This vulnerability is pre-authentication and requires no user interaction. An attacker who successfully exploited this vulnerability could execute arbitrary code on the target system. An attacker could then install programs; view, change, or delete data; or create new accounts with full user rights.\nTo exploit this vulnerability, an attacker would need to send a specially crafted request to the target systems Remote Desktop Service via RDP.\nThe update addresses the vulnerability by correcting how Remote Desktop Services handles connection requests.","published":"2019-08-14T21:15:19.000Z","lastModified":"2026-06-17T02:28:08.000Z","status":"Modified","sourceIdentifier":"secure@microsoft.com","cvss":{"version":"3.1","score":9.8,"severity":"CRITICAL","vector":"CVSS:3.1/AV:N/AC:L/PR:N/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":["microsoft/windows 10","microsoft/windows server 2016","microsoft/windows server 2019"],"epss":{"score":0.08193,"percentile":0.94843,"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":"high","text":"High impact if exploited, but EPSS currently rates exploitation as unlikely (8.19%).
