Summary

Netsparker identified a stack trace disclosure (Grails) in the target web server's HTTP response.

Impact
An attacker can obtain information such as:
  • Stack trace.
  • Information about the generated exception.
This information might help an attacker gain more information and potentially focus on the development of further attacks for the target system.
Remediation
Configure your application not to provide detailed error pages in production environments. Save all information regarding the error to a backend storage, such as a log or a text file, and show a friendly custom error page to the user.
