What is CVE-2024-49758?

A vulnerability exists in the LibreNMS network monitoring system, specifically affecting the ability of users with Admin roles to add notes to devices. Due to inadequate sanitization of user input, if JavaScript code is included within the device's notes, it can be executed when the ExamplePlugin is enabled. This oversight can lead to Cross-Site Scripting (XSS) attacks, potentially compromising the integrity and confidentiality of the system. The issue has been addressed in version 24.10.0, urging users to update promptly to mitigate this risk.
