漏洞描述
中文描述:
Cisco NX-OS Software是美国思科（Cisco）公司的一套交换机使用的数据中心级操作系统软件。 Cisco NX-OS Software 存在安全漏洞，攻击者利用该漏洞导致受影响设备拒绝服务。
英文描述:
A vulnerability in the implementation of the system login block-for command for Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a login process to unexpectedly restart, causing a denial of service (DoS) condition. This vulnerability is due to a logic error in the implementation of the system login block-for command when an attack is detected and acted upon. An attacker could exploit this vulnerability by performing a brute-force login attack on an affected device. A successful exploit could allow the attacker to cause a login process to reload, which could result in a delay during authentication to the affected device.
