Description
A vulnerability in the log4jinit web application of Cisco Unified Communications Manager (UCM) could allow an unauthenticated, remote attacker to access the log4jinit web application.

The vulnerability is due to insufficient authentication checking when accessing the log4jinit web application. An attacker could exploit this vulnerability by accessing the log4jinit web application. An exploit could allow the attacker to generate activity in the log4jinit web application and cause performance issues for users currently logged into the Cisco UCM command line.

Cisco has confirmed the vulnerability in a security notice; however, software updates are not available.
 
Warning Indicators
At the time this alert was first published, Cisco UCM versions 10.0(1) and prior were vulnerable. Later releases of Cisco UCM may also be vulnerable.
 
IntelliShield Analysis
To exploit this vulnerability, it is likely that an attacker would need access to trusted, internal networks and the ability to locate an affected device, which may require footprinting the network. These access requirements could limit the possibility of a successful exploit.
