SV-33032r1_rule Java software on production web servers must be limited to class files and the JAVA virtual machine.

Vulnerability discussion

From the source code in a .java or a .jpp file, the Java compiler produces a binary file with an extension of .class. The .java or .jpp file would, therefore, reveal sensitive information regarding an application’s logic and permissions to resources on the server. By contrast, the .class file, because it is intended to be machine independent, is referred to as bytecode. Bytecodes are run by the Java Virtual Machine (JVM), or the Java Runtime Environment (JRE), via a browser configured to permit Java code.

Check content

Enter the commands: find / -name *.java find / -name *.jpp If either file type is found, this is a finding.

Fix text

Remove the unnecessary files from the web server.

Pro Tips

Lavender hyperlinks in small type off to the right (of CSS class id, if you view the page source) point to globally unique URIs for each document and item. Copy the link location and paste anywhere you need to talk unambiguously about these things.

You can obtain data about documents and items in other formats. Simply provide an HTTP header Accept: text/turtle or Accept: application/rdf+xml.
