What is CVE-2019-5170?

A command injection vulnerability exists in the iocheckd service within the WAGO PFC 200 Firmware, specifically in the function responsible for handling the 'I/O-Check' feature. This vulnerability allows an attacker to exploit a specially crafted XML cache file, which can be placed in a targeted location on the device. When the device parses this malicious file, it takes the extracted hostname and uses it in a system command. This command execution can lead to unauthorized control over the operating system, enabling attackers to perform operations with elevated privileges.
