ECOVACS robot lawnmowers and vacuums use a deterministic symmetric key to decrypt firmware updates. An attacker can create and encrypt malicious firmware that will be successfully decrypted and installed by the robot.
ECOVACS robot lawnmowers and vacuums insecurely store audio files used to indicate that the camera is on. An attacker with access to the /data filesystem can delete or modify warning files such that users may not be aware that the camera is on.
ECOVACS robot lawnmowers store the anti-theft PIN in cleartext on the device filesystem. An attacker can steal a lawnmower, read the PIN, and reset the anti-theft mechanism.
ECOVACS robot lawn mowers and vacuums use a shared, static secret key to encrypt BLE GATT messages. An unauthenticated attacker within BLE range can control any robot using the same key.
ECOVACS robot lawnmowers and vacuums use a deterministic root password generated based on model and serial number. An attacker with shell access can login as root.
ECOVACS robot lawnmowers and vacuums are vulnerable to command injection via SetNetPin() over an unauthenticated BLE connection.
