Descriptions

A vulnerability in the logging configuration of Secure Sockets Layer (SSL) policies for Cisco FirePOWER System Software 5.3.0 through 6.2.2 could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition due to high consumption of system resources. The vulnerability is due to the logging of certain TCP packets by the affected software. An attacker could exploit this vulnerability by sending a flood of crafted TCP packets to an affected device. A successful exploit could allow the attacker to cause a DoS condition. The success of an exploit is dependent on how an administrator has configured logging for SSL policies for a device. This vulnerability affects Cisco FirePOWER System Software that is configured to log connections by using SSL policy default actions. Cisco Bug IDs: CSCvd07072.

Una vulnerabilidad en la configuración del registro de las políticas de Secure Sockets Layer (SSL) para FirePOWER System Software versiones 5.3.0 hasta 6.2.2 de Cisco, podría permitir a un atacante no autenticado remoto causar una denegación de servicio (DoS) debido al alto consumo de recursos del sistema . La vulnerabilidad es debido al registro de ciertos paquetes TCP por parte del programa afectado. Un atacante podría explotar esta vulnerabilidad mediante el envió de una avalancha de paquetes TCP diseñados hacia un dispositivo afectado. Una explotación con éxito podría permitir al atacante causar una condición DoS. El éxito de una explotación depende de cómo un administrador ha configurado el registro para las políticas SSL para un dispositivo. Esta vulnerabilidad afecta a FirePOWER System Software de Cisco que está configurado para registrar conexiones mediante el uso de acciones por defecto de la política SSL. IDs de Bug de Cisco: CSCvd07072.
