Descriptions
A vulnerability in the IPsec Manager of Cisco StarOS for Cisco Aggregation Services Router (ASR) 5000 Series Routers and Virtualized Packet Core (VPC) System Software could allow an unauthenticated, remote attacker to terminate all active IPsec VPN tunnels and prevent new tunnels from being established, resulting in a denial of service (DoS) condition. The vulnerability is due to improper processing of corrupted Internet Key Exchange Version 2 (IKEv2) messages. An attacker could exploit this vulnerability by sending crafted IKEv2 messages toward an affected router. A successful exploit could allow the attacker to cause the ipsecmgr service to reload. A reload of this service could cause all IPsec VPN tunnels to be terminated and prevent new tunnels from being established until the service has restarted, resulting in a DoS condition. This vulnerability affects the following Cisco products when they are running Cisco StarOS: Cisco Aggregation Services Router (ASR) 5000 Series Routers, Virtualized Packet Core (VPC) System Software. Cisco Bug IDs: CSCve29605.
Una vulnerabilidad en IPsec Manager en Cisco StarOS para Cisco Aggregation Services Router (ASR) 5000 Series Routers y Virtualized Packet Core (VPC) System Software podría permitir que un atacante remoto no autenticado termine todos los túneles VPN IPsec y evite que se establezcan nuevos túneles. Esto resultaría en una condición de denegación de servicio (DoS). La vulnerabilidad se debe al procesamiento incorrecto de mensajes Internet Key Exchange Version 2 (IKEv2) corruptos. Un atacante podría explotar esta vulnerabilidad enviando mensajes IKEv2 manipulados a un dispositivo afectado. Su explotación con éxito podría permitir que el atacante consiga que el servicio ipsecmgr se vuelva a cargar. Una recarga de este servicio podría provocar que todos los túneles VPN IPsec se terminen y que no se puedan crear otros hasta que el servicio se reinicie, lo que desemboca en una condición de denegación de servicio (DoS). Esta vulnerabilidad afecta a los siguientes productos de Cisco que ejecutan el software Cisco StarOS: Cisco Aggregation Services Router (ASR) 5000 Series Routers y Virtualized Packet Core (VPC) System Software. Cisco Bug IDs: CSCve29605.
