Cloud Native Computing Foundation (CNCF) CNI (Container Networking
Interface) 0.7.4 has a network firewall misconfiguration which affects
Kubernetes. The CNI ‘portmap’ plugin, used to setup HostPorts for CNI,
inserts rules at the front of the iptables nat chains; which take
precedence over the KUBE- SERVICES chain. Because of this, the
HostPort/portmap rule could match incoming traffic even if there were
better fitting, more specific service definition rules like NodePorts later
in the chain. The issue is fixed in CNI 0.7.5 and Kubernetes 1.11.9,
1.12.7, 1.13.5, and 1.14.0.
