Descriptions

A vulnerability in the host input API daemon of Cisco Firepower Management Center (FMC) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to improper certificate validation. An attacker could exploit this vulnerability by sending a crafted data stream to the host input daemon of the affected device. A successful exploit could allow the attacker to cause the host input daemon to restart. The attacker could use repeated attacks to cause the daemon to continuously reload, creating a DoS condition for the API.

Una vulnerabilidad en el demonio de la API de entrada del host de Cisco Firepower Management Center (FMC) Software podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) en un dispositivo afectado. La vulnerabilidad es debido a una comprobación inapropiada del certificado. Un atacante podría explotar esta vulnerabilidad mediante el envío de un flujo de datos diseñado al demonio de entrada del host del dispositivo afectado. Una explotación con éxito podría permitir a un atacante causar que el demonio de entrada del host se reinicie. El atacante podría usar ataques repetidos para causar que el demonio se recargue continuamente, creando una condición de DoS para la API
