Protecting Against the Unpatched Kubernetes Vulnerability (CVE-2020-8554)
CVE-2020-8554 is a vulnerability that allows Kubernetes Services to intercept cluster traffic to any IP address. Users who can manage services can exploit the vulnerability to carry out man-in-the-middle (MITM) attacks against pods and nodes in the cluster. All Kubernetes versions including the latest release (v1.20) are vulnerable to this attack. If your cluster is multi-tenant, or allows unprivileged users to create and update services, you are impacted.
