Cisco IOS XE Software是美国思科(Cisco)公司的一个操作系统。用于企业有线和无线访问,汇聚,核心和WAN的单一操作系统,Cisco IOS XE降低了业务和网络的复杂性。 Cisco IOS XE Software 存在安全漏洞,该漏洞允许未经身份验证的远程攻击者在受影响设备的web管理界面上造成拒绝服务(DoS)状态。
英文描述:
A vulnerability in the ingress traffic manager of Cisco IOS XE Software for Cisco Network Convergence System (NCS) 520 Routers could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition in the web management interface of an affected device. This vulnerability is due to incorrect processing of certain IPv4 TCP traffic that is destined to an affected device. An attacker could exploit this vulnerability by sending a large number of crafted TCP packets to the affected device. A successful exploit could allow the attacker to cause the web management interface to become unavailable, resulting in a DoS condition. Note: This vulnerability does not impact traffic that is going through the device or going to the Management Ethernet interface of the device.
