* 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.
