• Advisory ID: DRUPAL-SA-CONTRIB-2009-034
  • Project: Taxonomy manager (third-party module)
  • Version: 5.x, 6.x
  • Date: 2009-June-10
  • Security risk: Moderately critical
  • Exploitable from: Remote
  • Vulnerability: Cross Site Scripting


The Taxonomy manager module provides additional tools for administering taxonomy through Drupal. A vocabulary gets displayed in a dynamic tree view, where parent terms can be expanded to list their nested child terms or can be collapsed. The module does not properly escape some user-supplied data, allowing malicious users to insert arbitrary HTML and script code into the administrative pages provided by this module. A user who has the 'administer taxonomy' permission, and (depending on configuration) a user able to add taxonomy terms via free tagging, could attempt a cross site scripting (XSS) attack which may lead to the user gaining full administrative access.

Versions affected

  • Taxonomy manager 6.x prior to 6.x-1.1
  • Taxonomy manager 5.x prior to 5.x-1.2

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