AnalysisAI

Privilege escalation in Windows Remote Desktop Services (RDS) lets an authenticated, low-privileged attacker elevate to higher privileges across a network by triggering a use-after-free (CWE-416) memory-corruption condition in the RDS component. The flaw spans a broad range of supported Windows client and server releases (Windows 10/11 and Windows Server 2012 through 2025). Microsoft has released a patch; there is no public exploit identified at time of analysis and the issue is not listed in CISA KEV.
