Summary
Acunetix 360 detected that the web application displays detailed error messages that disclose the server version and detailed stack trace information.
It's recommended to modify the configuration file WEB-INF/web.xml to display custom error pages, preventing the information leakage.
Impact
The detailed error messages contain potentially sensitive information that might help an attacker to conduct further attacks.
Actions To Take
Using the following configuration an error page will be displayed whenever the application responds with an HTTP 500 error. You can add additional entries for other HTTP status codes as well:
<error-page>
<error-code>500</error-code>
<location>/path/to/error.jsp</location>
</error-page>
