Symfony Enabled Debug Mode Scanner

One of the main features of debug mode is the display of detailed error pages. If your app raises an exception when debug is True, Symfony will display a detailed traceback, including a lot of metadata about your environment, such as all the currently defined Symfony settings. If an attacker can successfully start a remote debugging session, this is likely to disclose sensitive information about the web application and supporting infrastructure that may be valuable in formulating targeted attacks against the system.
