Descriptions

A design flaw issue was found in the Red Hat OpenStack Platform director use of TripleO to enable libvirtd based live-migration. Libvirtd is deployed by default (by director) listening on 0.0.0.0 (all interfaces) with no-authentication or encryption. Anyone able to make a TCP connection to any compute host IP address, including 127.0.0.1, other loopback interface addresses, or in some cases possibly addresses that have been exposed beyond the management interface, could use this to open a virsh session to the libvirtd instance and gain control of virtual machine instances or possibly take over the host.

Se ha detectado un fallo de diseño en el director de Red Hat OpenStack Platform que utiliza TripleO para permitir migraciones live basadas en libvirtd. Libvirtd se implementa por defecto (por el director) escuchando en 0.0.0.0 (todas las interfaces) sin ninguna autenticación o cifrado. Cualquiera que sea capaz de hacer una conexión TCP a cualquier dirección IP del host, incluyendo 127.0.0.1, otras direcciones de interfaz loopback o, en algunos casos, posibles direcciones que hayan sido expuestas más allá de la interfaz de administración, podría utilizar esto para abrir una sesión virsh en la instancia libvirtd y obtener el control de las instancias de la máquina virtual o posiblemente tomar el control del host.
