CVE-2023-3767Public exploitNetwork attack vector

Unauthenticated command execution via settings service control

Published Sep 26, 2023 · Updated Sep 24, 2024

OS command injection in EasyPHP Webserver 14.1 allows remote attackers to execute arbitrary commands through the settings endpoint. The /index.php?zone=settings handler passes the untrusted app_service_control POST value to an operating-system command without neutralization. No authentication or user interaction is required, and commands run with administrative privileges, allowing full control of the Windows host.
