Descriptions

In Kubernetes versions 1.3.x, 1.4.x, 1.5.x, 1.6.x and prior to versions 1.7.14, 1.8.9 and 1.9.4 containers using a secret, configMap, projected or downwardAPI volume can trigger deletion of arbitrary files/directories from the nodes where they are running.

En Kubernetes, en versiones 1.3.x, 1.4.x, 1.5.x, 1.6.x y en versiones anteriores a la 1.7.14, 1.8.9 y 1.9.4, los contenedores que emplean un volumen secreto, configMap, proyectado o downwardAPI pueden desencadenar la eliminación de archivos/directorios arbitrarios de los nodos en los que se están ejecutando.

This vulnerability allows containers using a secret, configMap, projected, or downwardAPI volume to trigger deletion of arbitrary files and directories on the nodes where they are running. An attacker could use this flaw to delete arbitrary file or directories on node host.
