CVE-2025-59353Network attack vector

Peer impersonation via unchecked certificate IP addresses

Published Sep 17, 2025 · Updated Sep 17, 2025

Improper authorization in dragonflyoss Dragonfly before 2.1.0 allows remote attackers to obtain mTLS certificates for arbitrary IP addresses. The Manager Certificate gRPC service verifies a CSR signature but copies requested IP addresses into the certificate without checking that they match the connection source. Network access to that service is sufficient, and a certificate for another peer's address defeats peer identity checks and permits impersonation.
