CVE-2021-23233Network attack vector

Unauthenticated configuration modification via unprotected endpoints

Published Jan 21, 2022 · Updated Apr 16, 2025

Improper access control in Fresenius Kabi Link+ Agilia before 3.0 allows remote attackers to modify critical configuration. Sensitive web endpoints accept requests without verifying a session cookie or other authentication information before performing critical actions. Network access to the device is sufficient; published material does not identify the endpoint paths, and the bounded consequences include configuration changes and other critical actions.
