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!
Tested on Python >= 3.7.
