In order to exploit this vulnerability, an attacker requires privileged access on the engineering workstation to modify a Windows registry key which would divert all traffic updates to go through a server in the attacker's possession. A man-in-the-middle attack is then used to complete the exploit.","published":"2020-07-23T21:15:13.000Z","lastModified":"2026-06-17T03:24:56.000Z","status":"Modified","sourceIdentifier":"cybersecurity@se.com","cvss":{"version":"3.1","score":4.7,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:H/PR:N/UI:R/S:C/C:L/I:L/A:N"},"cwe":["CWE-601"],"affected":["schneider-electric/software update utility"],"epss":{"score":0.00931,"percentile":0.60376,"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 (0.93%).
