CVE-2019-14837Public exploitNetwork attack vector

Unauthenticated service-account takeover via placeholder email

Published Jan 7, 2020 · Updated Aug 5, 2024

Authentication bypass in Red Hat build of Keycloak before 8.0.0 allows remote attackers to take over service accounts via password reset. ClientManager.enableServiceAccount and clientIdChanged assign each service account a predictable [email protected] address rather than leaving email unset. Control of placeholder.org mail and knowledge of a client name are sufficient to reset credentials and log in with that service account.
