Local privilege escalation through Bind Filter Driver
Published Jan 11, 2022 · Updated Jan 2, 2025
Improper privilege management in the Microsoft Windows Bind Filter Driver allows local users to elevate privileges on affected Windows releases. Microsoft has not published the flawed function, operation, or attacker-controlled input within the driver. Exploitation requires existing low-privileged local code execution and grants control within the current operating-system security scope.
