"A Rest API vulnerability exists in Cisco IoT Field Network Director (IoT-FND) due to IoT-FND not properly authenticating
REST API calls. An unauthenticated, remote attacker can exploit this, by obtaining a cross-site request forgery (CSRF)
token and then using the token with REST API requests, to access the back-end database of the affected device and
read, alter, or drop information.

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
