      "value": "An issue was discovered in Neato Botvac Connected 2.2.0. The GenerateRobotPassword function of the NeatoCrypto library generates insufficiently random numbers for robot secret_key values used for local and cloud authentication/authorization. If an attacker knows the serial number and is able to estimate the time of first provisioning of a robot, he is able to brute force the generated secret_key of the robot. This is because the entropy of the secret_key exclusively relies on these two values, due to not seeding the random generator and using several constant inputs for secret_key computation. Serial numbers are printed on the packaging and equal the MAC address of the robot."

      "value": "Se detectó un problema en Neato Botvac Connected versión 2.2.0. La función GenerateRobotPassword de la biblioteca NeatoCrypto, genera números aleatorios insuficientemente para los valores de clave secreta del robot usados para la autenticación y autorización local y en la nube. Si un atacante sabe el número de serie y es capaz de estimar el tiempo del primer aprovisionamiento de un robot, puede forzar a partir de fuerza bruta la clave secreta generada del robot. Esto es debido a que la entropía de secret_key se basa exclusivamente en estos dos valores, debido a que el generador aleatorio no realizo el seeding y al usar varias entradas constantes para el cálculo de secret_key. Los números de serie están impresos en el paquete y son iguales a la dirección MAC del robot."
