SA-CONTRIB-2012-100 - SimpleMeta - Cross Site Request Forgery (CSRF)

The Simple Meta module provides a method to set meta tags, such as page title, description and keywords for nodes, views and other pages.

The module doesn’t sufficiently confirm user intent when adding and deleting meta tag entries allowing a malicious user to trick a site admin into deleting entries or adding inappropriate entries.

CVE: CVE-2012-2729

Versions affected

• Simple meta 6.x-1.x all versions prior to 6.x-2.0.

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

Solution

Install the latest version:

• If you use the Simple meta module for Drupal 6.x, upgrade to Simple meta 6.x-2.0

The 6.x-1.x branch is no longer supported and all users of that branch should upgrade to the 6.x-2.x code.

Also see the SimpleMeta project page.
