CVE-2025-41690
A low-privileged attacker in bluetooth range may be able to access the password of a higher-privilege user (Maintenance) by viewing the device’s event log. This vulnerability could allow the Operator to authenticate as the Maintenance user, thereby gaining unauthorized access to sensitive configuration settings and the ability to modify device parameters.

If an immediate firmware update is not feasible, it is recommended to disable the device's Bluetooth communication when not actively in use. This significantly reduces the risk of unauthorized access by eliminating the key vector through which the vulnerability could be exploited.
