  Apache Tomcat Path Disclosure
------------------------------------------------------------------------

SUMMARY

A security vulnerability in Apache's Tomcat makes it is possible to
disclose the physical path of the webroot. This information could be
useful to a malicious user wishing to gain illegal access to resources on
the server.

DETAILS

Vulnerable systems:
 - Apache Tomcat 4.0.3 on Windows 2000 Server

Immune systems:
 - Apache Tomcat 4.1.3 beta on Windows 2000 Server

A request for e.g. 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 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/>
http://jakarta.apache.org/builds/jakarta-tomcat-4.0/release/v4.1.3-beta/
