Description

A vulnerability in the SSL/TLS implementation of Cisco Nexus Dashboard Orchestrator (NDO) could allow an unauthenticated, remote attacker to intercept sensitive information from an affected device. 

This vulnerability exists because the Cisco NDO Validate Peer Certificate site management feature validates the certificates for Cisco Application Policy Infrastructure Controller (APIC), Cisco Cloud Network Controller (CNC), and Cisco Nexus Dashboard only when a new site is added or an existing one is reregistered. An attacker could exploit this vulnerability by using machine-in-the-middle techniques to intercept the traffic between the affected device and Cisco NDO and then using a crafted certificate to impersonate the affected device. A successful exploit could allow the attacker to learn sensitive information during communications between these devices.

CVSS v3 base metrics

Attack vector: More severe the more the remote (logically and physically) an attacker can be in order to exploit the vulnerability.
Attack complexity: More severe for the least complex attacks.
Privileges required: More severe if no privileges are required.
User interaction: More severe when no user interaction is required.
Scope: More severe when a scope change occurs, e.g. one vulnerable component impacts resources in components beyond its security scope.
Confidentiality: More severe when loss of data confidentiality is highest, measuring the level of data access available to an unauthorized user.
Integrity: More severe when loss of data integrity is the highest, measuring the consequence of data modification possible by an unauthorized user.
Availability: More severe when the loss of impacted component availability is highest.
