CVE-2019-5078 (GCVE-0-2019-5078)

Vulnerability from cvelistv5 – Published: 2019-12-18 20:51 – Updated: 2024-08-04 19:47

Summary

An exploitable denial of service vulnerability exists in the iocheckd service "I/O-Check" functionality of WAGO PFC200 Firmware versions 03.01.07(13) and 03.00.39(12), and WAGO PFC100 Firmware version 03.00.39(12). A specially crafted set of packets can cause a denial of service, resulting in the device entering an error state where it ceases all network communications. An attacker can send unauthenticated packets to trigger this vulnerability.

Severity
