Loading vulnerability…
A vulnerability in Shopware before version 5.3.4 allows an attacker to trigger XML External Entity (XXE) attacks via the 'sort' parameter to the loadPreviewAction() method in the Shopware_Controllers_Backend_ProductStream controller. The vulnerability arises from unsafe instantiation of a SimpleXMLElement object with user-supplied data, leading to potential XXE exploitation.

This repository contains a single Metasploit module targeting Shopware (versions 5.3 to 5.6) via a PHP object instantiation vulnerability (CVE-2019-12799). The exploit requires valid backend credentials and leverages insufficient input validation in the createInstanceFromNamedArguments function to achieve PHP object injection. The module authenticates to the Shopware backend, leaks the webroot and CSRF token, crafts a malicious PHAR archive containing a PHP webshell, uploads it, and triggers deserialization to write the webshell to the server. The resulting webshell allows arbitrary PHP code execution via a custom HTTP header. The module is fully weaponized, providing automated exploitation and cleanup via the Metasploit framework. The main attack vector is network-based, targeting HTTP endpoints in the Shopware backend. The code is well-structured and leverages Metasploit's HttpClient and FileDropper mixins for HTTP communication and file management.
