Actually the issue here is running apache and tomcat within a windows env when those applications were tuned to be run on real multi-user systems rather then an env that had multi-user shoehorned in.

If any real sense of security is required do not run such applications on an architecture that has so much single user legacy built in from the ground up remaining.

Thanks,

Ron DuFresne

Well,

In my Experience, the main vulnerabilities will be found on the code
(JSP, Servlets, so on) instead of architecture (Tomcat itself).

Although Tomcat did provide a good deal of security, it still fails
due to the following method:
1.      After installation, Tomcat Runs As a System Service.
2.      If it is not run as a system service, by default all Web server
administrators run Tomcat As Administrator.
These two things allow Java Run Time to access any files in any
directory of any Windows machine. By default, Java Run Time takes the
security privileges according to the user that is running the Java Run
Time. When Tomcat is run by an administrator or as a System Service,
Java Run Time gets all the rights that the System User has or
Administrator has. In that manner, Java Run Time gets the complete
rights to all files in all directories. And, Servlets (JSP converted
to Servlets) gets the same previlleges. So, the Java code can call
File API in Java SDK to list all files in the directory, delete any
file, and also the greatest risk is to RUN a program with system
privileges. When any Servlet has code like this:

Runtime rt = Runtime.getRuntime();
rt.exec("c:\\SomeDirectory\\SomeUnsafeProgram.exe")
this is the greatest risk, and it's unknown to many people.

Hope this helps

Hi

I am looking for the way to penetrate Apache Tomcat server. Does anybody
know useful link on this? There is not much information on Web.

I need to analyze Apache Tomcat Apache Tomcat/5.5.17 server. After URI
manipulation I've found some server debug messages like this:

HTTP Status 500 - java.lang.NoSuchMethodException:
