Improper authentication in Windows Admin Center allows an authorized attacker to elevate privileges locally.
AnalysisAI
Local privilege escalation in Microsoft Windows Admin Center allows an already-authenticated, low-privileged attacker to elevate to higher privileges by abusing an improper authentication weakness (CWE-287). Any host running the management tool is affected, and successful exploitation yields full confidentiality, integrity, and availability impact on the local system. There is no public exploit identified at time of analysis and it is not listed in CISA KEV, but Microsoft has released a fix.
