Enemies Of Symfony (EOS)

EOS loots information from a Symfony target in debug mode:

Section	Description
General	Get general information about the target.
Phpinfo	Extract Symfony environment variables from the exposed phpinfo().
Routes	Get the list of registered routes.
Request logs	Look for credentials in POST request logs.
Project files	Retrieve project files (configuration, database, etc.) based on a wordlist.
Sources	Extract the application source code.
Cookies	Craft Remember Me cookies.

Note that this tool does not exploit any Symfony vulnerability. The profiler is a useful component for developers and EOS simply takes advantage on misconfigured Symfony applications. In fact, the profiler documentation prominently warns developers:

Never enable the profiler in production environments as it will lead to major security vulnerabilities in your project.

Thanks to all the Symfony team for their awesome work!
