Communication to the AMC2 uses a state-of-the-art cryptographic algorithm for symmetric encryption called Blowfish. An attacker could retrieve the key from the firmware to decrypt network traffic between the AMC2 and the host system. Thus, an attacker can exploit this vulnerability to decrypt and modify network traffic, decrypt and further investigate the devices firmware file, and change the device configuration. The attacker needs to have access to the local network, typically even the same subnet.
The use of a hard-coded cryptographic key significantly increases the possibility that encrypted data may be recovered.
