英文标题:
Cisco Nexus 9000 Series Fabric Switches ACI Mode Multi-Pod and Multi-Site TCP Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco Nexus 9000 Series Fabric Switches是美国思科(Cisco)公司的一款9000系列光纤交换机。 Cisco Nexus 9000 Series Fabric Switches 存在数据伪造问题漏洞,该漏洞源于发送到受影响设备上特定端口的 TCP 流量未正确清理。该漏洞可能允许未经身份验证的远程攻击者意外重启设备,从而导致拒绝服务 (DoS)。
英文描述:
A vulnerability in the Multi-Pod or Multi-Site network configurations for Cisco Nexus 9000 Series Fabric Switches in Application Centric Infrastructure (ACI) mode could allow an unauthenticated, remote attacker to unexpectedly restart the device, resulting in a denial of service (DoS) condition. This vulnerability exists because TCP traffic sent to a specific port on an affected device is not properly sanitized. An attacker could exploit this vulnerability by sending crafted TCP data to a specific port that is listening on a public-facing IP address for the Multi-Pod or Multi-Site configuration. A successful exploit could allow the attacker to cause the device to restart unexpectedly, resulting in a DoS condition.
