   * Advisory ID: DRUPAL-SA-CONTRIB-2014-088
   * Project: Mollom [1]     (third-party module)
   * Version: 6.x, 7.x
   * Date: 2014-September-17
   * Security risk: 11/25 ( Moderately Critical)
     AC:Complex/A:User/CI:Some/II:Some/E:Theoretical/TD:Uncommon [2]
   * Vulnerability: Cross Site Scripting

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

Mollom is an "intelligent" content moderation web service which determines if
a post is potentially spam; not only based on the posted content, but also on
the past activity and reputation of the poster across multiple sites.

Mollom offers a feature to report submitted content as inappropriate which
allows end users to indicate that a piece of site content is objectionable or
out of place.  When reporting content, the content title is not sufficiently
sanitized to prevent cross-site scripting (XSS) attacks.

This vulnerability is mitigated by the fact that an attacker must have a role
with the permission to create content and the content type must be enabled
for "Flag as Inappropriate" within the Mollom advanced configuration settings
(which is not the default setting).


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

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