New! Vulnerability Priority Rating (VPR)

Tenable calculates a dynamic VPR for every vulnerability. VPR combines vulnerability information with threat intelligence and machine learning algorithms to predict which vulnerabilities are most likely to be exploited in attacks. Read more about what VPR is and how it's different from CVSS.

VPR Score: 6.3


The remote device is missing a vendor-supplied security patch


An authorization bypass vulnerability exists in Cisco IoT Field Network Director (IoT-FND) due to insufficient authorization in the SOAP API. An authenticated, remote attacker can exploit this, via SOAP API requests, to bypass authorization and access and modify information on devices that belong to a different domain.

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