Descriptions

Cisco IOS XR on ASR 9000 devices does not properly use compression for port-range and address-range encoding, which allows remote attackers to bypass intended Typhoon line-card ACL restrictions via transit traffic, aka Bug ID CSCup30133.

Cisco IOS XR en los dispositivos ASR 9000 no utiliza debidamente la compresión para la codificación de los rangos de puertos y los rangos de direcciones, lo que permite a atacantes remotos evadir las restricciones ACL de la tarjeta de línea Typhoon a través de trafico de transito, también conocido como Bug ID CSCup30133.
