Published Oct 16, 2020
CVSS 3.1 · 7.1 High
EPSS < 1%
KEV · Not listed
Description
<p>An elevation of privilege vulnerability exists when Microsoft Windows improperly handles reparse points. An attacker who successfully exploited this vulnerability could overwrite or delete a targeted file that would normally require elevated permissions.</p>
<p>To exploit this vulnerability, an attacker would first have to log on to the system. An attacker could then run a specially crafted application that could exploit the vulnerability and overwrite or delete files.</p>
<p>The security update addresses the vulnerability by correcting how Windows handles reparse points.</p>
