CVE-2018-0476 (CNNVD-201809-1254)
中文标题:
Cisco IOS XE Software NAT SIP ALG 资源管理错误漏洞
英文标题:
Cisco IOS XE Software NAT Session Initiation Protocol Application Layer Gateway Denial of Service Vulnerability
漏洞描述
中文描述:
Cisco IOS XE Software是美国思科(Cisco)公司的一套为其网络设备开发的操作系统。Network Address Translation(NAT)Session Initiation Protocol(SP)Application Layer Gateway(ALG)是其中的一个网关组件。 Cisco IOS XE Software中的NAT SIP ALG存在资源管理错误漏洞,该漏洞源于在执行NAT时,程序没有正确的处理传输中的SIP数据包。远程攻击者可通过向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。
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 SIP packets in transit while NAT is performed on an affected device. An unauthenticated, remote attacker could exploit this vulnerability by sending crafted SIP packets via UDP port 5060 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.
