   * Date: 2015-August-19
   * Security risk: 14/25 ( Moderately Critical)

   * Vulnerability: Cross Site Scripting, Access bypass, Multiple
     vulnerabilities

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

.... Cross Site Scripting (XSS)

Ctools in Drupal 6 provides a number of APIs and extensions for Drupal, and
is a dependency for many of the most popular modules, including Views, Panels
and Entityreference. Many features introduced in Drupal Core once lived in
ctools.

This vulnerability can be mitigated by the fact that ctools must load its
javascript on the page and the user has access to submit data through a form
(such as a comment or node) that allows 'a' tags.

This patch is a backport for SA-CORE-2015-003 [3].

.... Access bypass

This module provides a number of APIs and extensions for Drupal, and is a
dependency for many of the most popular modules, including Views, Panels and
Features.

The module doesn't sufficiently verify the "edit" permission for the "content
type" plugins that are used on Panels and similar systems to place content
and functionality on a page.

This vulnerability is mitigated by the fact that the user must have access to
edit a display via a Panels display system, e.g. via Panels pages, Mini
Panels, Panel Nodes, Panelizer displays, IPE, Panels Everywhere, etc.
Furthermore, either a contributed module provides a CTools content type
plugin, or a custom plugin must be written that inherits permissions from
another plugin and must have a different permission defined; if no "edit"
permission is set up for the child object CTools did not check the
permissions of the parent object. One potential scenario would allow people
who did not have edit access to Fieldable Panels Panes panes, which were
specifically set to not be reusable, to edit them despite the person's lack
of access.
