* Advisory ID: DRUPAL-SA-CONTRIB-2012-009 * Project: Revisioning [1] (third-party module) * Version: 7.x * Date: 2012-January-18 * Security risk: Less critical [2] * Exploitable from: Remote * Vulnerability: Access bypass -------- DESCRIPTION --------------------------------------------------------- This module enables you to create moderation publication workflows, allowing authors to create content that isn't visible to the public until it has been approved by a moderator/publisher. The module's implementation of hook_node_access() assumes that access is to granted/denied based on the logged-in user's permissions. However, the hook may be invoked in contexts whereby the access grants are to be returned for a particular account passed into the hook. This could result in an access bypass vulnerability if node_access() is called for a specific user account. This vulnerability happens when using the XML sitemap module which as a result will disclose the URLs of un-accessible or unpublished content to anonymous users. The actual content itself is not disclosed. -------- VERSIONS AFFECTED --------------------------------------------------- * Revisioning 7.x-1.x versions prior to 7.x-1.3. Drupal core is not affected. If you do not use the contributed Revisioning [3] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version: * If you use the Revisioning module for Drupal 7.x, upgrade to Revisioning 7.x-1.3 [4]. See also the Revisioning [5] project page. -------- REPORTED BY --------------------------------------------------------- * Dave Reid [6], Drupal Security Team member * Adam Bramley [7] -------- FIXED BY ------------------------------------------------------------ * Dave Reid [8], Drupal Security Team member * Rik de Boer [9], module maintainer -------- COORDINATED BY ------------------------------------------------------ * Dave Reid [10], Drupal Security Team member -------- CONTACT AND MORE INFORMATION ---------------------------------------- The Drupal security team can be reached at security at drupal.org or via the contact form at http://drupal.org/contact [11].
