CVE-2025-41735 is an unrestricted file upload vulnerability affecting METZ CONNECT EWIO2 devices, including EWIO2-M, EWIO2-M-BM, and EWIO2-BM, running firmware versions earlier than 2.2.0. According to the provided advisory context, the flaw is caused by missing file checks, allowing a low-privileged remote attacker to upload arbitrary files to an arbitrary location on the device. Because the attacker can control both the uploaded content and destination path, successful exploitation can lead to remote code execution on the affected device.
