  * Advisory ID: DRUPAL-SA-CONTRIB-2013-044
  * Project: elFinder file manager [1] (third-party module)
  * Version: 6.x, 7.x
  * Date: 2013-April-17
  * Security risk: Highly critical [2]
  * Exploitable from: Remote
  * Vulnerability: Cross Site Request Forgery

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

The elfinder module provides an AJAX-based file manager based on the elFinder
javascript library.

The module doesn't sufficiently verify requests thereby exposing a Cross Site
Request Forgery (CSRF) vulnerability. This would enable an attacker to
create, modify, or delete files on the server.

There are no mitigating factors.


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

  * /A CVE identifier [3] will be requested, and added upon issuance, in
    accordance with Drupal Security Team processes./

-------- VERSIONS AFFECTED  
---------------------------------------------------

  * elfinder 6.x-0.x versions prior to 6.x-0.8.
  * elfinder 7.x-0.x versions prior to 7.x-0.8.

Drupal core is not affected. If you do not use the contributed elFinder file
manager [4] module, there is nothing you need to do.

-------- SOLUTION  
------------------------------------------------------------

Install the latest version:

  * If you use the elfinder module 0.x for Drupal 6.x, upgrade to elfinder
    6.x-0.8 [5] (requires elFinder 1.2 [6] library)
  * If you use the elfinder module 0.x for Drupal 7.x, upgrade to elfinder
    7.x-0.8 [7] (requires elFinder 1.2 [8] library)

Also see the elFinder file manager [9] project page.
