 'Name' => "Oracle BeeHive 2 voice-servlet prepareAudioToPlay() Arbitrary File Upload",
 '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.
