CVE-2013-6701

Name of the Vulnerable Software and Affected Versions Cisco ONS 15454 devices with software versions prior to 9.6

Description The issue is related to the tNetTaskLimit process on the Transport Node Controller (TNC) which does not properly prioritize health pings. This allows remote attackers to cause a denial of service, resulting in a watchdog timeout and TNC reset, via a flood of network traffic.
