The Domino server has been configured to allow anonymous access to the ScanMail Time Database (/smtime.nsf). This database is used by TrendMicro's ScanMail for Lotus Notes to control and schedule ScanMail's handling of attachments. The database can be used to limit the size of attachments sent during business hours (i.e. to control bandwidth during peak usage hours, forcing large attachments to be resent during off-peak hours). An attacker could use this database to inspect and disable these limitations, which would then allow him to bypass your restrictions. Under no circumstances should non-Administrative users have access to this database.
