漏洞描述
中文描述:

Cisco 4000 Series Integrated Services Routers是美国思科（Cisco）公司的一款4000系列企业级多业务路由器。IOS XE是使用在其中的一个为Cisco网络设备开发的操作系统。 Cisco 4000 Series Integrated Services Routers中的IOS XE的存在信息泄露漏洞。攻击者可利用该漏洞通过未认证的ISDN连接发送IPv4流量。

英文描述:

A vulnerability in the Dialer interface feature for ISDN connections in Cisco IOS XE Software for Cisco 4000 Series Integrated Services Routers (ISRs) could allow an unauthenticated, adjacent attacker to pass IPv4 traffic through an ISDN channel prior to successful PPP authentication. The vulnerability is due to insufficient validation of the state of the PPP IP Control Protocol (IPCP). An attacker could exploit this vulnerability by making an ISDN call to an affected device and sending traffic through the ISDN channel prior to successful PPP authentication. Alternatively, an unauthenticated, remote attacker could exploit this vulnerability by sending traffic through an affected device that is configured to exit via an ISDN connection for which both the Dialer interface and the Basic Rate Interface (BRI) have been configured, but the Challenge Handshake Authentication Protocol (CHAP) password for PPP does not match the remote end. A successful exploit could allow the attacker to pass IPv4 traffic through an unauthenticated ISDN connection for a few seconds, from initial ISDN call setup until PPP authentication fails.
