| Detailed Description |
The Hotfix (MS16-101, 3178465) for 'Security Update for Windows Authentication Methods' has not been applied.
This security update resolves multiple vulnerabilities in Microsoft Windows. The more severe of the vulnerabilities could allow elevation of privilege if an attacker runs a specially crafted application on a domain-joined system.
Netlogon Elevation of Privilege Vulnerability ? CVE-2016-3300
An elevation of privilege vulnerability exists when Windows Netlogon improperly establishes a secure communications channel to a domain controller. An attacker who successfully exploited the vulnerability could run a specially crafted application on a domain-joined system. To exploit the vulnerability, an attacker would require access to a domain-joined machine that points to a domain controller running either Windows Server 2012 or Windows Server 2012 R2. The update addresses the vulnerability by modifying how Netlogon handles the establishment of secure channels.
Kerberos Security Feature Bypass Vulnerability ? CVE-2016-3237
A security feature bypass vulnerability exists in Windows when Kerberos improperly handles a password change request and falls back to NT LAN Manager (NTLM) Authentication Protocol as the default authentication protocol.
