漏洞描述
中文描述:

Cisco Expressway Series和Cisco TelePresence Video Communication Server(VCS)都是美国思科(Cisco)公司的产品。Cisco Expressway Series是一款用于统一通信的高级协作网关。Cisco TelePresence Video Communication Server是一款视频通信服务器。 Cisco Expressway Series和Cisco TelePresence VCS X12.5.1之前版本中的电话簿功能存在输入验证错误漏洞,该漏洞源于网络系统或产品未对输入的数据进行正确的验证。

英文描述:

A vulnerability in the phone book feature of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an authenticated, remote attacker to cause the CPU to increase to 100% utilization, causing a denial of service (DoS) condition on an affected system. The vulnerability is due to improper handling of the XML input. An attacker could exploit this vulnerability by sending a Session Initiation Protocol (SIP) message with a crafted XML payload to an affected device. A successful exploit could allow the attacker to exhaust CPU resources, resulting in a DoS condition. Manual intervention may be required to recover the device. This vulnerability is fixed in Cisco Expressway Series and Cisco TelePresence Video Communication Server Releases X12.5.1 and later.
