Lukas Reschke cc8c0b6a90 Check if request is sent from official ownCloud client
There are authentication backends such as Shibboleth that do send no Basic Auth credentials for DAV requests. This means that the ownCloud DAV backend would consider these requests coming from an untrusted source and require higher levels of security checks. (e.g. a CSRF check)

While an elegant solution would rely on authenticating via token (so that one can properly ensure that the request came indeed from a trusted client) this is a okay'ish workaround for this problem until we have something more reliable in the authentication code.

Lukas Reschke a977465af5 Add new CSRF manager for unit testing purposes
This adds a new CSRF manager for unit testing purposes, it's interface is based upon https://github.com/symfony/security-csrf. Due to some of our required custom changes it is however not possible to use the Symfony component directly.

Otherwise an empty string is used indicating the cookie is only valid for those resources. This can lead to eunexpected behaviour.

Lukas Reschke 8313a3fcb3 Add mitigation against BREACH
While BREACH requires the following three factors to be effectively exploitable we should add another mitigation:

1. Application must support HTTP compression
2. Response most reflect user-controlled input
3. Response should contain sensitive data

Especially part 2 is with ownCloud not really given since user-input is usually only echoed if a CSRF token has been passed.

To reduce the risk even further it is however sensible to encrypt the CSRF token with a shared secret. Since this will change on every request an attack such as BREACH is not feasible anymore against the CSRF token at least.

There are cases where no trusted host is specified such as when installing the instance, this lead to an undefined offset warning in the log right after installing. (when another domain than localhost or 127.0.0.1 was used)

Lukas Reschke bbd5f28415 Let users configure security headers in their Webserver
Doing this in the PHP code is not the right approach for multiple reasons:

1. A bug in the PHP code prevents them from being added to the response.
2. They are only added when something is served via PHP and not in other cases (that makes for example the newest IE UXSS which is not yet patched by Microsoft exploitable on ownCloud)
3. Some headers such as the Strict-Transport-Security might require custom modifications by administrators. This was not possible before and lead to buggy situations.

This pull request moves those headers out of the PHP code and adds a security check to the admin settings performed via JS.

Bernhard Posselt 95239ad21e AppFramework StreamResponse
First stab at the StreamResponse, see #12988

The idea is to use an interface ICallbackResponse (I'm not 100% happy with the name yet, suggestions?) that allow the response to output things in its own way, for instance stream the file using readfile

Unittests are atm lacking, plan is to

check if a mock of ICallbackResponse will be used by calling its callback (also unhappy with this name) method
Usage is:

$response = new StreamResponse('path/to/file');

rename io to output, add additional methods and handle error and not modified cases when using StreamResponse

fix indention and uppercasing, also handle forbidden cases

fix indention

fix indention

no forbidden, figuring out if a file is really readable is too complicated to get to work across OSes and streams

Lukas Reschke 886bda5f81 Refactor OC_Request into TrustedDomainHelper and IRequest
This changeset removes the static class `OC_Request` and moves the functions either into `IRequest` which is accessible via `\OC::$server::->getRequest()` or into a separated `TrustedDomainHelper` class for some helper methods which should not be publicly exposed.

This changes only internal methods and nothing on the public API. Some public functions in `util.php` have been deprecated though in favour of the new non-static functions.

Unfortunately some part of this code uses things like `__DIR__` and thus is not completely unit-testable. Where tests where possible they ahve been added though.

Lukas Reschke 770fa761b8 Respect `mod_unique_id` and refactor `OC_Request::getRequestId`
When `mod_unique_id` is enabled the ID generated by it will be used for logging. This allows for correlation of the Apache logs and the ownCloud logs.

Testplan:

- [ ] When `mod_unique_id` is enabled the request ID equals the one generated by `mod_unique_id`.
- [ ] When `mod_unique_id` is not available the request ID is a 20 character long random string
- [ ] The generated Id is stable over the lifespan of one request

Changeset looks a little bit larger since I had to adjust every unit test using the HTTP\Request class for proper DI.

Lukas Reschke 048139074d Add functions to modify cookies to response class
Currently there is no AppFramework way to modify cookies, which makes it unusable for quite some use-cases or results in untestable code.

This PR adds some basic functionalities to add and invalidate cookies.

Usage:
```php
$response = new TemplateResponse(...);
$response->addCookie('foo', 'bar');
$response->invalidateCookie('foo');
$response->addCookie('bar', 'foo', new \DateTime('2015-01-01 00:00'));
```

Existing cookies can be accessed with the AppFramework using `$this->request->getCookie($name)`.
