CVE-2019-1747

Estado: ModificadaAlta (8.6)—

A vulnerability in the implementation of the Short Message Service (SMS) handling functionality of Cisco IOS Software and Cisco IOS XE Software could allow an unauthenticated, remote attacker to trigger a denial of service (DoS) condition on an affected device. The vulnerability is due to improper processing of SMS protocol data units (PDUs) that are encoded with a special character set. An attacker could exploit this vulnerability by sending a malicious SMS message to an affected device. A successful exploit could allow the attacker to cause the wireless WAN (WWAN) cellular interface module on an affected device to crash, resulting in a DoS condition that would require manual intervention to restore normal operating conditions.

Un atacante podría explotar esta vulnerabilidad enviando un mensaje SMS manipulado a un dispositivo afectado. Su explotación con éxito podría permitir que el atacante provoque que el módulo de la interfaz del celular de WAN inalámbrica (WWAN) en un dispositivo afectado se cierre inesperadamente, lo que resulta en una DoS que requeriría una intervención manual para restaurar las condiciones de operación normales."
