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.
