* Advisory ID: DRUPAL-SA-CONTRIB-2009-076 * Project: Flag Content (third-party module) * Version: 5.x * Date: 2009-October-21 * Security risk: Moderately Critical * Exploitable from: Remote * Vulnerability: Cross Site Scripting
-------- DESCRIPTION ---------------------------------------------------------
The Flag Content module enables users to flag nodes and users for the attention of a site maintainer (e.g. for abuse, spam, trolling, ...etc.). In some specific cases, the module does not sanitize before outputting the Reason field, resulting in a cross-site scripting (XSS [1]) vulnerability. Such an attack may lead to a malicious user gaining full administrative access. -------- VERSIONS AFFECTED ---------------------------------------------------
* Flag Content 5.x-2.x prior to 5.x-2.10
Drupal core is not affected. If you do not use the contributed Flag Content module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------
