Descriptions
The kubectl cp command allows copying files between containers and the user machine. To copy files from a container, Kubernetes creates a tar inside the container, copies it over the network, and kubectl unpacks it on the user’s machine. If the tar binary in the container is malicious, it could run any code and output unexpected, malicious results. An attacker could use this to write files to any path on the user’s machine when kubectl cp is called, limited only by the system permissions of the local user. The untar function can both create and follow symbolic links. The issue is resolved in kubectl v1.11.9, v1.12.7, v1.13.5, and v1.14.0.
El comando kubectl cp permite copiar archivos entre contenedores y la máquina del usuario. Para copiar archivos de un contenedor, Kubernetes crea un alquitrán dentro del contenedor, lo copia a través de la red y kubectl lo descomprime en la máquina del usuario. Si el binario tar en el contenedor es malicioso, podría ejecutar cualquier código y generar resultados inesperados y maliciosos. Un atacante podría usar esto para escribir archivos en cualquier ruta en la máquina del usuario cuando se llama a kubectl cp, limitado solo por los permisos del sistema del usuario local. La función untar puede crear y seguir enlaces simbólicos. El problema se resuelve en kubectl v1.11.9, v1.12.7, v1.13.5 y v1.14.0.
