漏洞描述
中文描述:
Cisco Identity Services Engine（ISE）是美国思科（Cisco）公司的一款基于身份的环境感知平台（ISE身份服务引擎）。该平台通过收集网络、用户和设备中的实时信息，制定并实施相应策略来监管网络。 Cisco Identity Services Engine 2.2.0.470-Patch13之前版本、2.3.0.298-Patch6之前版本和2.4.0.357-Patch2之前版本中的syslog处理引擎存在竞争条件问题漏洞。攻击者可通过向受影响的设备发送大量Syslog消息利用该漏洞导致Application Server进程崩溃，进而导致拒绝服务。
英文描述:
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.
