CVE-2019-11247: Kubernetes API Server Vulnerability


Severity

Medium

Vendor

Pivotal

Description

Pivotal Container Service (1.4.x versions prior to 1.4.3) through its dependency on a vulnerable version of Kubernetes kube-apiserver (affected versions include versions prior to 1.13.9, versions prior to 1.14.5, versions prior to 1.15.2, and versions 1.7, 1.8, 1.9, 1.10, 1.11, 1.12), mistakenly allows access to a cluster-scoped custom resource if the request is made as if the resource were namespaced. Authorizations for the resource accessed in this manner are enforced using roles and role bindings within the namespace, meaning that a user with access only to a resource in one namespace could create, view update or delete the cluster-scoped resource (according to their namespace role privileges).
