* Advisory ID: DRUPAL-SA-CONTRIB-2014-109 * Project: Freelinking [1] (third-party module) * Version: 6.x, 7.x * Date: 2014-November-12 * Security risk: 16/25 ( Critical) AC:Basic/A:User/CI:All/II:All/E:Theoretical/TD:Uncommon [2] * Vulnerability: Cross Site Scripting
-------- DESCRIPTION ---------------------------------------------------------
The Freelinking module implements a filter framework for easier creation of HTML links to other pages on the site or to external sites.
The module does not sanitize the node title when providing a link to the node, opening a Cross Site Scripting (XSS) vulnerability.
This vulnerability is mitigated by the fact that the person creating the content containing the link must have a role that allows use of an unsafe text format (e.g. "Full HTML"), or the Freelinking filter must be placed /after/ all text sanitizion filters (e.g. "Limit allowed HTML tags") in an otherwise safe text format (e.g. "Filtered HTML").
Please note that this vulnerability also existed the freelinking_nodetitle.inc in versions prior to 6.x-3.4 and 7.x-3.4, but this was patched in releases 6.x-3.4 and 7.x-3.4.
-------- CVE IDENTIFIER(S) ISSUED --------------------------------------------
* /A CVE identifier [3] will be requested, and added upon issuance, in accordance with Drupal Security Team processes./
-------- VERSIONS AFFECTED ---------------------------------------------------
* Freelinking 6.x-x.x versions prior to 6.x-3.5. * Freelinking 7.x-x.x versions prior to 7.x-3.5.
Drupal core is not affected. If you do not use the contributed Freelinking [4] module, there is nothing you need to do.
-------- SOLUTION ------------------------------------------------------------
Install the latest version:
* If you use the Freelinking module for Drupal 6.x, upgrade to Freelinking 6.x-3.5 [5] * If you use the Freelinking module for Drupal 7.x, upgrade to Freelinking 7.x-3.5 [6]
Please note that the plugin freelinking_path.inc contains multible vulnerabilities and was removed in the releases 6.x-3.3 and 7.x-3.3. You should check to see if this file is still present, and if it is: Remove it from the plugin sub-directory /before/ you install the latest version.
