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.
