The commissioning wizard on the affected devices does not validate if the device is already initialized. An unauthenticated remote attacker can construct POST requests to set root credentials.
Weakness
The authentication algorithm is sound, but the implemented mechanism can be bypassed as the result of a separate weakness that is primary to the authentication error.
