Onapsis Security Advisory – It is possible for an unauthenticated user to remove audit events from a remote BusinessObjects service using CORBA. Specifically, the attacker can tell the remote service (i.e. the auditee) to clear an event from it’s queue. After the event is removed from the auditee queue, the auditor will never have knowledge of the event and, hence, it will not be written to the Audit database. An attacker can use this to hide their actions. By default, the auditor polls all auditees every 5 minutes to ask for events in their queue.
