Unauthenticated command execution via unsanitized ip parameter

Published Oct 22, 2025 · Updated Oct 22, 2025

OS command injection in all versions of AMTT Hotel Broadband Operation System allows remote attackers to execute arbitrary system commands. The server_ping.php endpoint embeds the untrusted ip parameter in a shell command without validating or escaping shell metacharacters. No authentication or user interaction is required, and injected commands run with the web server user's privileges.
