Descriptions

The Cisco Umbrella Virtual Appliance Version 2.0.3 and prior contained an undocumented encrypted remote support tunnel (SSH) which auto initiated from the customer's appliance to Cisco's SSH Hubs in the Umbrella datacenters. These tunnels were primarily leveraged for remote support and allowed for authorized/authenticated personnel from the Cisco Umbrella team to access the appliance remotely and obtain full control without explicit customer approval. To address this vulnerability, the Umbrella Virtual Appliance version 2.1.0 now requires explicit customer approval before an SSH tunnel from the VA to the Cisco terminating server can be established.

Cisco Umbrella Virtual Appliance en sus versiones 2.0.3 y anteriores contenían un túnel de soporte remoto cifrado sin documentar (SSH) que se iniciaba automáticamente desde la máquina del cliente a los hubs SSH de Cisco en los CPD de Umbrella. Estos túneles se utilizaban en principio para proporcionar soporte remoto y permitían al personal autorizado/autenticado del equipo de Cisco Umbrella para que accediesen a la máquina remotamente y obtuvieses el control total sin la aprobación explícita del cliente. Para resolver esta vulnerabilidad, la versión 2.1.0 de Umbrella Virtual Appliance ahora necesita la aprobación explícita del cliente antes de que se pueda establecer un túnel SSH desde la máquina virtual al servidor destino de Cisco.
