Improper certificate validation in Windows Active Directory allows an authorized attacker to elevate privileges locally.
AnalysisAI
Local privilege escalation in the Windows Active Directory certificate-validation path lets an already-authenticated attacker on Windows 10 (1607/1809) and Windows Server 2016 through 2025 (including Server Core) improperly validate a certificate to gain higher privileges. Microsoft reported and patched the flaw (CWE-295), but there is no public exploit identified at time of analysis and it is not on CISA KEV. The CVSS 7.8 vector (AV:L/PR:L) confirms an authenticated local attacker with full confidentiality, integrity, and availability impact upon success.
