Local privilege escalation to SYSTEM
Published Dec 12, 2023 · Updated Jan 1, 2025
Out-of-bounds read in Microsoft's Cloud Files Mini Filter Driver allows local users to elevate privileges on affected Windows systems. Microsoft identifies the weakness in the driver but has not disclosed the affected routine, input path, or failed boundary check. Exploitation requires local low-privileged access and grants SYSTEM-level control, including data access and system modification.
