Privilege escalation in Intel Data Migration Software 3.3 and earlier allows local users to gain elevated privileges during installation. The installer assigns overly permissive default access controls to an undisclosed installed object, allowing lower-privileged users to modify it. Exploitation requires an authenticated local user and interaction with the installer; successful abuse grants elevated execution.
