          This module exploits a code execution flaw in the Mutiny 5 appliance. The
        EditDocument servlet provides a file upload function to authenticated users. A
        directory traversal vulnerability in the same functionality allows for arbitrary
        file upload, which results in arbitrary code execution with root privileges. In
        order to exploit the vulnerability a valid user (any role) in the web frontend is
        required. The module has been tested successfully on the Mutiny 5.0-1.07 appliance.
