[security-news at drupal.org]

View online: https://drupal.org/node/2124289

  * Advisory ID: DRUPAL-SA-CONTRIB-2013-086
  * Project: Monster Menus [1] (third-party module)
  * Version: 7.x
  * Date: 2013-October-30
  * Security risk: Critical [2]
  * Exploitable from: Remote
  * Vulnerability: Access bypass

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

Monster Menus includes the ability to protect the visibility of comments for
each node based on hierarchical permissions. However, a carefully-crafted URL
could be used to bypass these permissions, allowing an anonymous user to view
the comments associated with certain nodes.

In order for this flaw to be relevant and exploited, the node itself must be
readable by the attacker. Furthermore, the "Who can read comments" setting
for the node must be something other than "Everyone".
