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. 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.

Weakness

The code transmits data to another actor, but a portion of the data includes sensitive information that should not be accessible to that actor.

Potential Mitigations

  • Compartmentalize the system to have “safe” areas where trust boundaries can be unambiguously drawn. Do not allow sensitive data to go outside of the trust boundary and always be careful when interfacing with a compartment outside of the safe area.
  • Ensure that appropriate compartmentalization is built into the system design, and the compartmentalization allows for and reinforces privilege separation functionality. Architects and designers should rely on the principle of least privilege to decide the appropriate time to use privileges and the time to drop privileges.
