CVE-2025-34186Public exploitNetwork attack vector

Unauthenticated full access via inverted exit-code handling

Published Sep 16, 2025 · Updated Sep 16, 2025

Authentication bypass in Ilevia EVE X1/X5 Server 4.7.18.0.eden and earlier allows remote attackers to gain full system access. The /login/login.php handler inserts POST credentials into a shell command passed to system(), then treats any nonzero ilevia_authenticate exit code as success. No credentials or user interaction are required; a quote character can force command failure and create an authorized session.
