Local privilege escalation via mishandled symlinks
Published Mar 12, 2020 · Updated Aug 4, 2024
Privilege escalation in Microsoft Windows User Profile Service allows local users to gain elevated access through crafted symbolic links. Microsoft identifies improper symlink handling in ProfSvc but does not disclose the affected function or privileged file-system operation. A low-privileged user must first log on locally; successful exploitation permits actions with elevated privileges and can disrupt the system.
