Description
LibreNMS is an open-source, PHP/MySQL/SNMP-based network monitoring system. A Self Cross-Site Scripting (Self-XSS) vulnerability in the "Alert Templates" feature allows users to inject arbitrary JavaScript into the alert template's name. This script executes immediately upon submission but does not persist after a page refresh.
