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中的XML API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 XML API 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 specifically crafted XML payload. A successful exploit could allow the attacker to exhaust CPU resources, resulting in a DoS condition until the system is manually rebooted. Software versions prior to X12.5.1 are affected.
