CVE-2025-41733 affects METZ CONNECT EWIO2 devices, including EWIO2-M, EWIO2-M-BM, and EWIO2-BM, running firmware versions earlier than 2.2.0. The commissioning wizard does not validate whether the device has already been initialized. Because this initialization state is not enforced, an unauthenticated remote attacker can send crafted POST requests to the commissioning workflow and set root credentials on a device that should no longer expose that setup path. This results in an authentication bypass condition in which the attacker can effectively take over the administrative identity of the device.
