Local privilege escalation via improper link resolution
Published Apr 9, 2024 · Updated May 3, 2025
Link-following in Microsoft Windows Server File Server Resource Manager allows local users to elevate privileges through crafted filesystem links. Microsoft identifies improper link resolution before file access but does not disclose the affected function or privileged file operation. Exploitation requires local low-privileged access and user interaction, and successful exploitation grants elevated privileges.
