CVE-2025-71211Network attack vector

Unauthenticated code execution via unvalidated console input

Published May 21, 2026 · Updated May 21, 2026

Path traversal in Trend Micro Apex One products allows remote attackers to execute code through the management console. The console passes a user-supplied string to a system call without validation, allowing code upload and execution as IUSR in Apex One before 14.0.0.14136 and Apex One as a Service before 14.0.20315. Authentication is not required, but the attacker must reach the console on TCP port 8080 or 4343; the affected executable and input are undisclosed.
