The Akuvox E11 Media Access Control (MAC) address, a primary identifier, combined with the Akuvox E11 IP address, could allow an attacker to identify the device on the Akuvox cloud.

The Akuvox E11 libvoice library provides unauthenticated access to the camera capture for image and video. This could allow an attacker to view and record image and video from the camera.

Akuvox E11 appears to be using a custom version of dropbear SSH server. This server allows an insecure option that by default is not in the official dropbear SSH server.

Akuvox E11 contains a function that encrypts messages which are then forwarded. The IV vector and the key are static, and this may allow an attacker to decrypt messages.

Akuvox E11 cloud login is performed through an unencrypted HTTP connection. An attacker could gain access to the Akuvox cloud and device if the MAC address of a device if known.

Akuvox E11 uses a hard-coded cryptographic key, which could allow an attacker to decrypt sensitive information.
