Description
A flaw was found in 389 Directory Server. An unauthenticated remote attacker can inject LDAP search filters into the CleanAllRUV replication status-check extended operation. Because the handler performs the search against cn=config with elevated replication plugin privileges and returns a boolean match result, the attacker can extract sensitive server configuration metadata, including replication bind DNs and password storage scheme information.
