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.

A privilege escalation vulnerability has been identified in Endress+Hauser's Proline 10 devices. This flaw allows an authenticated user with Operator-level access to elevate their privileges and gain Maintenance-level access, potentially enabling unauthorized configuration changes.

Endress+Hauser has released a security update addressing this issue.
