* Advisory ID: DRUPAL-SA-CONTRIB-2012-170 * Project: Multi-Language Link and Redirect (MultiLink) [1] (third-party module) * Version: 6.x, 7.x * Date: 2012-November-28 * Security risk: Moderately critical [2] * Exploitable from: Remote * Vulnerability: Access bypass -------- DESCRIPTION --------------------------------------------------------- MultiLink allows you to generate in-content links to a suitable node or node translation based on the visitor's language preferences. It allows the Node Title of the target node to be shown as the visible text and title attribute for the generated link. Prior to versions 6.x-2.7 and 7.x-2.7 the module doesn't check the the current user has access to a node referenced by the generated link, so that node title (only) may be disclosed to a user who would otherwise have no access to that node. This vulnerability is mitigated by the fact that an attacker must have a role with the permission to edit text using an Input Format for which the MultiLink Filter has been enabled. CVE: Requested -------- VERSIONS AFFECTED --------------------------------------------------- * MulitLink 6.x-2.x versions prior to 6.x-2.7 [3]. * MulitLink 7.x-2.x versions prior to 7.x-2.7 [4]. Drupal core is not affected. If you do not use the contributed Multi-Language Link and Redirect (MultiLink) [5] module, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Install the latest version - see the project page http://drupal.org/project/multilink [6] for downloads.
