Descriptions

Improper validation of URL redirection in the Kubernetes API server in versions prior to v1.14.0 allows an attacker-controlled Kubelet to redirect API server requests from streaming endpoints to arbitrary hosts. Impacted API servers will follow the redirect as a GET request with client-certificate credentials for authenticating to the Kubelet.

Una comprobación inapropiada de un redireccionamiento de URL en el servidor Kubernetes API en versiones anteriores a v1.14.0, permite que un Kubelet controlado por el atacante redireccione las peticiones del servidor API desde endpoints de transmisión hacia hosts arbitrarios. Los servidores API impactados seguirán el redireccionamiento como una petición GET con credenciales de certificado del cliente para autenticarse en el Kubelet.
