Local privilege escalation to SYSTEM
Published Mar 12, 2024 · Updated May 3, 2025
Privilege escalation in NTFS in Microsoft Windows allows local users with low privileges to gain SYSTEM-level access. Microsoft identifies improper locking of sensitive data but has not disclosed the affected NTFS routine, memory object, or unsafe operation. Exploitation requires prior local access and low privileges; successful abuse grants SYSTEM-level control of the host.
