A vulnerability in the MPLS Operation, Administration, and Maintenance (OAM) feature of Cisco NX-OS Software for Cisco Nexus 3000 Series Switches and Cisco Nexus 9000 Series Switches could allow an unauthenticated, remote attacker to execute arbitrary code with root privileges or cause a denial of service (DoS) condition on an affected device.

This vulnerability is due to improper validation when an affected device is processing an MPLS echo-request packet. An attacker could exploit this vulnerability by sending a crafted MPLS echo-request to an IP address on an affected device. A successful exploit could allow the attacker to execute arbitrary code with root privileges and could cause process crashes, which could result in a device reload and a DoS condition.
