CVE-2020-3353


TITLE

Cisco Identity Services Engine Race condition vulnerabilities in

Trust: 0.8

sources: JVNDB: JVNDB-2020-006325

DESCRIPTION

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. The platform monitors the network by collecting real-time information on the network, users and devices, and formulating and implementing corresponding policies
