CVE-2024-28872Network attack vector

Unauthenticated service control via CA-signed agent certificate

Published Jul 11, 2024 · Updated Mar 26, 2025

Improper certificate validation in ISC Stork 0.15.0 through 1.15.0 allows remote attackers to control monitored services. The server signs an attacker-submitted agent CSR, while agents accept any certificate from that CA without verifying that the peer is the registered Stork server. Network access to the server and an agent is required; successful abuse can read confidential Kea or BIND 9 data, change configurations, or shut down the agent or monitored service.
