-Depending on the specific implementation of a given device, access to some functionalities via an internal interface might be restricted to individuals with a certain authorization access level, e.g., *LA-3* or *LA-4*. If the interface fails to correctly verify access permissions, an attacker with a lower authorization access level than intended might be able to get access to the restricted functionalities.
