Descriptions

A vulnerability in the syslog processing engine of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a race condition that may occur when syslog messages are processed. An attacker could exploit this vulnerability by sending a high rate of syslog messages to an affected device. A successful exploit could allow the attacker to cause the Application Server process to crash, resulting in a DoS condition.

Una vulnerabilidad en el motor de procesamiento de syslog de Cisco Identity Services Engine (ISE), podría permitir a un atacante remoto no autenticado causar una condición de denegación de servicio (DoS) sobre un dispositivo afectado. La vulnerabilidad es debido a una condición de carrera que puede ocurrir cuando los mensajes syslog son procesados. Un atacante podría explotar esta vulnerabilidad mediante el envío de una alta tasa de mensajes syslog hacia un dispositivo afectado. Una explotación con éxito podría permitir al atacante causar que el proceso Application Server se bloquee, resultando en una condición DoS.
