This isn't a proof of concept, but more a probe for misconfigured database ACL's. If a Domino web server doesn't have a redirection URL for /mail/* mail files, then you rely on the access control for each mail file. Two things can be done to avoid this : 1 - Change the ACL on sensitive databases ( /mail/* , names.nsf ) to : Anonymous - No access [Default] - No access 2 - Within the Server Document for each server, ensure that "Allow HTTP clients to browse databases:" is set to "No" I believe that all versions of Domino server from 4.5 upwards are suceptible to badly configured ACL's. Any good administrator would have a hold of this already. #!/usr/local/bin/php -q <? <snip> </snip> fclose ($fd); ?>
