Cisco NX-OS Software for Nexus 5500, 5600, and 6000 Series Switches Precision Time Protocol Denial of Service Vulnerability
A vulnerability in the Precision Time Protocol (PTP) feature of Cisco Nexus 5500, 5600, and 6000 Series Switches running Cisco NX-OS Software could allow an unauthenticated, remote attacker to cause a denial of service (DoS) condition on an affected device. The vulnerability is due to a lack of protection against PTP frame flood attacks. An attacker could exploit this vulnerability by sending large streams of malicious IPv4 or IPv6 PTP traffic to the affected device. A successful exploit could allow the attacker to cause a DoS condition, impacting the traffic passing through the device. Cisco has released software updates that address this vulnerability. There are no workarounds that address this vulnerability.
