The emulator is used infrequently for application logic testing. It is susceptible to an attack only while running in off-line mode. This vulnerability does not exist in Triconex hardware products and therefore has no effect on the operating safety functions in a plant.","published":"2019-05-22T21:29:00.000Z","lastModified":"2026-06-17T02:03:46.000Z","status":"Modified","sourceIdentifier":"cybersecurity@se.com","cvss":{"version":"3.0","score":5.9,"severity":"MEDIUM","vector":"CVSS:3.0/AV:N/AC:H/PR:N/UI:N/S:U/C:N/I:N/A:H"},"cwe":["CWE-754"],"affected":["schneider-electric/triconex tristation emulator"],"epss":{"score":0.01144,"percentile":0.66542,"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 (1.14%).
