root.
Date: 8/1/2002
Application: Apache Tomcat Java server versions 3.23 and
3.24
Platform: Linux/Unix
Severity: Remote attackers can obtain the location of
webroot
Authors: Richard Brain [richard.brain@procheckup.com]
Vendor Status:
CVE Candidate: Not assigned
Reference: www.procheckup.com
Description:
Tomcat is the free opensource Java server,
http://jakarta.apache.org/tomcat/.
A example program is provided with tomcat under the
http://webserver/test directory which gives the location of
the webroot.
The test page of "http://webserver/test"; displays the
following message :-
"This is the home page of the test hierarchy. It doesn't do
too much good to look at it directly... Instead, why don't
you run the tests to find out what you might want to know.
Oh, by the way, merry christmas.. :)"
The vulnerabilities may only work on port 8080 rather than
port 80, dependant on how the webserver has been configured
with Tomcat.
A) Requesting the following url :-
http://webserver/test/realPath.jsp
Displays the following:-
The virtual path is /test/realPath.jsp
The real path is "WEBROOT"/test/test/realPath.jsp
The real path is "WEBROOT"/test/realPath.jsp
Solution:
Delete the realPath.jsp program.
