Local privilege escalation via mishandled filesystem operations
Published Jun 9, 2020 · Updated Aug 4, 2024
Elevation of privilege in Microsoft Windows Installer allows local users with unprivileged code execution to gain elevated privileges. The installer mishandles certain filesystem operations, but Microsoft has not disclosed the affected operation, path, or validation error. Exploitation requires the ability to execute code locally as an unprivileged user and can raise that user's privileges on the host.
