Cisco Nexus Dashboard and Nexus Dashboard Fabric Controller Unauthorized REST API Vulnerabilities
Summary
-
Multiple vulnerabilities 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.
These vulnerabilities exist because of missing authorization controls on some REST API endpoints. An attacker could exploit these vulnerabilities by sending crafted API requests to an affected endpoint. A successful exploit could allow the attacker to perform limited Administrator functions, such as accessing sensitive information regarding HTTP Proxy and NTP configurations, uploading images, and damaging image files on an affected device.
Note: These vulnerabilities affect only a subset of REST API endpoints and do not affect the web-based management interface.
Cisco has released software updates that address these vulnerabilities. There are no workarounds that address these vulnerabilities.
