The affected devices allow a factory reset to be executed without the required privileges due to improper privilege management as well as manipulation of configuration data because of leaked privileges of previous sessions. This could allow an unauthorized attacker to escalate their privileges.","published":"2025-09-09T09:15:37.000Z","lastModified":"2026-10-23T22:10:00.000Z","status":"Modified","sourceIdentifier":"productcert@siemens.com","cvss":{"version":"4.0","score":6.9,"severity":"MEDIUM","vector":"CVSS:4.0/AV:L/AC:H/AT:P/PR:N/UI:A/VC:N/VI:H/VA:L/SC:N/SI:H/SA:L/E:X/CR:X/IR:X/AR:X/MAV:X/MAC:X/MAT:X/MPR:X/MUI:X/MVC:X/M"},"cwe":["CWE-269"],"affected":["siemens/sinamics g220 firmware","siemens/sinamics s200 firmware","siemens/sinamics s210 firmware"],"epss":{"score":0.00209,"percentile":0.10903,"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":"low","text":"Lower severity and a low EPSS score (0.21%).
