Subject: [Security-news] SA-CONTRIB-2013-004 - Live CSS -
	Arbitrary Code	Execution

View online: http://drupal.org/node/1890318

  * Advisory ID: DRUPAL-SA-CONTRIB-2013-004
  * Project: Live CSS [1] (third-party module)
  * Version: 6.x, 7.x
  * Date: 2012-January-16
  * Security risk: Highly critical [2]
  * Exploitable from: Remote
  * Vulnerability: Arbitrary PHP code execution

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

This module enables you to save CSS and LESS files on the server via your
browser.

The module doesn't check that the file being saved isn't a script or
executable.

This vulnerability is mitigated by the fact that an attacker must have a role
with the permission "administer CSS".

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

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

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

  * Live CSS 6.x-2.x versions prior to 6.x-2.1 [4].
  * Live CSS 7.x-2.x versions prior to 7.x-2.7 [5].

Drupal core is not affected. If you do not use the contributed Live CSS [6]
module, there is nothing you need to do.

-------- SOLUTION

  * If you use the Live CSS module for Drupal 6.x, upgrade to 6.x-2.1 [7].
