CVE-2025-54948Known exploitationNetwork attack vector

Unauthenticated code execution via unvalidated system call

Published Aug 5, 2025 · Updated Oct 21, 2025

OS command injection in Trend Micro Apex One 2019 before 14.0.0.14039 allows remote attackers to execute code through its management console. The console passes a user-supplied string to a system call without proper validation, executing attacker-controlled code as IUSR. The console must be reachable on its default TCP ports 8080 or 4343; no authentication or user interaction is required.
