Descriptions
In all Kubernetes versions prior to v1.10.11, v1.11.5, and v1.12.3, incorrect handling of error responses to proxied upgrade requests in the kube-apiserver allowed specially crafted requests to establish a connection through the Kubernetes API server to backend servers, then send arbitrary requests over the same connection directly to the backend, authenticated with the Kubernetes API server's TLS credentials used to establish the backend connection.
En todas las versiones de Kubernetes anteriores a la v1.10.11, v1.11.5 y la v1.12.3, el manejo incorrecto de las respuestas de error a las peticiones de actualización en el proxy en kube-apiserver permitían que las peticiones especialmente manipuladas estableciesen una conexión mediante el servidor de la API de Kubernetes a los servidores del backend y enviasen peticiones arbitrarias en la misma conexión directamente al backend, autenticadas con las credenciales TLS del servidor de la API de Kubernetes empleadas para establecer la conexión con el backend.
A privilege escalation vulnerability exists in OpenShift Container Platform which allows for compromise of pods running co-located on a compute node. This access could include access to all secrets, pods, environment variables, running pod/container processes, and persistent volumes, including in privileged containers.
