CVE-2023-20086

A vulnerability in ICMPv6 processing of Cisco Adaptive Security Appliance (ASA) Software and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition. This vulnerability is due to improper processing of ICMPv6 messages. An attacker could exploit this vulnerability by sending crafted ICMPv6 messages to a targeted Cisco ASA or FTD system with IPv6 enabled. A successful exploit could allow the attacker to cause the device to reload, resulting in a DoS condition.

Una vulnerabilidad en el procesamiento ICMPv6 del software Cisco Adaptive Security Appliance (ASA) y el software Cisco Firepower Threat Defense (FTD) podría permitir que un atacante remoto no autenticado provoque una condición de Denegación de Servicio (DoS). Esta vulnerabilidad se debe a un procesamiento inadecuado de mensajes ICMPv6. Un atacante podría aprovechar esta vulnerabilidad enviando mensajes ICMPv6 manipulados a un sistema Cisco ASA o FTD objetivo con IPv6 habilitado. Un exploit exitoso podría permitir que el atacante provoque que el dispositivo se recargue, lo que resultaría en una condición DoS.
