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 Video Communication Server 中存在安全漏洞。该漏洞源于传入 SIP 流量处理不正确。攻击者可以通过向受影响的设备发送一系列 SIP 数据包来利用此漏洞。成功的利用可能允许攻击者耗尽受影响设备上的内存，导致内存崩溃并导致 DoS 情况。
英文描述:
A vulnerability in the Session Initiation Protocol (SIP) of Cisco Expressway Series and Cisco TelePresence Video Communication Server (VCS) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to incorrect handling of incoming SIP traffic. An attacker could exploit this vulnerability by sending a series of SIP packets to an affected device. A successful exploit could allow the attacker to exhaust memory on an affected device, causing it to crash and leading to a DoS condition.
