CVE-2023-20183Network attack vector

User information disclosure via unauthorized API request

Published May 18, 2023 · Updated Oct 25, 2024

Improper authorization in the Cisco Catalyst Center API allows remote authenticated users to enumerate limited user information. The API processes a specific user-information request without enforcing the authorization required to restrict the returned account data. Low-privileged access is sufficient, and disclosure is limited to configured-user details without passwords or password hashes.
