        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.
