CVE-2022-20714

A vulnerability in the data plane microcode of Lightspeed-Plus line cards for Cisco ASR 9000 Series Aggregation Services Routers could allow an unauthenticated, remote attacker to cause the line card to reset. This vulnerability is due to the incorrect handling of malformed packets that are received on the Lightspeed-Plus line cards. An attacker could exploit this vulnerability by sending a crafted IPv4 or IPv6 packet through an affected device. A successful exploit could allow the attacker to cause the Lightspeed-Plus line card to reset, resulting in a denial of service (DoS) condition for any traffic that traverses that line card.

Una vulnerabilidad en el microcódigo del plano de datos de las tarjetas de línea Lightspeed-Plus para Cisco ASR 9000 Series Aggregation Services Routers podría permitir a un atacante remoto no autenticado causar el reinicio de la tarjeta de línea. Esta vulnerabilidad es debido al manejo incorrecto de paquetes malformados que son recibidos en las tarjetas de línea Lightspeed-Plus. Un atacante podría aprovechar esta vulnerabilidad mediante el envío de un paquete IPv4 o IPv6 diseñado mediante un dispositivo afectado. Una explotación con éxito podría permitir al atacante causar el reinicio de la tarjeta de línea Lightspeed-Plus, resultando en una condición de negación de servicio (DoS) para cualquier tráfico que salta esa tarjeta de línea
