Description

A vulnerability in the API endpoints for Cisco DNA Center could allow an authenticated, remote attacker to gain access to sensitive information that should be restricted. The attacker must have valid device credentials. This vulnerability is due to improper access controls on API endpoints. An attacker could exploit the vulnerability by sending a specific API request to an affected application. A successful exploit could allow the attacker to obtain sensitive information about other users who are configured with higher privileges on the application.

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.
CVSS:3.1/AV:N/AC:L/PR:L/UI:N/S:U/C:L/I:N/A:N
