Descriptions
A vulnerability in the processing of SSH connections of Cisco Firepower Management Center (FMC) and Cisco Firepower Threat Defense (FTD) Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device.
This vulnerability is due to improper error handling when an SSH session fails to be established. An attacker could exploit this vulnerability by sending a high rate of crafted SSH connections to the instance. A successful exploit could allow the attacker to cause resource exhaustion, resulting in a reboot on the affected device.
Una vulnerabilidad en el procesamiento de conexiones SSH de Cisco Firepower Management Center (FMC) y el software Cisco Firepower Threat Defense (FTD) podría permitir que un atacante remoto no autenticado cause una condición de Denegación de Servicio (DoS) en un dispositivo afectado. Esta vulnerabilidad se debe a un manejo inadecuado de errores cuando no se puede establecer una sesión SSH. Un atacante podría aprovechar esta vulnerabilidad enviando una alta tasa de conexiones SSH manipuladas a la instancia. Un exploit exitoso podría permitir que el atacante provoque el agotamiento de los recursos, lo que provocaría un reinicio en el dispositivo afectado.
