* Advisory ID: DRUPAL-SA-CONTRIB-2012-141 * Project: Mass Contact [1] (third-party module) * Version: 6.x * Date: 2012-September-12 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Access bypass
-------- DESCRIPTION ---------------------------------------------------------
This module allows anyone with permission to send a single message to multiple users of a site, using its roles functionality.
The module doesn't sufficiently check permissions after the form has been submitted.
This vulnerability is mitigated by the fact that an attacker must use a tool of some kind (like the Tamper Data Firefox add-on) to intercept the form submission request in order to modify the settings.
