   * 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.
