CWE-600: Uncaught Exception in Servlet
The Servlet does not catch all exceptions, which may reveal sensitive debugging information.
How it's found
Uncaught Exception in Servlet is a specific, narrowly defined instance of a broader pattern. Testers confirm it with targeted code review and a proof-of-concept input that exercises the exact code path this weakness describes.
When a Servlet throws an exception, the default error response the Servlet container sends back to the user typically includes debugging information. This information is of great value to an attacker. For example, a stack trace might show the attacker a malformed SQL query string, the type of database being used, and the version of the application container. This information enables the attacker to target known vulnerabilities in these components.
Consequences
- Read Application Data, DoS: Crash, Exit, or Restart
Mitigations
- Implementation: Implement Exception blocks to handle all types of Exceptions.
