An attacker who successfully exploited the vulnerability could use the sandbox escape to elevate privileges on an affected system.\nTo exploit the vulnerability, an attacker would first have to log on to the system, and then run a specially crafted application to take control over the affected system.\nThe security update addresses the vulnerability by preventing sandboxed processes from creating reparse points targeting inaccessible files.","published":"2019-08-14T21:15:16.000Z","lastModified":"2026-06-17T02:28:00.000Z","status":"Modified","sourceIdentifier":"secure@microsoft.com","cvss":{"version":"3.1","score":7.9,"severity":"HIGH","vector":"CVSS:3.1/AV:L/AC:L/PR:L/UI:N/S:C/C:H/I:L/A:L"},"cwe":["CWE-862"],"affected":["microsoft/windows 10","microsoft/windows server 2016","microsoft/windows server 2019"],"epss":{"score":0.02433,"percentile":0.84171,"date":"2026-10-27","history":[]},"kev":{"listed":false},"exploits":{"count":1,"verified":true,"firstPublished":"2019-08-26","source":"Exploit-DB (https://gitlab.com/exploit-database/exploitdb)","entries":[{"edbId":47306,"kind":"exploit","title":"Microsoft Windows 10 - SET_REPARSE_POINT_EX Mount Point Security Feature Bypass","url":"https://www.exploit-db.com/exploits/47306","sourceUrl":"https://gitlab.com/exploit-database/exploitdb/-/blob/main/exploits/windows/local/47306.txt","file":"exploits/windows/local/47306.txt","published":"2019-08-26","added":"2019-08-26","updated":"2019-08-27","author":"Google Security Research","type":"local","platform":"windows","port":null,"verified":true,"codes":["CVE-2019-1170"],"tags":null,"aliases":null,"applicationUrl":null,"screenshotUrl":null,"referenceUrl":"https://bugs.chromium.org/p/project-zero/issues/detail?id=1857"}]},"verdict":{"level":"urgent","text":"A public exploit is published in Exploit-DB (verified) and the impact is high, while EPSS rates exploitation at 2.4%.
