漏洞描述
中文描述:

Cisco IOS XE是美国思科(Cisco)公司的一套为其网络设备开发的操作系统。 Cisco IOS XE中的Network Address Translation (NAT) Session Initiation Protocol (SIP) Application Layer Gateway (ALG)存在资源管理错误漏洞,该漏洞源于程序没有正确处理临时的SIP数据包。远程攻击者可借助UDP 5060端口发送特制的SIP数据包利用该漏洞造成设备重新加载,导致拒绝服务。以下产品及版本受到影响:Cisco 1100, 4200, and 4300 Integrated Services Routers (ISRs);Cloud Services Router (CSR) 1000V Series;Enterprise Network Compute System (ENCS);Integrated Services Virtual Router (ISRv)。

英文描述:

A vulnerability in the Network Address Translation (NAT) Session Initiation Protocol (SIP) Application Layer Gateway (ALG) of Cisco IOS XE Software could allow an unauthenticated, remote attacker to cause an affected device to reload. The vulnerability is due to improper processing of transient SIP packets on which NAT is performed on an affected device. An attacker could exploit this vulnerability by using UDP port 5060 to send crafted SIP packets through an affected device that is performing NAT for SIP packets. A successful exploit could allow an attacker to cause the device to reload, resulting in a denial of service (DoS) condition.
