* Advisory ID: DRUPAL-SA-CONTRIB-2009-013 * Project: Content Construction Kit (third-party module) * Version: 6.x * Date: 2009 March 18 * Security risk: Moderately critical * Exploitable from: Remote * Vulnerability: Cross-site scripting (XSS)

-------- DESCRIPTION ---------------------------------------------------------

The Node reference and User reference sub-modules, which are part of the Content Construction Kit (CCK) project, lets administrators define node fields that are references to other nodes or to users. When displaying a node edit form, the titles of candidate referenced nodes or names of candidate referenced users are not properly filtered, allowing malicious users to inject arbitrary code on those pages. Such a cross site scripting [1] (XSS) attack may lead to a malicious user gaining full administrative access. -------- VERSIONS AFFECTED ---------------------------------------------------

* Versions of CCK for Drupal 6.x prior to 6.x-2.2

Drupal core is not affected. If you do not use the Node reference or User reference sub-modules of the contributed Content Construction Kit (CCK) project, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------

Install the latest version: * If you use CCK for Drupal 6.x upgrade to CCK 6.x-2.2 [2]

See also the Content Construction Kit (CCK) project page [3]. -------- REPORTED BY ---------------------------------------------------------
