CVE-2021-33843Network attack vector

Unauthenticated network settings modification via configuration page

Published Jan 21, 2022 · Updated Apr 16, 2025

Missing authentication in Fresenius Kabi Agilia Connect WiFi Module before D25 allows remote attackers to modify network settings. The module exposes a default configuration page without authentication and accepts changes to configuration values supplied through that page. Network access to the pump is sufficient; the documented consequence is unauthorized configuration modification, not data disclosure or service interruption.
