SYSTEM code execution via symbolic-link file deletion
Published Sep 28, 2022 · Updated Aug 3, 2024
Link-following in Trend Micro Deep Security Agent 20 before 20.0.0.5394 allows local users to gain SYSTEM privileges on Windows. The Anti-Malware Solution Platform follows an attacker-created symbolic link during a privileged file-deletion operation, causing the service to delete an attacker-selected file. Exploitation requires low-privileged code execution and user interaction on the host; successful abuse enables arbitrary code execution as SYSTEM.
