CVE-2024-50351: LibreNMS has a Reflected XSS ('Cross-site Scripting') in librenms/includes/functions.php

November 15, 2024

A Reflected Cross-Site Scripting (XSS) vulnerability in the “section” parameter of the “logs” tab of a device allows attackers to inject arbitrary JavaScript. This vulnerability results in the execution of malicious code when a user accesses the page with a malicious “section” parameter, potentially compromising their session and enabling unauthorized actions. The issue arises from a lack of sanitization in the “report_this()” function.
