Windows Security Feature Bypass Vulnerability - CVE-2020-16910

oval:org.cisecurity:def:8373

A security feature bypass vulnerability exists when Microsoft Windows fails to handle file creation permissions which could allow an attacker to create files in a protected Unified Extensible Firmware Interface (UEFI) location. To exploit this vulnerability an attacker could run a specially crafted application to bypass Unified Extensible Firmware Interface (UEFI) variable security in Windows. The security update addresses the vulnerability by correcting security feature behavior to enforce permissions.
