MODBUS Server Diagnostic Mode (SCADA) (deprecated)



The remote host may give an attacker information useful for future attacks.


The remote server is running the MODBUS protocol. This protocol is common on SCADA or process control networks. In addition, the PLC is running with 'Diagnostics' enabled. This is very dangerous, as it can give attackers information that can be used to exploit the machine.


Only allow diagnostic sessions from trusted clients.
