Voting starts in March for the Drupal Association Board election.
- Advisory ID: DRUPAL-SA-CONTRIB-2010-033
- Project: Taxonomy Filter (third-party module)
- Version: 6.x
- Date: 2010-March-31
- Security risk: Critical
- Exploitable from: Remote
- Vulnerability: Cross Site Scripting
The Taxonomy Filter module enables users to filter node listings by multiple taxonomy terms across multiple vocabularies. Vocabulary names, terms, and filter menus are not sanitized, creating a Cross Site Scripting (XSS) vulnerability. Exploiting this vulnerability would allow a malicious user to gain full administrative access, or worse. To exploit the vulnerability a user would either need to have a role with 'administer taxonomy' permission or a site would need to use free tagging and a user would need the ability to create a node that has free tagging enabled.
- Versions of Taxonomy Filter for Drupal 6.x prior to 6.x-1.1
Versions of Taxonomy Filter for Drupal 5.x are not affected. Drupal core is not affected. If you do not use the 6.x version of the contributed Taxonomy Filter module, there is nothing you need to do.
Install the latest version:
- If you use Taxonomy Filter for Drupal 6.x upgrade to Taxonomy Filter 6.x-1.1 or any later version.
Also see the Taxonomy Filter project page.
