CVE-2022-32557Network attack vector

Unauthenticated Index Service access via missing authentication

Published Jun 14, 2022 · Updated Aug 3, 2024

Missing authentication in the Index Service in Couchbase Server before 7.0.4 allows remote attackers to connect via TCP/TLS without credentials. The Index Service listeners accept network requests without authenticating the connecting client, although public sources do not identify the responsible handler or protocol messages. Network reachability to an Index Service listener is sufficient; public sources do not identify which index operations become available.
