Title
389-ds-base: 389-ds-base: missing authorization allows anonymous clients to start or abort cleanallruv replication maintenance
Summary
A flaw was found in 389 Directory Server. The CleanAllRUV and Abort CleanAllRUV replication-maintenance extended operations perform no authorization check, allowing an unauthenticated remote attacker to invoke them when nsslapd-allow-anonymous-access is enabled (the default), or any authenticated low-privilege user to invoke them otherwise. This allows removal of a replica ID from replication metadata, purging of changelog records, and interruption of administrator-initiated cleanup, which can leave replication inconsistent or unavailable.
