| Detailed Description |
The Hotfix (MS16-047, 3148527) for 'Security Update for SAM and LSAD Remote Protocols' has not been applied.
This security update resolves a vulnerability in Microsoft Windows. The vulnerability could allow elevation of privilege if an attacker launches a man-in-the-middle (MiTM) attack. An attacker could then force a downgrade of the authentication level of the SAM and LSAD channels and impersonate an authenticated user.
Windows SAM and LSAD Downgrade Vulnerability- CVE-2016-0128
An elevation of privilege vulnerability exists in the Security Account Manager (SAM) and Local Security Authority (Domain Policy) (LSAD) remote protocols when they accept authentication levels that do not protect them adequately. The vulnerability is caused by the way the SAM and LSAD remote protocols establish the Remote Procedure Call (RPC) channel. An attacker who successfully exploited this vulnerability could gain access to the SAM database.
* Note: This check requires an account with administrative privileges which can log into the host to scan. Absence of this condition will result in the check not being performed and a False Negative for all vulnerable hosts.
