- Advisory ID: DRUPAL-SA-CONTRIB-2012-104
- Project: Privatemsg (third-party module)
- Version: 7.x
- Date: 2012-June-20
- Security risk: Moderately critical
- Exploitable from: Remote
- Vulnerability: Cross Site Scripting
Description
The Privatemsg module allows users to send private messages between to each other. The module doesn't sufficiently sanitize user names when creating messages.
This vulnerability is mitigated by the fact that it is not possible to create insecure user names through the default user interface. The exploit is only possible in combination with another module that allows this, such as Realname which allows site-builders to choose fields to display an alternative username.
CVE: CVE-2012-4468
Versions affected
- Privatemsg 7.x-1.x versions prior to 7.x-1.3
Drupal core is not affected. If you do not use the contributed Privatemsg module, there is nothing you need to do.
Solution
Install the latest version:
- If you use the Privatemsg module for Drupal 7, upgrade to Privatemsg 7.x-1.3
