Even though the CVE-2016-2183 has been fixed in the etcd components, to enable periodic health checks from kubelet, it was necessary to open up a new port (9979) on etcd grpc-proxy, hence this port might be considered as still vulnerable to the same type of vulnerability. The health checks on etcd grpc-proxy do not contain sensitive data (only metrics data), therefore the potential impact related to this vulnerability is minimal. The CVE-2023-0296 has been assigned to this issue to track the permanent fix in the etcd component."

Aunque el CVE-2016-2183 se corrigi\u00f3 en los componentes de etcd, para permitir comprobaciones peri\u00f3dicas de estado de kubelet, fue necesario abrir un nuevo puerto (9979) en etcd grpc-proxy, por lo que este puerto podr\u00eda considerarse todav\u00eda vulnerables al mismo tipo de vulnerabilidad. Las comprobaciones de estado en etcd grpc-proxy no contienen datos confidenciales (solo datos de m\u00e9tricas), por lo que el impacto potencial relacionado con esta vulnerabilidad es m\u00ednimo.
