MODBUS Server Diagnostic Mode (SCADA) (deprecated)

Medium

Synopsis

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

Description

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.

Solution

Only allow diagnostic sessions from trusted clients.
