Description

The remote Windows host is missing a security update. It is, therefore, affected by multiple vulnerabilities :

  • A security downgrade vulnerability exists in Kerberos due to improper handling of password change requests. A man-in-the-middle attacker can exploit this to cause the authentication protocol to fall back to the NT LAN Manager (NTLM) authentication protocol, resulting in a bypass of Kerberos authentication. (CVE-2016-3237)

  • An elevation of privilege vulnerability exists in Windows Netlogon due to a failure to properly establish secure communications to a domain controller. A local attacker who has access to a domain-joined machine that points to a domain controller running either Windows Server 2012 or 2012 R2 can exploit this vulnerability to gain elevated privileges via a specially crafted application. (CVE-2016-3300)
