Local privilege escalation via symbolic-link parsing
Published Mar 12, 2020 · Updated Aug 4, 2024
Elevation of privilege in the Microsoft Windows kernel allows local users with low privileges to gain elevated rights via crafted symbolic links. The kernel's symbolic-link parser improperly handles certain link structures; Microsoft has not disclosed the specific parser routine or validation error. Successful exploitation crosses a local privilege boundary and grants control at a higher security context without user interaction.
