Cisco IoT Field Network Director Missing API Authentication (cisco-sa-FND-APIA-xZntFS2V)

high Nessus Plugin ID 143231

Language:

Synopsis

The remote device is missing a vendor-supplied security patch

Description

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 sending API requests to an affected system, to view sensitive information on the affected system, including information about the devices that the system manages, without authentication.

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

Solution

Upgrade to the relevant fixed version referenced in Cisco bug ID CSCvt45296
