CVE-2016-0128 is a Microsoft Windows elevation-of-privilege vulnerability in the Security Account Manager (SAM) and Local Security Authority (Domain Policy) (LSAD) remote protocols. Affected Windows versions do not properly establish the RPC channel and accept authentication levels that do not adequately protect that channel. This weakness allows a man-in-the-middle attacker to modify the client-server data stream and downgrade the protection on SAM/LSAD RPC communications. Microsoft describes the issue as caused by the way the SAM and LSAD remote protocols establish the Remote Procedure Call (RPC) channel. Successful exploitation enables the attacker to impersonate an authenticated user over the downgraded channel. The issue is also referred to as the Windows SAM and LSAD Downgrade Vulnerability and is part of the broader BADLOCK set of issues. Affected platforms include Windows Vista SP2, Windows Server 2008 SP2 and R2 SP1, Windows 7 SP1, Windows 8.1, Windows Server 2012 and 2012 R2, Windows RT 8.1, and Windows 10 Gold and 1511.
