An authenticated attacker who successfully exploited this vulnerability would be able to read sensitive information about the target system.</p>\n<p>To exploit this condition, an authenticated attacker would need to send a specially crafted request to the AD|DNS service. Note that the information disclosure vulnerability by itself would not be sufficient for an attacker to compromise a system. However, an attacker could combine this vulnerability with additional vulnerabilities to further exploit the system.</p>\n<p>The update addresses the vulnerability by correcting how Active Directory integrated DNS (ADIDNS) handles objects in memory.</p>","published":"2020-09-11T17:15:14.000Z","lastModified":"2026-06-17T02:46:46.000Z","status":"Modified","sourceIdentifier":"secure@microsoft.com","cvss":{"version":"3.1","score":6.5,"severity":"MEDIUM","vector":"CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:H/I:N/A:N"},"cwe":[],"affected":["microsoft/windows server 2008","microsoft/windows server 2012","microsoft/windows server 2016","microsoft/windows server 2019"],"epss":{"score":0.03902,"percentile":0.90192,"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 (3.90%).
