Interscan Viruswall is a mail gateway solution distributed and maintained by Trend Micro. This problem affects versions running on the Microsoft Windows platform. Viruswall does not preserve headers from email when it is passed from Viruswall to the MTA running on the system. This problem makes it possible for outside users to obscure the origins of mail sent to the server. An attacker could take advantage of this vulnerability to spam the host without the risk of being traced. This vulnerability could also be exploited to send misinformation through the host, appearing to come from a user of the mail system.
