Summary
ECOVACS lawnmowers, vacuums, and other robots contain multiple vulnerabilities. In some cases, using a combination of vulnerabilities, an attacker within Bluetooth range or with appropriate network access can take complete control of a robot device. Some vulnerabilities allow an attacker to access device cameras and microphones. Note that the list of affected products is incomplete.
Vulnerabilities 9
-
Critical 9.6
ECOVACS robot lawnmowers and vacuums command injection
ECOVACS robot lawnmowers and vacuums are vulnerable to command injection via SetNetPin() over an unauthenticated BLE connection.
-
High 7.6
ECOVACS lawnmowers and vacuums deterministic root password
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.
-
High 7.5
ECOVACS lawnmowers and vacuums deterministic firmware encryption key
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.
-
High 7.4
ECOVACS HOME mobile app plugins do not properly validate TLS certificates
ECOVACS HOME mobile app plugins for specific robots do not properly validate TLS certificates. An unauthenticated attacker can read or modify TLS traffic and obtain authentication tokens.
-
High 7.4
ECOVACS lawnmowers and vacuums do not properly validate TLS certificates
ECOVACS lawnmowers and vacuums do not properly validate TLS certificates. An unauthenticated attacker can read or modify TLS traffic, possibly modifying firmware updates.
-
Medium 6.5
ECOVACS lawnmower and vacuum cloud service live video PIN bypass
The cloud service used by ECOVACS robot lawnmowers and vacuums allows authenticated attackers to bypass the PIN entry required to access the live video feed.
-
Medium 6.3
ECOVACS lawnmowers and vacuums static BLE GATT encryption key
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.
-
Low 3.3
ECOVACS lawnmowers cleartext storage of anti-theft PIN
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.
-
Low 2.3
ECOVACS lawnmowers and vacuums insecurely store audio warning files
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.
