CVE-2022-0575Public exploitNetwork attack vector

Stored script execution via unsanitized device metadata

Published Feb 13, 2022 · Updated Aug 2, 2024

Stored cross-site scripting in LibreNMS before 22.2.0 allows remote authenticated users to execute JavaScript in another user's browser. The Add Device flow stores os_id, hardware, and sysName POST values without stripping HTML tags before affected Devices content renders them. Exploitation requires device-addition access and another user to view that content, exposing browser-accessible data and actions.
