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.","publishedAt":"2020-01-27T18:33:37.000Z","updatedAt":"2024-08-05T11:37:11.452Z","severity":null,"assigner":"mitre","products":["n/a n/a"],"affected":[{"vendor":"n/a","product":"n/a","versions":[{"version":"n/a","status":"affected"}]}],"references":["https://www.youtube.com/watch?v=k5nj7Jhwn9c","https://www.usenix.org/system/files/woot19-paper_ullrich.pdf"],"weaknesses":[],"ingestedAt":"2026-10-29T19:44:34.704Z","source":{"repository":"CVEProject/cvelistV5","path":"cves/2018/19xxx/CVE-2018-19441.json","commit":"556c9d3a8cd17e218bb8e452ba7cd619a384ff47"},"raw":{"dataType":"CVE_RECORD","dataVersion":"5.1","cveMetadata":{"cveId":"CVE-2018-19441","state":"PUBLISHED","datePublished":"2020-01-27T18:33:37.000Z","dateUpdated":"2024-08-05T11:37:11.452Z","assignerShortName":"mitre","assignerOrgId":"8254265b-2729-46b6-b9e3-3dfca2d5bfca","dateReserved":"2018-11-22T00:00:00.000Z"},"containers":{"cna":{"descriptions":[{"lang":"en","value":"An issue was discovered in Neato Botvac Connected 2.2.0.
