漏洞描述
中文描述:

Cisco Identity Services Engine（ISE）是美国思科（Cisco）公司的一款环境感知平台（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 存在资源管理错误漏洞，该漏洞源于某些RADIUS请求处理不当。未经认证的远程攻击者可利用该漏洞导致受影响的系统停止处理RADIUS报文。

英文描述:

A vulnerability in the RADIUS feature of Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to cause the affected system to stop processing RADIUS packets. This vulnerability is due to improper handling of certain RADIUS requests. An attacker could exploit this vulnerability by attempting to authenticate to a network or a service where the access server is using Cisco ISE as the RADIUS server. A successful exploit could allow the attacker to cause Cisco ISE to stop processing RADIUS requests, causing authentication/authorization timeouts, which would then result in legitimate requests being denied access. Note: To recover the ability to process RADIUS packets, a manual restart of the affected Policy Service Node (PSN) is required. See the Details section for more information.
