Descriptions

In Rancher 1 and 2 through 2.2.3, unprivileged users (if allowed to deploy nodes) can gain admin access to the Rancher management plane because node driver options intentionally allow posting certain data to the cloud. The problem is that a user could choose to post a sensitive file such as /root/.kube/config or /var/lib/rancher/management-state/cred/kubeconfig-system.yaml.

En Rancher versión 1 y versión 2 hasta 2.2.3, usuarios sin privilegios (si se les permite desplegar nodos) pueden obtener acceso de administrador al plano de administración Rancher ya que las opciones de controladores de nodo permiten intencionalmente publicar ciertos datos en la nube. El problema es que un usuario puede elegir publicar un archivo confidencial como /root/.kube/config o /var/lib/rancher/management-state/cred/kubeconfig-system.yaml
