Cisco IoT Field Network Director Unauthenticated REST API (cisco-sa-FND-BCK-GHkPNZ5F)

Critical Nessus Plugin ID 143234

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: 5.9


The remote device is missing a vendor-supplied security patch


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.
