CVE-2019-12126Network attack vector

Unauthenticated service access via exposed NodePorts

Published Mar 19, 2020 · Updated Aug 4, 2024

Missing authentication in ONAP DCAE through Dublin allows remote attackers to gain full access to exposed services through NodePorts. OOM deployment charts publish multiple service ports outside the Kubernetes cluster while the corresponding DCAE APIs and UIs accept requests without authenticating them. Every OOM setup is affected; network reachability to any listed NodePort is sufficient for unauthenticated control of the service behind that port.
