A vulnerability in Mitel 6900 Series IP (MiNet) phones excluding 6970, versions 1.8 (1.8.0.12) and earlier, could allow a unauthenticated attacker with physical access to the phone to gain root access due to insufficient access control for test functionality during system startup. A successful exploit could allow access to sensitive information and code execution.
The product performs an authorization check when an actor attempts to access a resource or perform an action, but it does not correctly perform the check.
