Local privilege escalation via insecure Spotlight image loading
Published Jun 9, 2020 · Updated Aug 4, 2024
Elevation of privilege in Microsoft Windows Lockscreen allows local users to gain elevated privileges through Spotlight image loading. The Lockscreen image-loading path fails to load Spotlight images from a secure location; Microsoft has not disclosed the responsible file, function, or exact validation error. Exploitation requires existing low-privileged local access and grants privileges in the existing Windows security context without user interaction.
