   * Advisory ID: DRUPAL-SA-CONTRIB-2015-063
   * Project: Webform [1]     (third-party module)
   * Version: 6.x, 7.x
   * Date: 2015-March-04
   * Security risk: 13/25 ( Moderately Critical)
     AC:Basic/A:Admin/CI:Some/II:Some/E:Theoretical/TD:All [2]
   * Vulnerability: Cross Site Scripting

-------- DESCRIPTION
---------------------------------------------------------

Webform enables you to create surveys, personalized contact forms, contests,
and the like.

-------- CROSS SITE SCRIPTING RELATED TO WEBFORM SUBMISSIONS
-----------------

The module doesn't sufficiently escape user data presented to administrative
users in the webform results table. This issue affects the 7.x-4.x branch
only.

This vulnerability is mitigated by the fact that an attacker must have a role
with permission to submit a webform and the administrative user must
subsequently visit the webform's results table tab.

To mitigate this vulnerability, you can disable the view-based results table
and restore the legacy hard-coded results table by adding this line to your
settings.php file:
<?php $conf['webform_table'] = TRUE;
?>

-------- CROSS SITE SCRIPTING RELATED TO BLOCKS
------------------------------

The module doesn't sufficiently escape node titles of webforms which
administrators may make available as blocks and displayed to any user. This
issue affects all 6.x and 7.x branches of the module.

This vulnerability is mitigated by the fact that an attacker must have a role
with permission to administer blocks and create or edit webform nodes.


-------- CVE IDENTIFIER(S) ISSUED
--------------------------------------------

   * /A CVE identifier [3] will be requested, and added upon issuance, in
