CVE-2022-0589Network attack vector

Stored script execution via unneutralized form values

Published Feb 15, 2022 · Updated Aug 2, 2024

Stored XSS in LibreNMS before 22.1.0 allows remote authenticated users to execute JavaScript in another user's browser. Transport-group creation and modification plus service and service-template editing store form values without neutralizing HTML before later rendering. A low-privileged account and a subsequent page view are required, exposing the viewer's session context to script-controlled reads and actions.
