A flaw was found in the Microsoft Windows Netlogon Remote Protocol (MS-NRPC), where it reuses a known, static, zero-value initialization vector (IV) in AES-CFB8 mode. This flaw allows an unauthenticated attacker to impersonate a domain-joined computer, including a domain controller, and possibly obtain domain administrator
privileges. The highest threat from this vulnerability is to confidentiality, integrity, as well as system availability.
