Cisco Meeting Server H.264 Protocol Denial of Service Vulnerability
Published: 2017-08-03 03:44:03
CVE Author: NIST National Vulnerability Database
CVSS Base Vector:
AV:N/AC:L/Au:N/C:N/I:N/A:P
Detection Method:
Checks if a vulnerable version is present on the target host.
Recommendations:
See the referenced vendor advisory for a solution.
Summary:
A vulnerability in the implementation of the H.264 protocol in Cisco Meeting
Server (CMS) could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an
affected system.
Technical Details:
The vulnerability exists because the affected application does not properly
validate Fragmentation Unit (FU-A) protocol packets. An attacker could exploit this vulnerability by sending a
crafted H.264 FU-A packet through the affected application.
Impact:
A successful exploit could allow the attacker to cause a DoS condition on the
affected system due to an unexpected restart of the CMS media process on the system. Although the CMS platform
continues to operate and only the single, affected CMS media process is restarted, a brief interruption of media
traffic for certain users could occur.
Detection Type:
Remote Banner
Solution Type:
Vendor Patch

What's vulnerability management?
Vulnerability management is the process in which vulnerabilities in IT are identified and the risks of these vulnerabilities are evaluated. This evaluation leads to correcting the vulnerabilities and removing the risk or a formal risk acceptance by the management of an organization. The term vulnerability management is often confused with vulnerability scanning. Despite the fact both are related, there is an important difference between the two. Vulnerability scanning consists of using a computer program to identify vulnerabilities in networks, computer infrastructure or applications. Vulnerability management is the process surrounding vulnerability scanning, also taking into account other aspects such as risk acceptance, remediation etc. Source: "Implementing a Vulnerability Management Process".
