View online: https://www.drupal.org/node/2308503 * Advisory ID: DRUPAL-SA-CONTRIB-2014-072 * Project: freelinking [1] (third-party module) * Project: freelinking case tracker [2] (third-party module) * Version: 6.x, 7.x * Date: 2014-July-23 * Security risk: Critical [3] * Exploitable from: Remote * Vulnerability: Access bypass -------- DESCRIPTION --------------------------------------------------------- The freelinking and freelinking case tracker modules implement a filter for the easier creation of HTML links to other pages in the site or external sites with a wiki style format such as [[pluginname:identifier]]. The module doesn't sufficiently check access to content when displaying links to nodes and users. This makes it possible to see node titles, usernames and potentially other data depending on the site configuration. This vulnerability is mitigated by the fact that a site must use node access or permissions to prevent some users from viewing some nodes or users. -------- CVE IDENTIFIER(S) ISSUED -------------------------------------------- * /A CVE identifier [4] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./ -------- VERSIONS AFFECTED --------------------------------------------------- All versions of Freelinking and Freelinking for case tracker Drupal core is not affected. If you do not use the contributed freelinking [5] or freelinking Case tracker [6] modules, there is nothing you need to do. -------- SOLUTION ------------------------------------------------------------ Uninstall the module, it is no longer maintained. Also see the freelinking [7] and freelinking case tracker [8] project pages. -------- REPORTED BY --------------------------------------------------------- * Chris Burgess [9] -------- 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 [10].
