Estado: ModificadaAlta (8.4)—

The outdoor unit of Customer Premise Equipment (CPE) product B2338-168 V100R001C00 has a no authentication vulnerability on a certain port. After accessing the network between the indoor and outdoor units of the CPE, an attacker can deliver commands to the specific port of the outdoor unit and execute them without authentication. Successful exploit could allow the attacker to take control over the outdoor unit.
