CVE-2023-52093

SYSTEM code execution via exposed NT Listener function

Published Jan 23, 2024 · Updated Aug 29, 2024

Local privilege escalation in Trend Micro Apex One for Windows allows local users to execute arbitrary code as SYSTEM. The Apex One NT Listener service exposes a dangerous function to low-privileged code, but public advisories do not identify the function or the missing validation. Exploitation requires prior ability to run low-privileged code on the target, and successful abuse grants SYSTEM privileges.
