Improper authentication in Windows SMB Server allows an authorized attacker to elevate privileges locally.
AnalysisAI
Windows SMB Server authentication bypass across multiple versions (Windows 10 1607, Windows 11 23h2, Windows Server 2012/2025) permits authenticated local users to escalate privileges with high impact to confidentiality, integrity, and availability. The vulnerability stems from improper authentication validation in the SMB service, allowing a local attacker to gain system-level access without user interaction. No patch is currently available, leaving affected systems vulnerable to privilege escalation attacks from any authenticated user.
Technical ContextAI
Classified as CWE-287 (Improper Authentication). Improper authentication in Windows SMB Server allows an authorized attacker to elevate privileges locally.
RemediationAI
Monitor vendor advisories for a patch.
