The vulnerability is due to insufficient internal security measures in the OAC feature. An attacker could exploit this vulnerability by crafting specific packets for communication on the device-internal network. A successful exploit could allow the attacker to run code on the underlying host operating system. OAC is not enabled by default. For a device to be vulnerable, an administrator would need to install and activate this feature. This vulnerability affects the following Cisco Nexus Series Switches: Nexus 2000 Series Fabric Extenders, Nexus 5000 Series Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches, Nexus 6000 Series Switches, Nexus 7000 Series Switches, Nexus 7700 Series Switches.
