CVE-2021-23207

User impersonation via registry-exposed JWT secrets

Published Jan 21, 2022 · Updated Apr 16, 2025

Credential exposure in Fresenius Kabi Vigilant Master Med before 2.0.1.3 and Agilia Partner before 3.0 allows local users to forge JWTs. Vigilant Master Med stores JWT-signing secrets in the Windows registry without sufficient protection, allowing extracted values to sign valid tokens for arbitrary identities. Physical access to the host is required; forged identities can alter RabbitMQ queues and messages, while the public record does not explain Agilia Partner's vulnerable locus.
