CVE-2020-3200

A vulnerability in the Secure Shell (SSH) server code of Cisco IOS Software and Cisco IOS XE Software could allow an authenticated, remote attacker to cause an affected device to reload. The vulnerability is due to an internal state not being represented correctly in the SSH state machine, which leads to an unexpected behavior. An attacker could exploit this vulnerability by creating an SSH connection to an affected device and using a specific traffic pattern that causes an error condition within that connection. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition.

Una vulnerabilidad en el código del servidor Secure Shell (SSH) de Cisco IOS Software y el Cisco IOS XE Software, podría permitir a un atacante remoto autenticado causar una recarga de un dispositivo afectado. La vulnerabilidad es debido a que un estado interno no está representado correctamente en la maquina de estado SSH, lo que conlleva a un comportamiento inesperado. Un atacante podría explotar esta vulnerabilidad al crear una conexión SSH en un dispositivo afectado y usando un patrón de tráfico específico que cause una condición de error dentro de esa conexión. Una explotación con éxito podría permitir a un atacante causar que el dispositivo se vuelva a cargar, resultando en una condición de denegación de servicio (DoS).
