1. OVERVIEW CubeCart 4.4.6 and lower versions are vulnerable to Local File Inclusion. 2. BACKGROUND CubeCart is an "out of the box" ecommerce shopping cart software solution which has been written to run on servers that have PHP & MySQL support. With CubeCart you can quickly setup a powerful online store which can be used to sell digital or tangible products to new and existing customers all over the world. 3. VULNERABILITY DESCRIPTION CubeCart 4.4.6 and lower versions contain a flaw that may allow a remote attacker to execute arbitrary commands or code. The issue is due to the '/admin.php' script not properly sanitizing user input, specifically directory traversal style attacks (e.g., ../../) supplied to the 'loc' parameter. This may allow an attacker to include a file from the targeted host that contains arbitrary commands or code that will be executed by the vulnerable script. Such attacks are limited due to the script only calling files already on the target host. In addition, this flaw can potentially be used to disclose the contents of any file on the system accessible by the web server. 4. VERSIONS AFFECTED 4.4.6 and lower 5. Affected URL and Parameter /admin.php (loc parameter) /admin.php?_g=filemanager/language&loc=/../../../public_ftp/uploads/hack.inc.php 6. SOLUTION The CubeCart 4.x version family is no longer maintained by the vendor. Upgrade to the currently supported latest CubeCart version - 5.x. 7.
