CVE-2021-22002Network attack vector

Unauthenticated internal service access via Host header

Published Aug 31, 2021 · Updated Aug 3, 2024

Improper authentication in VMware Workspace ONE Access and Identity Manager allows remote attackers to reach restricted /cfg services. A crafted Host header makes the port 443 front end route requests to the /cfg web application and diagnostic endpoints normally exposed on port 8443. Network access to port 443 is sufficient, and diagnostic endpoints are reachable without authentication, exposing restricted internal service functionality.
