Technical Description
A vulnerability in an API endpoint of Cisco Application Policy Infrastructure Controller (APIC) and Cisco Cloud Application Policy Infrastructure Controller (Cloud APIC) could allow an authenticated, remote attacker with Administrator read-only credentials to elevate privileges on an affected system. This vulnerability is due to an insufficient role-based access control (RBAC). An attacker with Administrator read-only credentials could exploit this vulnerability by sending a specific API request using an app with admin write credentials. A successful exploit could allow the attacker to elevate privileges to Administrator with write privileges on the affected device.
