What is CVE-2019-5080?

An exploitable denial-of-service vulnerability exists in the 'I/O-Check' functionality of WAGO’s iocheckd service for specific firmware versions of the PFC 200 and PFC 100 devices. An attacker can send a single, unauthenticated packet to trigger a denial of service, potentially overriding the device's credentials and reverting them to the default documented settings. This may leave the device vulnerable to further attacks, emphasizing the need for immediate security measures.
