Ceragon Networks microwave bridges that facilitate wireless voice and data services can be accessed remotely. Ceragon FibeAir IP-10 Microwave Bridges are used in a number of industries, including oil and gas, utilities, the public sector and in enterprise implementations. The CERT Coordination Center at Carnegie Mellon University said it was not aware of a practical solution, and that multiple requests to reach the vendor for a response were not successful. A remote, unauthenticated attacker may be able to gain administrative privileges on the device.
