A vulnerability, which was classified as critical, has been found in Neato Botvac Connected 2.2.0. Affected by this issue is the function GenerateRobotPassword of the file authentication/authorization of the component NeatoCrypto Library. The manipulation with an unknown input leads to a random values vulnerability (RNG). Using CWE to declare the problem leads to CWE-330. The product uses insufficiently random numbers or values in a security context that depends on unpredictable numbers. Impacted is confidentiality, integrity, and availability. CVE summarizes:

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.

The weakness was published 01/27/2020. This vulnerability is handled as CVE-2018-19441 since 11/22/2018. The attack needs to be approached locally. No form of authentication is required for exploitation. There are known technical details, but no exploit is available. The MITRE ATT&CK project declares the attack technique as T1600.001.

There is no information about possible countermeasures known. It may be suggested to replace the affected object with an alternative product.
