This may allow the threat actor to make malicious changes to the database that will be deployed when a legitimate FactoryTalk Policy Manager user deploys a security policy model. User interaction is required for this vulnerability to be successfully exploited.\n\n","published":"2023-06-13T21:15:10.000Z","lastModified":"2026-06-17T05:53:04.000Z","status":"Modified","sourceIdentifier":"PSIRT@rockwellautomation.com","cvss":{"version":"3.1","score":8.2,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:R/S:C/C:H/I:H/A:H"},"cwe":["CWE-321","CWE-798"],"affected":["rockwellautomation/factorytalk policy manager","rockwellautomation/factorytalk system services"],"epss":{"score":0.00203,"percentile":0.09727,"date":"2026-10-23","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 (0.20%).
