Subsequently, the default password of root for the root account allows an attacker to conduct remote code execution and as a result take over the system.","published":"2019-03-21T16:00:28.000Z","lastModified":"2026-06-17T01:47:22.000Z","status":"Modified","sourceIdentifier":"cve@mitre.org","cvss":{"version":"3.0","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.0/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":["CWE-798"],"affected":["patlite/nbm-d88n firmware","patlite/nhl-3fb1 firmware","patlite/nhl-3fv1n firmware"],"epss":{"score":0.05647,"percentile":0.92923,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (5.65%).
