By Drupal Security Team on
  • 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) 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 6.x-4.0-beta8

Drupal core is not affected. If you do not use the contributed Messaging module, there is nothing you need to do.

Solution

Install the latest version:
