An attacker who obtains the private key and captures an\nHTTP Web UI login session may use the key to decrypt the administrator\npassword. \n\n\n\n\n\nSuccessful\nexploitation may disclose the administrator password captured from an HTTP\nlogin session and compromise session confidentiality.","published":"2026-09-03T23:17:19.000Z","lastModified":"2026-10-27T18:17:37.000Z","status":"Deferred","sourceIdentifier":"f23511db-6c3e-4e32-a477-6aa17d310630","cvss":{"version":"4.0","score":6.1,"severity":"MEDIUM","vector":"CVSS:4.0/AV:A/AC:L/AT:P/PR:N/UI:N/VC:H/VI:L/VA:L/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-321"],"affected":[],"epss":{"score":0.00258,"percentile":0.17365,"date":"2026-10-26","history":[]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"low","text":"Lower severity and a low EPSS score (0.26%).
