Extended Description

A Web application must define a default error page for 4xx errors (e.g. 404), 5xx (e.g. 500) errors and catch java.lang.Throwable exceptions to prevent attackers from mining information from the application container's built-in error response.

When an attacker explores a web site looking for vulnerabilities, the amount of information that the site provides is crucial to the eventual success or failure of any attempted attacks.

Example Vulnerable Codes

Example - 1

In the snippet below, an unchecked runtime exception thrown from within the try block may cause the container to display its default error page (which may contain a full stack trace, among other things).

...logger.error("Caught: " + ase.toString());try {} catch (ApplicationSpecificException ase) {}Public void doPost(HttpServletRequest request, HttpServletResponse response) throws ServletException, IOException {}
