An attacker could exploit this vulnerability by sending a large and sustained number of crafted remote management connections to an affected device, resulting in a buildup of those connections over time. A successful exploit could allow the attacker to cause the remote management interface or Cisco Firepower Device Manager (FDM) to stop responding and cause other management functions to go offline, resulting in a DoS condition. The user traffic that is flowing through the device would not be affected, and the DoS condition would be isolated to remote management only."}, {"lang": "es", "value": "Una vulnerabilidad en como el Cisco Firepower Threat Defense (FTD) Software maneja los tiempos de espera de sesi\u00f3n para las conexiones de administraci\u00f3n, podr\u00eda permitir a un atacante remoto no autenticado causar una acumulaci\u00f3n de conexiones de administraci\u00f3n remota en un dispositivo afectado, lo que podr\u00eda resultar en una condici\u00f3n de denegaci\u00f3n de servicio (DoS).
