LibreNMS has a Stored XSS ('Cross-site Scripting') in librenms/app/Http/Controllers/Table/EditPortsController.php

Vulnerability Description

LibreNMS is an open-source, PHP/MySQL/SNMP-based network monitoring system. A Stored Cross-Site Scripting (XSS) vulnerability in the "Port Settings" page allows authenticated users to inject arbitrary JavaScript through the "name" parameter when creating a new Port Group. This vulnerability results in the execution of malicious code when the "Port Settings" page is visited after the affected Port Group is added to a device, potentially compromising user sessions and allowing unauthorized actions. This vulnerability is fixed in 24.10.0.
