漏洞描述
中文描述:

Cisco Nexus 9300-FX3 Series是美国思科(Cisco)公司的一系列交换机。 Cisco Nexus 9300-FX3 Series Fabric Extender (FEX) 存在安全漏洞,该漏洞源于密码验证功能实现不当。攻击者利用该漏洞绕过身份验证,导致设备重启和拒绝服务情况。

英文描述:

A vulnerability in the CLI console login authentication of Cisco Nexus 9300-FX3 Series Fabric Extender (FEX) when used in UCS Fabric Interconnect deployments could allow an unauthenticated attacker with physical access to bypass authentication. This vulnerability is due to the improper implementation of the password validation function. An attacker could exploit this vulnerability by logging in to the console port on an affected device. A successful exploit could allow the attacker to bypass authentication and execute a limited set of commands local to the FEX, which could cause a device reboot and denial of service (DoS) condition.
