What is CVE-2018-19441?
CVE-2018-19441 is a medium-severity vulnerability in n/a, published on 27 Jan 2020. It can only be exploited from the same machine or local network, with no action from the victim.
Official description
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.
Weakness: CWE-330
