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.","severity":{"version":"3.1","score":4.7,"vector":"CVSS:3.1/AV:L/AC:H/PR:L/UI:N/S:U/C:H/I:N/A:N","level":"medium","assessor":"primary","from":"nvd"},"epss":{"day":"2026-11-07","score":0.00296,"percentile":0.22368,"model":"v2026.06.15"},"facts":{"in_kev":false,"known_exploited":false,"public_exploit":false,"fix_available":false},"cwes":["CWE-330"],"published":"2020-01-27T18:33:37Z","modified":"2026-06-17T01:49:18Z","products":[{"vendor":"neatorobotics","product":"botvac_connected_firmware"}],"references":[{"url":"https://www.youtube.com/watch?v=k5nj7Jhwn9c","tags":["x_refsource_MISC","x_transferred","Third Party Advisory"]},{"url":"https://www.usenix.org/system/files/woot19-paper_ullrich.pdf","tags":["x_refsource_MISC","x_transferred","Third Party Advisory"]},{"url":"https://nvd.nist.gov/vuln/detail/CVE-2018-19441"},{"url":"https://github.com/advisories/GHSA-4f4h-4mvr-gm9g"}],"sources":{"cve":[{"id":"CVE-2018-19441","description":"An issue was discovered in Neato Botvac Connected 2.2.0.
