What is CVE-2025-54138?

LibreNMS, an auto-discovering PHP/MySQL/SNMP-based network monitoring tool, contains an architectural flaw in the ajax_form.php endpoint. This vulnerability allows for Remote File Inclusion via unvalidated user POST input, specifically through the type parameter. Because this parameter is used directly to include .inc.php files from a designated trusted path, an attacker may exploit this weakness to perform Remote Code Execution if they can manipulate files in the inclusion path. This risk emerges from potential misconfigurations or through symlink exploitation. The issue has been addressed in version 25.7.0.

Affected Version(s)

librenms < 25.7.0
