Descriptions
A vulnerability in the web-based management interface of Cisco SD-WAN vManage Software could allow an authenticated, remote attacker to consume excessive system memory and cause a denial of service (DoS) condition on an affected system. The vulnerability is due to inefficient memory management. An attacker could exploit this vulnerability by sending a large number of crafted HTTP requests to the affected web-based management interface. A successful exploit could allow the attacker to exhaust system memory, which could cause the system to stop processing new connections and could result in a DoS condition.
Una vulnerabilidad en la interfaz de administración basada en web de Cisco SD-WAN vManage Software podría permitir a un atacante remoto autenticado consumir memoria excesiva del sistema y causar una condición de denegación de servicio (DoS) sobre un sistema afectado. La vulnerabilidad es debido a una gestión de memoria ineficiente. Un atacante podría explotar esta vulnerabilidad mediante el envío de una gran cantidad de peticiones HTTP diseñadas a la interfaz de administración basada en web afectada. Una explotación con éxito podría permitir a un atacante agotar la memoria del sistema, lo que podría causar que el sistema deje de procesar nuevas conexiones y podría resultar en una condición DoS
