Title: Cisco Security Advisory - Cisco Meeting Server Call Bridge Denial of Service Vulnerability
Post by: Netwörkheäd on December 22, 2021, 12:08:36 PM
Cisco Meeting Server Call Bridge Denial of Service Vulnerability

A vulnerability in an API of the Call Bridge feature of Cisco Meeting Server could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition.


This vulnerability is due to improper handling of large series of message requests. An attacker could exploit this vulnerability by sending a series of messages to the vulnerable API. A successful exploit could allow the attacker to cause the affected device to reload, dropping all ongoing calls and resulting in a DoS condition.


Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
