Symfony Security Configuration Exposure

What is the "Symfony Security Configuration Exposure?"

The "Symfony Security Configuration Exposure" module is designed to detect misconfigurations in the security configuration of Symfony applications. It targets Symfony, a popular PHP framework known for its robust security features. This module has an informative severity level, meaning it provides valuable information about potential security risks without indicating an immediate vulnerability. The original author of this module is dahse89.

Impact

This module helps identify potential security risks in the security configuration of Symfony applications. By detecting misconfigurations, it allows developers to address these issues and enhance the overall security of their applications. It provides insights into areas such as firewalls and access control, which are crucial for protecting sensitive data and preventing unauthorized access.

How does the module work?

The "Symfony Security Configuration Exposure" module works by sending HTTP requests to specific paths, such as "/config/packages/security.yaml" and "/app/config/security.yml". It then applies matching conditions to the responses received from these requests to determine if the security configuration is exposed. The matching conditions include checking the HTTP status code (200) and searching for specific keywords in the response body, such as "security:", "firewalls:", and "access_control:". If these conditions are met, the module identifies a potential misconfiguration.

Here is an example of an HTTP request sent by the module:

GET /config/packages/security.yaml

The module matches the response against the following conditions:

- The HTTP status code must be 200. - The response body must contain the keywords "security:", "firewalls:", and "access_control:".

If both conditions are satisfied, the module reports the potential exposure of the Symfony security configuration.
