# Subject: KPMG-2002033: Resin DOS device path disclosure
# Date: Wed, 17 Jul 2002 11:33:59 +0200

desc = "
Resin will reveal the physical path of the webroot 
when asked for a special DOS device, e.g. lpt9.xtp

An attacker may use this flaw to gain further knowledge
about the remote filesystem layout.

Solution : Upgrade to a later software version.

Risk factor : Low";
