CVE-2025-54138Public exploitNetwork attack vector

Authenticated code execution via unvalidated form include

Published Jul 22, 2025 · Updated Jul 23, 2025

Remote file inclusion in LibreNMS 25.6.0 and earlier allows remote authenticated users to execute code through ajax_form.php. The endpoint concatenates the POST type value into includes/html/forms/{type}.inc.php and passes the resulting path to include_once without an allowlist. Exploitation also requires control of a file or symlink in that trusted directory, and successful execution runs under the librenms service account.
