Summary:
Ref T4593. Via HackerOne. An attacker can use the anchor reattachment, combined with the Facebook token workflow, combined with redirection on OAuth errors to capture access tokens. The attack works roughly like this:
- Create an OAuth application on Phabricator.
- Set the domain to `evil.com`.
- Grab the OAuth URI for it (something like `https://phabricator.com/oauthserver/auth/?redirect_uri=http://evil.com&...`).
- Add an invalid `scope` parameter (`scope=xyz`).
- Use //that// URI to build a Facebook OAuth URI (something like `https://facebook.com/oauth/?redirect_uri=http://phabricator.com/...&response_type=token`).
- After the user authorizes the application on Facebook (or instantly if they've already authorized it), they're redirected to the OAuth server, which processes the request. Since this is the 'token' workflow, it has auth information in the URL anchor/fragment.
- The OAuth server notices the `scope` error and 302's to the attacker's domain, preserving the anchor in most browsers through anchor reattachment.
- The attacker reads the anchor in JS and can do client workflow stuff.
To fix this, I've made several general changes/modernizations:
- Add a new application and make it beta. This is mostly cleanup, but also turns the server off for typical installs (it's not generally useful quite yet).
- Add a "Console" page to make it easier to navigate.
- Modernize some of the UI, since I was touching most of it anyways.
Then I've made specific security-focused changes:
- In the web-based OAuth workflow, send back a human-readable page when errors occur. I //think// this is universally correct. Previously, humans would get a blob of JSON if they entered an invalid URI, etc. This type of response is correct for the companion endpoint ("ServerTokenController") since it's called by programs, but I believe not correct for this endpoint ("AuthController") since it's used by humans. Most of this is general cleanup (give humans human-readable errors instead of JSON blobs).
- Never 302 off this endpoint automatically. Previously, a small set of errors (notably, bad `scope`) would cause a 302 with 'error'. This exposes us to anchor reattachment, and isn't generally helpful to anyone, since the requesting application did something wrong and even if it's prepared to handle the error, it can't really do anything better than we can.
- The only time we'll 'error' back now from this workflow is if a user explicitly cancels the workflow. This isn't a 302, but a normal link (the cancel button), so the anchor is lost.
- Even if the application is already approved, don't blindly 302. Instead, show the user a confirmation dialog with a 'continue' link. This is perhaps slightly less user-friendly than the straight redirect, but I think it's pretty reasonable in general, and it gives us a lot of protection against these classes of attack. This redirect is then through a link, not a 302, so the anchor is again detached.

Summary:
Ref T4593. There are a variety of clever attacks against OAuth which involve changing the redirect URI to some other URI on the same domain which exhibits unexpected behavior in response to an OAuth request. The best approach to dealing with this is for providers to lock to a specific path and refuse to redirect elsewhere, but not all providers do this.
We haven't had any specific issues related to this, but the anchor issue in T4593 was only a step away.
To mitigate this in general, we can reject the OAuth2 `'code'` parameter on //every// page by default, and then whitelist it on the tiny number of controllers which should be able to receive it.
This is very coarse, kind of overkill, and has some fallout (we can't use `'code'` as a normal parameter in the application), but I think it's relatively well-contained and seems reasonable. A better approach might be to whitelist parameters on every controller (i.e., have each controller specify the parameters it can receive), but that would be a ton of work and probably cause a lot of false positives for a long time.
Since we don't use `'code'` normally anywhere (as far as I can tell), the coarseness of this approach seems reasonable.
Test Plan:
- Logged in with OAuth.
- Hit any other page with `?code=...` in the URL, got an exception.
- Grepped for `'code'` and `"code"`, and examined each use to see if it was impacted.

Two behavioral changes:
- If the redirect URI for an application is "https", require HTTPS always.
- According to my reading of http://tools.ietf.org/html/draft-ietf-oauth-v2-23#section-3.1.2 we need to check both names //and values// for parameters. Add value checking. I think this makes more sense in general? No one uses this, soooo...

We've been building a Jenkins plugin that allows you to use your Phabricator login details in Jenkins using the inbuilt OAuthServer. I noticed that when making a request to /oauthserver/auth/?client_id=&response_type=code I get an error back from the server.
I've traced this down to two bugs in PhabricatorOAuthServerAuthController, the first causes a null value error on $access_token_uri, and the second fails on userHasAuthorizedClient without a $scope array.

We are removing the headers for these reasons:
- It wastes space in editors, less code is visible in editor upon opening a file.
- It brings noise to diff of the first change of any file every year.
- It confuses Git file copy detection when creating small files.
- We don't have an explicit license header in other files (JS, CSS, images, documentation).
- Using license header in every file is not obligatory: http://www.apache.org/dev/apply-license.html#new.

Summary:
I'm trying to make progress on the policy/visibility stuff since it's a blocker for Wikimedia.
First, I want to improve Projects so they can serve as policy groups (e.g., an object can have a visibility policy like "Visible to: members of project 'security'"). However, doing this without breaking anything or snowballing into a bigger change is a bit awkward because Projects are name-ordered and we have a Conduit API which does offset paging. Rather than breaking or rewriting this stuff, I want to just continue offset paging them for now.
So I'm going to make PhabricatorPolicyQuery extend PhabricatorOffsetPagedQuery, but can't currently since the `executeWithPager` methods would clash. These methods do different things anyway and are probably better with different names.
This also generally improves the names of these classes, since cursors are not necessarily IDs (in the feed case, they're "chronlogicalKeys", for example). I did leave some of the interals as "ID" since calling them "Cursor"s (e.g., `setAfterCursor()`) seemed a little wrong -- it should maybe be `setAfterCursorPosition()`. These APIs have very limited use and can easily be made more consistent later.
Test Plan: Browsed around various affected tools; any issues here should throw/fail in a loud/obvious way.

Summary:
This diff makes the OAuthServer more compliant with the spec by
- making it return well-formatted error codes with error types from the spec.
- making it respect the "state" variable, which is a transparent variable the
client passes and the server passes back
- making it be super, duper compliant with respect to redirect uris
-- if specified in authorization step, check if its valid relative to the client
registered URI and if so save it
-- if specified in authorization step, check if its been specified in the access
step and error if it doesn't match or doesn't exist
-- note we don't make any use of it in the access step which seems strange but
hey, that's what the spec says!
This diff makes the OAuthServer suck less by
- making the "cancel" button do something in the user authorization flow
- making the client list view and client edit view be a bit more usable around
client secrets
- fixing a few bugs I managed to introduce along the way
Test Plan:
- create a test phabricator client, updated my conf, and then linked and
unlinked phabricator to itself
- wrote some tests for PhabricatorOAuthServer -- they pass!
-- these validate the various validate URI checks
- tried a few important authorization calls
--

--- verified error'd from mismatching redirect uri's
--- verified state parameter in response

specified
-- http://phabricator.dev/oauthserver/auth/?client_id=X&response_type=code w/

--- got redirected to proper client url with pertinent code!
- tried a few important access calls
-- verified appropriate errors if missing any required parameters
-- verified good access code with appropriate other variables resulted in an

for scope
Summary:
this patch makes the access token response "complete" relative to spec by
returning when it expires AND that the token_type is in fact 'Bearer'.
This patch also lays the groundwork for scope by fixing the underlying data
model and adding the first scope checks for "offline_access" relative to expires
and the "whoami" method. Further, conduit is augmented to open up individual
methods for access via OAuth generally to enable "whoami" access. There's also
a tidy little scope class to keep track of all the various scopes we plan to
have as well as strings for display (T849 - work undone)
Somewhat of a hack but Conduit methods by default have SCOPE_NOT_ACCESSIBLE. We
then don't even bother with the OAuth stuff within conduit if we're not supposed
to be accessing the method via Conduit. Felt relatively clean to me in terms
of additional code complexity, etc.
Next up ends up being T848 (scope in OAuth) and T849 (let user's authorize
clients for specific scopes which kinds of needs T850). There's also a bunch of
work that needs to be done to return the appropriate, well-formatted error
codes. All in due time...!
Test Plan:
verified that an access_token with no scope doesn't let me see
anything anymore. :( verified that access_tokens made awhile ago expire. :(

Summary:
adds a Phabricator OAuth server, which has three big commands:
- auth - allows $user to authorize a given client or application. if $user has already authorized, it hands an authoization code back to $redirect_uri
- token - given a valid authorization code, this command returns an authorization token
- whoami - Conduit.whoami, all nice and purdy relative to the oauth server.
Also has a "test" handler, which I used to create some test data. T850 will
delete this as it adds the ability to create this data in the Phabricator
product.
This diff also adds the corresponding client in Phabricator for the Phabricator
OAuth Server. (Note that clients are known as "providers" in the Phabricator
codebase but client makes more sense relative to the server nomenclature)
Also, related to make this work well
- clean up the diagnostics page by variabilizing the provider-specific
information and extending the provider classes as appropriate.
- augment Conduit.whoami for more full-featured OAuth support, at least where
the Phabricator client is concerned
What's missing here... See T844, T848, T849, T850, and T852.
Test Plan:
- created a dummy client via the test handler. setup development.conf to have
have proper variables for this dummy client. went through authorization and
de-authorization flows
- viewed the diagnostics page for all known oauth providers and saw
provider-specific debugging information
