CVE-2022-4070Network attack vector

Continued account access via unexpired disabled-user sessions

Published Nov 20, 2022 · Updated Apr 14, 2025

Insufficient session expiration in LibreNMS before 22.10.0 allows remote authenticated users to retain access after account disablement. The web middleware accepts an existing cookie-authenticated session without checking the user's enabled flag on each request. A valid session established before an administrator disables the account remains usable, preserving that account's authorized access.
