CVE-2022-0587Public exploitNetwork attack vector

Privilege escalation via missing plugin admin authorization

Published Feb 15, 2022 · Updated Aug 2, 2024

Improper authorization in LibreNMS before 22.2.0 allows remote authenticated users to change plugin settings via the web interface. Plugin settings routes and alert transport handling lacked a global-admin authorization guard, so normal users could enable or disable installed plugins and manage plugin data. Access requires a valid low-privilege account; the documented impact is unauthorized integrity changes, with no availability impact reported.
