漏洞描述
中文描述:

Cisco Nexus 3000 Series Switches等都是美国思科（Cisco）公司的产品。Cisco Nexus 3000 Series Switches是一款3000系列交换机。Cisco Nexus 3500 Platform Switches是一款3500系列平台交换机。Cisco Nexus 9000 Series Switches是一款9000系列交换机。Cisco NX-OS Software是一套交换机使用的数据中心级操作系统软件。 Cisco NX-OS Software中的802.1X实现存在权限许可和访问控制漏洞，该漏洞源于程序没有执行完整的输入验证机制。攻击者可利用该漏洞造成设备重启，导致拒绝服务。以下产品和版本受到影响：Cisco Nexus 1000V Switch for VMware vSphere 5.2(1)SV3(1.4b)之前版本；Nexus 3000 Series Switches 7.0(3)I7(4)之前版本；Nexus 3500 Platform Switches 7.0(3)I7(4)之前版本；Nexus 2000 Series Switches 7.3(5)N1(1)之前版本，7.1(5)N1(1b)之前版本；Nexus 5500 Series Switches 7.3(5)N1(1)之前版本，7.1(5)N1(1b)之前版本；Nexus 5600 Series Switches 7.3(5)N1(1)之前版本，7.1(5)N1(1b)之前版本；Nexus 6000 Series Switches 7.3(5)N1(1)之前版本，7.1(5)N1(1b)之前版本；Nexus 7000 Series Switches 8.2(3)之前版本；Nexus 7700 Series Switches 8.2(3)之前版本；Nexus 9000 Series Fabric Switches in ACI Mode 13.2(1l)之前版本；Nexus 9000 Series Switches in Standalone NX-OS Mode 7.0(3)I7(4)之前版本。

英文描述:

A vulnerability in the 802.1X implementation for Cisco NX-OS Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to incomplete input validation of Extensible Authentication Protocol over LAN (EAPOL) frames. An attacker could exploit this vulnerability by sending a crafted EAPOL frame to an interface on the targeted device. A successful exploit could allow the attacker to cause the Layer 2 (L2) forwarding process to restart multiple times, leading to a system-level restart of the device and a DoS condition. Note: This vulnerability affects only NX-OS devices configured with 802.1X functionality. Cisco Nexus 1000V Switch for VMware vSphere devices are affected in versions prior to 5.2(1)SV3(1.4b). Nexus 3000 Series Switches are affected in versions prior to 7.0(3)I7(4). Nexus 3500 Platform Switches are affected in versions prior to 7.0(3)I7(4). Nexus 2000, 5500, 5600, and 6000 Series Switches are affected in versions prior to 7.3(5)N1(1) and 7.1(5)N1(1b). Nexus 7000 and 7700 Series Switches are affected in versions prior to 8.2(3). Nexus 9000 Series Fabric Switches in ACI Mode are affected in versions prior to 13.2(1l). Nexus 9000 Series Switches in Standalone NX-OS Mode are affected in versions prior to 7.0(3)I7(4).
