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存在安全漏洞，该漏洞源于某些RADIUS记帐请求处理不当，可能允许未经身份验证的远程攻击者导致受影响的系统停止处理RADIUS数据包。
英文描述:
A vulnerability in the RADIUS message processing 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 accounting requests. An attacker could exploit this vulnerability by sending a crafted authentication request to a network access device (NAD) that uses Cisco ISE for authentication, authorization, and accounting (AAA). This would eventually result in the NAD sending a RADIUS accounting request packet to Cisco ISE. An attacker could also exploit this vulnerability by sending a crafted RADIUS accounting request packet to Cisco ISE directly if the RADIUS shared secret is known. A successful exploit could allow the attacker to cause the RADIUS process to unexpectedly restart, resulting in authentication or authorization timeouts and denying legitimate users access to the network or service. Clients already authenticated to the network would not be affected. Note: To recover the ability to process RADIUS packets, a manual restart of the affected Policy Service Node (PSN) may be required. For more information, see the Details ["#details"] section of this advisory.
