Local privilege escalation to SYSTEM
Published Dec 10, 2024 · Updated Jun 9, 2026
Improper access control in Microsoft Office 2016 before 16.0.5478.1000 allows local users to gain SYSTEM privileges. Microsoft has not published the affected Office component or the access-control operation that mishandles a low-privileged request. A low-privileged local account is required; successful exploitation grants SYSTEM-level control without user interaction.
