Description

A vulnerability in the REST API endpoints of Cisco Nexus Dashboard and Cisco Nexus Dashboard Fabric Controller (NDFC) could allow an authenticated, low-privileged, remote attacker to view sensitive information or upload and modify files on an affected device.

This vulnerability exists because of missing authorization controls on some REST API endpoints. An attacker could exploit th vulnerability by sending crafted API requests to an affected endpoint.
