• Advisory ID: DRUPAL-SA-2008-041
  • Project: Taxonomy autotagger (third-party module)
  • Version: 5.x
  • Date: 2008-July-2
  • Security risk: Critical
  • Exploitable from: Remote
  • Vulnerability: Cross site scripting and SQL injection


The Taxonomy Autotagger will automatically tag a post with terms from a vocabulary if the terms are found in the content of the post.

The module does not properly use Drupal's database API and inserts values supplied by users directly into queries. This can be exploited by malicious users with the permission to create or edit posts to perform SQL Injection attacks. These attacks may lead to the malicious user gaining administrator access.

The module also displays certain values without appropriate filtering. Malicious users with the permission to create or edit posts are able to exploit this issue and insert arbitrary HTML and script code into pages. Such a cross site scripting attack (XSS) may lead to a malicious user gaining administrator access.

Versions affected

  • Taxonomy Autotagger for Drupal 5.x prior to 5.x-1.8.
