CVE-2025-41769 is a critical buffer overflow vulnerability in the PROFINET service of multiple Phoenix Contact devices when running in the default configuration. The flaw affects the network-exposed industrial communication service and can be triggered remotely without authentication. The vulnerability is consistent with improper bounds checking during buffer copy operations in the PROFINET service, allowing crafted network input to corrupt memory. Successful exploitation can cause the device to reboot or permit arbitrary code execution on the affected system.
