CWE-382J2EE Bad Practices: Use of System.exit()
Category: other
Description
A J2EE application uses System.exit(), which also shuts down its container.
It is never a good idea for a web application to attempt to shut down the application container. Access to a function that can shut down the application is an avenue for Denial of Service (DoS) attacks.
Common consequences· 1
- Availability — DoS: Crash, Exit, or Restart
Potential mitigations· 4
- [Architecture and Design]The shutdown function should be a privileged function available only to a properly authorized administrative user
- [Implementation]Web applications should not call methods that cause the virtual machine to exit, such as System.exit()
- [Implementation]Web applications should also not throw any Throwables to the application server as this may adversely affect the container.
- [Implementation]Non-web applications may have a main() method that contains a System.exit(), but generally should not call System.exit() from other locations in the code
