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.
