"A vulnerability in the NX API (NX-API) Sandbox interface for Cisco NX-
OS Software could allow an authenticated, remote attacker to conduct a
cross-site scripting (XSS) attack against a user of the NX-API Sandbox
interface of an affected device. The vulnerability is due to
insufficient validation of user-supplied input by the NX-API Sandbox
interface. An attacker could exploit this vulnerability by persuading
a user of the NX-API Sandbox interface to click a crafted link. A
successful exploit could allow the attacker to execute arbitrary
script code in the context of the affected NX-API Sandbox interface.

This plugin only works with Tenable.ot.
