  Jigsaw Webserver Path Disclosure
------------------------------------------------------------------------

SUMMARY

 <http://www.w3.org> Jigsaw is W3C's leading-edge Web server platform,
providing a sample HTTP 1.1 implementation and a variety of other features
on top of an advanced architecture implemented in Java. It is possible to
disclose the physical path to the web root. This information could be
useful to a malicious user wishing to gain illegal access to resources on
the server.

DETAILS

Vulnerable systems:
 * Jigsaw version 2.2.1 Distribution on Windows 2000 Server

Immune systems:
 * Jigsaw version 2.2.1 Dev/2.2/20020711 on Windows 2000 Server

Requesting /aux two times, results in an error message, after second
request, containing the physical path to the web root.

Vendor response:
The vendor was notified on 27 May 2002. On 11 July 2002, we verified that
the issue was corrected in the latest build (20020708).
