Cisco Unified Communications Domain Manager High CPU Utilization Vulnerability

http://tools.cisco.com/security/center/content/CiscoSecurityNotice/CVE-2013-1230

CVE ID: CVE-2013-1230

Release Date: 2013 April 30 09:55 UTC (GMT)

Last Updated: 2013 April 30 09:55 UTC (GMT)

Summary

A vulnerability in the network stack of Cisco Unified Communications Domain 
Manager could allow an unauthenticated, remote attacker to cause high CPU 
utilization on the affected system.

The vulnerability is due to insufficient optimization of resources when the 
affected system is flooded with malformed UDP packets. An attacker could 
exploit this vulnerability by sending malformed UDP packets to the affected 
system. An exploit could allow the attacker to cause high CPU utilization 
during the attack. CPU utilization returns to a normal value when the attack 
is terminated.
