The SSH daemon allows root login via key authentication and starts automatically. An attacker with the matching private key can gain a root shell on any affected device, resulting in full system compromise. The key cannot be removed without remounting the file system and survives a factory reset. Vendor notes that this functionality was used only for service purposes.\n\n\nThis issue was fixed in version 3.0.30","published":"2026-09-28T13:17:23.000Z","lastModified":"2026-09-28T17:17:51.000Z","status":"Deferred","sourceIdentifier":"cvd@cert.pl","cvss":{"version":"4.0","score":7.7,"severity":"HIGH","vector":"CVSS:4.0/AV:A/AC:H/AT:N/PR:N/UI:N/VC:H/VI:H/VA:H/SC:N/SI:N/SA:N/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-1242"],"affected":[],"epss":{"score":0.00183,"percentile":0.07788,"date":"2026-10-26","history":[{"date":"2026-09-29","score":0.00183,"percentile":0.07029}]},"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 (0.18%).
