Elemental Path's CogniToys Dino smart toys through firmware version 0.0.794 share a fixed small pool of hardcoded keys, allowing a remote attacker to use a different Dino device to decrypt VoIP traffic between a child's Dino and remote server.

Elemental Path's CogniToys Dino smart toys through firmware version 0.0.794 do not provide sufficient protections against capture-replay attacks, allowing an attacker on the network to replay VoIP traffic between a Dino device and remote server to any other Dino device.

Elemental Path's CogniToys Dino smart toys through firmware version 0.0.794 use AES-128 with ECB mode to encrypt voice traffic between the device and remote server, allowing a malicious user to map encrypted traffic to a particular AES key index and gaining further access to eavesdrop on privacy-sensitive voice communication of a child and their Dino device.
