--------------------------------------------------------------------

Title: Apache Tomcat Path Disclosure

BUG-ID: 2002024
Released: 19th Jun 2002
--------------------------------------------------------------------

Problem:
========
It is possible to disclose the physical path to the webroot. This
information could be useful to a malicious user wishing to gain
illegal access to resources on the server.


Vulnerable:
===========
- Apache Tomcat 4.0.3 on Windows 2000 Server


Not Vulnerable:
===============
- Apache Tomcat 4.1.3 beta on Windows 2000 Server


Details:
========
A request for eg. LPT9 results in a java error, which contains
the physical path to the webroot:

"java.io.FileNotFoundException: C:\Program Files\Apache Tomcat
 4.0\webapps\ROOT\lpt9 (The system cannot find the file specified)"


Vendor URL:
===========
You can visit the vendor webpage here: http://jakarta.apache.org


Vendor Response:
================
This was reported to the vendor on the 23rd of May, 2002. We
never heard back from the vendor. On the 10th of June, 2002, the
issue was confirmed fixed in the latest build.


Corrective action:
==================
Upgrade to V4.1.3 beta, which is available here (URL is wrapped):

"http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release
/v4.1.3-beta/"
