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.
Affected products named by the advisory: Red Hat Directory Server 11; Red Hat Directory Server 12; Red Hat Directory Server 13; Red Hat Enterprise Linux 10; and 3 more.
Affected products named by the advisory: Red Hat Enterprise Linux 7; Red Hat Enterprise Linux 8; Red Hat Enterprise Linux 9.
