Upgrade github.com/rancher/rancher/pkg/controllers/user/rbac to version 2.1.6 or higher.

Overview

github.com/rancher/rancher/pkg/controllers/user/rbac is an open source project that provides a container management platform built for organizations that deploy containers in production. Rancher makes it easy to run Kubernetes everywhere, meet IT requirements, and empower DevOps teams.

Affected versions of this package are vulnerable to Access Control Bypass. Project members have continued access to create, update, read, and delete namespaces in a project after they have been removed from it. Furthermore, any project member with access to the default namespace can mount the netes-default service account in a pod, and then use that pod to execute administrative privileged commands against the k8s cluster.

NOTE: This vulnerability has also been identified as: CVE-2018-20321
