CVE-2012-6431
First published: Mon Mar 19 2012(Updated: )
On the Symfony 2.0.x version, there's a security issue that allows access to routes protected by a firewall even when the user is not logged in. Both the Routing component and the Security component uses the path returned by `getPathInfo()` to match a Request. The `getPathInfo()` returns a decoded path, but the Routing component (`Symfony\Component\Routing\Matcher\UrlMatcher`) decodes the path a second time; whereas the Security component, `Symfony\Component\HttpFoundation\RequestMatcher`, does not. This difference causes Symfony 2.0 to be vulnerable to double encoding attacks.
