MailDepot version 2032 SP2 (2.2.1242) suffers from an improper authorization vulnerability. The REDDOXX MailDepot web service does not correctly verify whether a user has the proper rights to access specified mailboxes in a corresponding web service request. The web service request will only be processed if it contains a valid authentication token (usual REST web service), but the names of the mailboxes to be accessed are given within a JSON object which is not validated properly regarding user access permissions. Thus, any authenticated user can access mailboxes of other users due to improper authorization checks.
