Descriptions
Multiple vulnerabilities in the payload inspection for Ethernet Industrial Protocol (ENIP) traffic for Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to bypass configured rules for ENIP traffic. These vulnerabilities are due to incomplete processing during deep packet inspection for ENIP packets. An attacker could exploit these vulnerabilities by sending a crafted ENIP packet to the targeted interface. A successful exploit could allow the attacker to bypass configured access control and intrusion policies that should be activated for the ENIP packet.
Múltiples vulnerabilidades en la inspección de la carga útil del tráfico del Protocolo Industrial Ethernet (ENIP) para el software Cisco Firepower Threat Defense (FTD) podrían permitir a un atacante remoto no autenticado omitir las reglas configuradas para el tráfico ENIP. Estas vulnerabilidades son debido al procesamiento incompleto durante la inspección profunda de paquetes para los paquetes ENIP. Un atacante podría explotar estas vulnerabilidades enviando un paquete ENIP diseñado a la interfaz objetivo. Una explotación con éxito podría permitir al atacante omitir el control de acceso configurado y las políticas de intrusión que deberían activarse para el paquete ENIP
