Windows PKU2U Elevation of Privilege Vulnerability

FAQ

What is PKU2U?

PKU2U is a peer-to-peer authentication protocol. This setting prevents online identities from authenticating to domain-joined systems. Authentication will be centrally managed with Windows user accounts.

How do I know if my servers are exploitable by this vulnerability?

If your servers are not configured to allow the use of PKU2U authentication, they would not be vulnerable. In all cases, Microsoft strongly recommends that you install the updates for this vulnerability as soon as possible even if you do not use PKU2U authentication. Please see Network security Allow PKU2U authentication requests to this computer to use online identities for more information.
