Descriptions

Cloud Foundry Routing Release, all versions prior to 0.188.0, contains a vulnerability that can hijack the traffic to route services hosted outside the platform. A user with space developer permissions can create a private domain that shadows the external domain of the route service, and map that route to an app. When the gorouter receives traffic destined for the external route service, this traffic will instead be directed to the internal app using the shadow route.

Cloud Foundry Routing Release, todas las versiones anteriores a 0.188.0, contiene una vulnerabilidad que puede secuestrar el tráfico para enrutar los servicios alojados fuera de la plataforma. Un usuario con permisos de desarrollador de espacio puede crear un dominio privado que oculte el dominio externo del servicio de ruta y asignar esa ruta hacia una aplicación. Cuando el gorouter recibe el tráfico destinado al servicio de ruta externo, este tráfico se direccionará a la aplicación interna usando la ruta oculta.
