An attacker who successfully exploited the vulnerability could execute arbitrary code with elevated permissions on a target system. To exploit the vulnerability, an attacker could create a specially crafted request, causing Windows to execute arbitrary code with elevated permissions. The security update addresses the vulnerability by correcting how Windows Deployment Services TFTP Server handles objects in memory, aka 'Windows Deployment Services TFTP Server Remote Code Execution Vulnerability'.","published":"2019-04-08T23:29:00.000Z","lastModified":"2026-06-17T02:08:31.000Z","status":"Modified","sourceIdentifier":"secure@microsoft.com","cvss":{"version":"3.0","score":7.5,"severity":"HIGH","vector":"CVSS:3.0/AV:N/AC:H/PR:L/UI:N/S:U/C:H/I:H/A:H"},"cwe":[],"affected":["microsoft/windows 10","microsoft/windows 7","microsoft/windows 8.1","microsoft/windows rt 8.1","microsoft/windows server 2008","microsoft/windows server 2012","microsoft/windows server 2016","microsoft/windows server 2019"],"epss":{"score":0.34209,"percentile":0.98396,"date":"2026-10-27","history":[{"date":"2026-09-21","score":0.17919,"percentile":0.97111},{"date":"2026-09-22","score":0.34209,"percentile":0.98334}]},"kev":{"listed":false},"exploits":{"count":0,"verified":false,"firstPublished":null,"source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[]},"verdict":{"level":"urgent","text":"EPSS puts the probability of exploitation in the next 30 days at 34.2%, higher than 98% of all known CVEs.
