CVE-2022-0576Network attack vector

Script execution via unsanitized transport name

Published Feb 13, 2022 · Updated Aug 2, 2024

Cross-site scripting in LibreNMS before 22.1.0 allows remote authenticated users to execute script through an alert transport name. The alert-transports form accepted the transport_id, name, and transport-type request fields without stripping HTML tags, allowing crafted markup to enter generated page content. Access to create or modify alert transports is required, and injected JavaScript runs with the browser privileges of the affected LibreNMS session.
