[security-news at drupal.org]

View online: http://drupal.org/node/1679442

  * Advisory ID: DRUPAL-SA-CONTRIB-2012-108
  * Project: Drag & Drop Gallery [1] (third-party module)
  * Version: 6.x
  * Date: 2012-July-11
  * Security risk: Highly critical [2]
  * Exploitable from: Remote
  * Vulnerability: Cross Site Scripting, Access bypass, Cross Site Request
    Forgery, SQL Injection, Arbitrary PHP code execution

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

/Important note: Most of the vulnerabilities discussed below can be exploited
when the Drag & Drop Gallery module is disabled on a Drupal site. See
Solution below for details./

The Drag & Drop Gallery creates a gallery node type that allows you add
images to the gallery by dragging and dropping images from your local file
system.

The file handling the actual uploads contains a number of bugs. The
combination of these bugs allows unauthenticated user to upload
PHP-executable files to arbitrary locations. A script exploiting this
vulnerability has been published.

A succesful exploit requires the webserver to be configured in such a way
that it either ignores the .htaccess in the files directory or is able to
write to certain web-accessible directories that do not have this .htaccess
protection.

The module also contains other vulnerabilities such as Cross site scripting
(XSS), SQL-injection, Access bypass and Cross site request forgery (CSRF).
Though less severe, these vulnerabilities can also be used to get
administrator level access to the site.

CVE: Requested

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

  * Drag & Drop Gallery 6.x versions

Drupal core is not affected. If you do not use the contributed Drag & Drop
Gallery [3] module, there is nothing you need to do.

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

There is no version of the module that fixes these vulnerabilites. Disable
*and remove* the module from your system.

Important note: Most vulnerabilities can still be exploited when the module
is disabled.

Please join the issue in the public queue [4] to fix the problems.
