"The remote OT asset is affected by a vulnerability.");
  script_set_attribute(attribute:"description", value:
"A vulnerability in the NX-API management application programming
interface (API) in devices running, or based on, Cisco NX-OS Software
could allow an authenticated, remote attacker to execute commands with
elevated privileges. The vulnerability is due to a failure to properly
validate certain parameters included within an NX-API request. An
attacker that can successfully authenticate to the NX-API could submit
a request designed to bypass NX-OS role assignment. A successful
exploit could allow the attacker to execute commands with elevated
privileges. This vulnerability affects the following if configured to
use the NX-API feature: MDS 9000 Series Multilayer Switches, Nexus
2000 Series Switches, Nexus 3000 Series Switches, Nexus 3500 Platform
Switches, Nexus 5500 Platform Switches, Nexus 5600 Platform Switches,
Nexus 6000 Series Switches, Nexus 7000 Series Switches, Nexus 7700
Series Switches, Nexus 9000 Series Switches in standalone NX-OS mode.
Cisco Bug IDs: CSCvc73177, CSCve40903, CSCve40911.

This plugin only works with Tenable.ot.
