   * Advisory ID: DRUPAL-SA-CONTRIB-2015-079
   * Project: Chaos tool suite (ctools) [1]     (third-party module)
   * Version: 6.x, 7.x
   * Date: 2015-March-18
   * Security risk: 13/25 (Moderately Critical)
     AC:Basic/A:None/CI:Some/II:None/E:Theoretical/TD:All [2]
   * Vulnerability: Access bypass, Open Redirect

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

This module provides a set of APIs and tools to improve the developer
experience.

.... Access bypass in autocomplete (Drupal 7 only)

Among other many other things, CTools provides an autocomplete callback for
finding entities by their titles or ID.

In CTools version 1.5, additional checks were created to defend against
leaking titles for entities that the user doesn't have access to. However,
certain edge cases were found to leak this private data.

This vulnerability is mitigated by the fact that you must perform the
autocomplete search on custom entities that don't include an access query
tag, or you must know the ID of the entity whose title you are trying to get.

.... Open redirect in confirmation pages (Drupal 6 and 7)

Also, CTools did not sanitize user provided URLs when processing confirmation
delete pages, thereby exposing an open redirect attack vector.

This vulnerability is mitigated by the fact that a module using CTools must
allow for users to insert a malicious external URL that is sent to the
confirmation page.
