漏洞描述
中文描述:
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 IPv6 VPN存在安全漏洞。攻击者利用该漏洞可以重新加载设备，从而导致拒绝服务情况。
英文描述:
A vulnerability in the implementation of IPv6 VPN over MPLS (6VPE) with Zone-Based Firewall (ZBFW) of Cisco IOS XE Software could allow an unauthenticated, adjacent attacker to cause a denial of service (DoS) condition on an affected device. This vulnerability is due to improper error handling of an IPv6 packet that is forwarded from an MPLS and ZBFW-enabled interface in a 6VPE deployment. An attacker could exploit this vulnerability by sending a crafted IPv6 packet sourced from a device on the IPv6-enabled virtual routing and forwarding (VRF) interface through the affected device. A successful exploit could allow the attacker to reload the device, resulting in a DoS condition.
