
  * Security risk: Moderately critical
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting

The Messaging module is a Framework to allow message sending in a channel
independent way. It provides a common API for message composition and sending
while allowing plug-ins for multiple messaging methods. The module does not
sanitize some of the user-supplied data before displaying it, leading to a
Cross Site Scripting (XSS [1]) vulnerability that may lead to a malicious
user gaining full administrative access. This vulnerability is mitigated by
the fact that the attacker must have a role with the 'administer messaging'
permission which should generally only be granted to trusted roles.
-------- VERSIONS AFFECTED  
---------------------------------------------------

  * Messaging module for Drupal 6.x versions prior to 6.x-2.4 and
