中文标题:
Cisco Identity Services Engine 安全漏洞
英文标题:
Cisco Identity Services Engine Radius Suppression Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Identity Services Engine（Cisco 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（Cisco ISE）存在安全漏洞，该漏洞源于处理RADIUS访问请求时存在逻辑错误，可能导致拒绝服务。
英文描述:
A vulnerability in the RADIUS setting Reject RADIUS requests from clients with repeated failures on Cisco Identity Services Engine (ISE) could allow an unauthenticated, remote attacker to cause Cisco ISE to restart unexpectedly. This vulnerability is due to a logic error when processing a RADIUS access request for a MAC address that is already a rejected endpoint. An attacker could exploit this vulnerability by sending a specific sequence of multiple crafted RADIUS access request messages to Cisco ISE. A successful exploit could allow the attacker to cause a denial of service (DoS) condition when Cisco ISE restarts.
