CVE-2022-20921Network attack vector

Authenticated Administrator escalation via improperly authorized API requests

Published Aug 25, 2022 · Updated Nov 1, 2024

Improper authorization in Cisco ACI Multi-Site Orchestrator 3.1 before 3.1(1n) allows remote authenticated users to become administrators. Specific API endpoints accept crafted HTTP requests from non-Administrator accounts without enforcing the authorization required for Administrator operations. The prerequisite is a non-Administrator account with API reachability; successful exploitation grants Administrator privileges on the affected device.
