"According to its self-reported version, Cisco NX-OS Software is affected by following 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.
