LibreNMS is an open-source, PHP/MySQL/SNMP-based network monitoring system. A Stored Cross-Site Scripting (XSS) vulnerability in the "Services" tab of the Device page allows authenticated users to inject arbitrary JavaScript through the "descr" parameter when adding a service to a device. This vulnerability could result in the execution of malicious code in the context of other users' sessions, potentially compromising their accounts and enabling unauthorized actions. This vulnerability is fixed in 24.10.0.
