          This module exploits an authentication bypass vulnerability in the administration
        console of Openfire servers. By using this vulnerability it is possible to
        upload/execute a malicious Openfire plugin on the server and execute arbitrary Java
        code. This module has been tested against Openfire 3.6.0a.

        It is possible to remove the uploaded plugin after execution, however this might turn
        the server in some kind of unstable state, making re-exploitation difficult. You might
        want to do this manually.
