英文标题:
Cisco IOS XE Software MACsec MKA Using EAP-TLS Authentication Bypass Vulnerability
漏洞描述
中文描述:
Cisco IOS XE Software是美国思科(Cisco)公司的一套为其网络设备开发的操作系统。 Cisco IOS XE Software中的MACsec Key Agreement (MKA) using Extensible Authentication Protocol-Transport Layer Security (EAP-TLS)功能存在访问控制错误漏洞,该漏洞源于受影响的软件中存在逻辑错误。攻击者可通过连接Layer 3接口并发送流量利用该漏洞绕过802.1x网络访问控制,获取网络的访问权限。
英文描述:
A vulnerability in the MACsec Key Agreement (MKA) using Extensible Authentication Protocol-Transport Layer Security (EAP-TLS) functionality of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to bypass authentication and pass traffic through a Layer 3 interface of an affected device. The vulnerability is due to a logic error in the affected software. An attacker could exploit this vulnerability by connecting to and passing traffic through a Layer 3 interface of an affected device, if the interface is configured for MACsec MKA using EAP-TLS and is running in access-session closed mode. A successful exploit could allow the attacker to bypass 802.1x network access controls and gain access to the network.
