* Advisory ID: DRUPAL-SA-CONTRIB-2012-023 * Project: Frequently Asked Questions [1] (third-party module) * Version: 6.x * Date: 2012-February-22 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Cross Site Scripting
-------- DESCRIPTION ---------------------------------------------------------
The Frequently Asked Questions (faq) module allows users, with the appropriate permissions, to create question and answer pairs which are displayed on the 'faq' page, and in the random and recent FAQ blocks. The module does not sanitize some of the user-supplied data before displaying it, leading to a Cross Site Scripting (XSS [3]) vulnerability. This vulnerability is mitigated by the fact that the attacker must have a role with the 'administer faq', 'create faq', 'edit faq' or 'edit own faq' permissions. If using the FAQ module with the FAQ Ask module, the attacker may also exploit the vulnerability if they have the 'ask question' permission.
-------- VERSIONS AFFECTED ---------------------------------------------------
* Frequently Asked Questions 6.x-1.x versions prior to 6.x-1.13 [4].
Drupal core is not affected. If you do not use the contributed Frequently Asked Questions [5] module, there is nothing you need to do.
-------- SOLUTION ------------------------------------------------------------
