high Nessus Plugin ID 92823
Language:
Synopsis
The remote Windows host is affected by multiple vulnerabilities.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)
Solution
Microsoft has released a set of patches for Windows Vista, 2008, 7, 2008 R2, 2012, 8.1, RT 8.1, 2012 R2, and 10.See Also
