New! CVE Severity Now Using CVSS v3

The calculated severity for CVEs has been updated to use CVSS v3 by default. CVEs that do not have a CVSS v3 score will fall back CVSS v2 for calculating severity. Severity display preferences can be toggled in the settings dropdown.

Description

Microsoft Windows 8.1 and Windows RT 8.1, Windows Server 2012 R2, Windows 10 Gold, 1511, 1607, and 1703, and Windows Server 2016 allow an attacker to set variables that are either read-only or require authentication when Windows fails to enforce case sensitivity for certain variable checks, aka "Windows Security Feature Bypass Vulnerability".
