VAR-201904-0243

Vulnerability from variot - Updated: 2023-12-18 12:00

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. This issue is being tracked by Cisco Bug IDCSCvn99036. The Cisco Expressway Series is an advanced collaboration gateway for unified communications. The vulnerability is caused by the network system or product not properly validating the input data
