CVE-2023-51717Network attack vector

Unauthenticated login via accepted empty-password LDAP bind

Published Jan 9, 2024 · Updated Jun 16, 2025

Improper authentication in Dataiku DSS 11 before 11.4.5 and DSS 12 before 12.4.1 allows remote attackers to bypass LDAP login. The LDAP login path treats a successful simple Bind response as proof of credentials without rejecting an empty password, although such a bind establishes anonymous authorization. Exposure requires self-managed DSS with LDAP user authentication enabled and an LDAP server that permits unauthenticated binds; Dataiku Cloud is unaffected.
