Risk evaluation
A missing authentication vulnerability exists in the iocheckd service "I/O-Check" functionality. A single packet can cause a denial of service and weaken credentials resulting in the default documented credentials being applied to the device. An attacker can send an unauthenticated packet to trigger this vulnerability.
Mitigation summary
The I/O-Check service protocol is only needed during installation and commissioning, not during normal operations. It is highly recommended to disable the IP-port 6626 after commissioning.
