Ref T6240. Some discussion in that task. In instance/cluster environments, daemons need to make Conduit calls that bypass policy checks.
We can't just let anyone add SSH keys with this capability to the web directly, because then an adminstrator could just add a key they own and start signing requests with it, bypassing policy checks.
Add a `bin/almanac trust-key --id <x>` workflow for trusting keys. Only trusted keys can sign requests.
Test Plan:
- Generated a user key.
- Generated a device key.
- Trusted a device key.
- Untrusted a device key.
- Hit the various errors on trust/untrust.
- Tried to edit a trusted key.

Summary:
Ref T5833. Currently, SSH keys are associated only with users, and are a bit un-modern. I want to let Almanac Devices have SSH keys so devices in a cluster can identify to one another.
For example, with hosted installs, initialization will go something like this:
- A request comes in for `company.phacility.com`.
- A SiteSource (from D10787) makes a Conduit call to Almanac on the master install to check if `company` is a valid install and pull config if it is.
- This call can be signed with an SSH key which identifies a trusted Almanac Device.
In the cluster case, a web host can make an authenticated call to a repository host with similar key signing.
To move toward this, put a proper Query class on top of SSH key access (this diff). In following diffs, I'll:
- Rename `userPHID` to `objectPHID`.
- Move this to the `auth` database.
- Provide UI for device/key association.
An alternative approach would be to build some kind of special token layer in Conduit, but I think that would be a lot harder to manage in the hosting case. This gives us a more direct attack on trusting requests from machines and recognizing machines as first (well, sort of second-class) actors without needing things like fake user accounts.
Test Plan:
- Added and removed SSH keys.
- Added and removed SSH keys from a bot account.
- Tried to edit an unonwned SSH key (denied).
- Ran `bin/ssh-auth`, got sensible output.

Via HackerOne. If a user adds an email address and typos it, entering `alinculne@gmailo.com`, and it happens to be a valid address which an evil user controls, the evil user can request a password reset and compromise the account.

- If an account has no verified addresses (e.g., is a new account), send to any address.

Fixes T5509. Currently, existing sessions live on even if you change your password.
Over the course of the program, we've recieved a lot of HackerOne reports that sessions do not terminate when users change their passwords. I hold that this isn't a security vulnerability: users can explicitly manage sessions, and this is more general and more powerful than tying session termination to password resets. In particular, many installs do not use a password provider at all (and no researcher has reported this in a general, application-aware way that discusses multiple authentication providers).
That said, dealing with these false positives is vaguely time consuming, and the "expected" behavior isn't bad for users, so just align behavior with researcher expectations: when passwords are changed, providers are removed, or multi-factor authentication is added to an account, terminate all other active login sessions.
Test Plan:
- Using two browsers, established multiple login sessions.
- In one browser, changed account password. Saw session terminate and logout in the second browser.
- In one browser, removed an authentication provider. Saw session terminate and logout in the second browser.
- In one browser, added MFA. Saw session terminate and logout in the second browser.

Fixes T3732. Ref T1205. Ref T3116.
External accounts (like emails used as identities, Facebook accounts, LDAP accounts, etc.) are stored in "ExternalAccount" objects.
Currently, we have a very restrictive `CAN_VIEW` policy for ExternalAccounts, to add an extra layer of protection to make sure users can't use them in unintended ways. For example, it would be bad if a user could link their Phabricator account to a Facebook account without proper authentication. All of the controllers which do sensitive things have checks anyway, but a restrictive CAN_VIEW provided an extra layer of protection. Se T3116 for some discussion.
However, this means that when grey/external users take actions (via email, or via applications like Legalpad) other users can't load the account handles and can't see anything about the actor (they just see "Restricted External Account" or similar).
Balancing these concerns is mostly about not making a huge mess while doing it. This seems like a reasonable approach:
- Add `CAN_EDIT` on these objects.
- Make that very restricted, but open up `CAN_VIEW`.
- Require `CAN_EDIT` any time we're going to do something authentication/identity related.
This is slightly easier to get wrong (forget CAN_EDIT) than other approaches, but pretty simple, and we always have extra checks in place anyway -- this is just a safety net.
I'm not quite sure how we should identify external accounts, so for now we're just rendering "Email User" or similar -- clearly not a bug, but not identifying. We can figure out what to render in the long term elsewhere.

- Viewed external accounts.
- Linked an external account.
- Refreshed an external account.
- Edited profile picture.
- Viewed sessions panel.
- Published a bunch of stuff to Asana/JIRA.

Summary:
Ref T4398. This code hadn't been touched in a while and had a few crufty bits.
**One Time Resets**: Currently, password reset (and similar links) are valid for about 48 hours, but we always use one token to generate them (it's bound to the account). This isn't horrible, but it could be better, and it produces a lot of false positives on HackerOne.
Instead, use TemporaryTokens to make each link one-time only and good for no more than 24 hours.
**Coupling of Email Verification and One-Time Login**: Currently, one-time login links ("password reset links") are tightly bound to an email address, and using a link verifies that email address.
This is convenient for "Welcome" emails, so the user doesn't need to go through two rounds of checking email in order to login, then very their email, then actually get access to Phabricator.
However, for other types of these links (like those generated by `bin/auth recover`) there's no need to do any email verification.
Instead, make the email verification part optional, and use it on welcome links but not other types of links.
**Message Customization**: These links can come out of several workflows: welcome, password reset, username change, or `bin/auth recover`. Add a hint to the URI so the text on the page can be customized a bit to help users through the workflow.
**Reset Emails Going to Main Account Email**: Previously, we would send password reset email to the user's primary account email. However, since we verify email coming from reset links this isn't correct and could allow a user to verify an email without actually controlling it.
Since the user needs a real account in the first place this does not seem useful on its own, but might be a component in some other attack. The user might also no longer have access to their primary account, in which case this wouldn't be wrong, but would not be very useful.
Mitigate this in two ways:
- First, send to the actual email address the user entered, not the primary account email address.
- Second, don't let these links verify emails: they're just login links. This primarily makes it more difficult for an attacker to add someone else's email to their account, send them a reset link, get them to login and implicitly verify the email by not reading very carefully, and then figure out something interesting to do (there's currently no followup attack here, but allowing this does seem undesirable).
**Password Reset Without Old Password**: After a user logs in via email, we send them to the password settings panel (if passwords are enabled) with a code that lets them set a new password without knowing the old one.
Previously, this code was static and based on the email address. Instead, issue a one-time code.
**Jump Into Hisec**: Normally, when a user who has multi-factor auth on their account logs in, we prompt them for factors but don't put them in high security. You usually don't want to go do high-security stuff immediately after login, and it would be confusing and annoying if normal logins gave you a "YOU ARE IN HIGH SECURITY" alert bubble.
However, if we're taking you to the password reset screen, we //do// want to put the user in high security, since that screen requires high security. If we don't do this, the user gets two factor prompts in a row.
To accomplish this, we set a cookie when we know we're sending the user into a high security workflow. This cookie makes login finalization upgrade all the way from "partial" to "high security", instead of stopping halfway at "normal". This is safe because the user has just passed a factor check; the only reason we don't normally do this is to reduce annoyance.
**Some UI Cleanup**: Some of this was using really old UI. Modernize it a bit.
Test Plan:
- **One Time Resets**
- Used a reset link.
- Tried to reuse a reset link, got denied.
- Verified each link is different.

Summary:
Ref T4398. We have several auth-related systems which require (or are improved by) the ability to hand out one-time codes which expire after a short period of time.
In particular, these are:
- SMS multi-factor: we need to be able to hand out one-time codes for this in order to prove the user has the phone.
- Password reset emails: we use a time-based rotating token right now, but we could improve this with a one-time token, so once you reset your password the link is dead.
- TOTP auth: we don't need to verify/invalidate keys, but can improve security by doing so.
This adds a generic one-time code storage table, and strengthens the TOTP enrollment process by using it. Specifically, you can no longer edit the enrollment form (the one with a QR code) to force your own key as the TOTP key: only keys Phabricator generated are accepted. This has no practical security impact, but generally helps raise the barrier potential attackers face.
Followup changes will use this for reset emails, then implement SMS multi-factor.
Test Plan:
- Enrolled in TOTP multi-factor auth.
- Submitted an error in the form, saw the same key presented.
- Edited the form with web tools to provide a different key, saw it reject and the server generate an alternate.
- Change the expiration to 5 seconds instead of 1 hour, submitted the form over and over again, saw it cycle the key after 5 seconds.
- Looked at the database and saw the tokens I expected.
- Ran the GC and saw all the 5-second expiry tokens get cleaned up.

- But also add more help/context to help users figure out what's going on here, I think it's not very obvious if you don't already know what "TOTP" is.
- Add admin tool to strip auth factors off an account ("Help, I lost my phone and can't log in!").
- Add admin tool to show users who don't have multi-factor auth? (so you can pester them)

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.

- We don't check CSRF tokens either, so after fixing the first thing, an attacker can still trick a //logged-out// victim in the same way.
It's not really clear that doing this opens up any significant attacks afterward, but both of these behaviors aren't good.

Summary:
Fixes T3793. There's a lot of history here, see D4012, T2102. Basically, the problem is that things used to work like this:
- User is logged out and accesses `/xyz/`. After they login, we'd like to send them back to `/xyz/`, so we set a `next_uri` cookie.
- User's browser has a bunch of extensions and now makes a ton of requests for stuff that doesn't exist, like `humans.txt` and `apple-touch-icon.png`. We can't distinguish between these requests and normal requests in a general way, so we write `next_uri` cookies, overwriting the user's intent (`/xyz/`).
To fix this, we made the 404 page not set `next_uri`, in D4012. So if the browser requests `humans.txt`, we 404 with no cookie, and the `/xyz/` cookie is preserved. However, this is bad because an attacker can determine if objects exist and applications are installed, by visiting, e.g., `/T123` and seeing if they get a 404 page (resource really does not exist) or a login page (resource exists). We'd rather not leak this information.
The comment in the body text describes this in more detail.
This diff sort of tries to do the right thing most of the time: we write the cookie only if we haven't written it in the last 2 minutes. Generally, this should mean that the original request to `/xyz/` writes it, all the `humans.txt` requests don't write it, and things work like users expect. This may occasionally do the wrong thing, but it should be very rare, and we stop leaking information about applications and objects.
Test Plan: Logged out, clicked around / logged in, used Charles to verify that cookies were set in the expected way.

Summary:
Ref T4339. Ref T4310. Currently, sessions look like `"afad85d675fda87a4fadd54"`, and are only issued for logged-in users. To support logged-out CSRF and (eventually) external user sessions, I made two small changes:
- First, sessions now have a "kind", which is indicated by a prefix, like `"A/ab987asdcas7dca"`. This mostly allows us to issue session queries more efficiently: we don't have to issue a query at all for anonymous sessions, and can join the correct table for user and external sessions and save a query. Generally, this gives us more debugging information and more opportunity to recover from issues in a user-friendly way, as with the "invalid session" error in this diff.
- Secondly, if you load a page and don't have a session, we give you an anonymous session. This is just a secret with no special significance.
This does not implement CSRF yet, but gives us a client secret we can use to implement it.
Test Plan:
- Logged in.
- Logged out.
- Browsed around.
- Logged in again.
- Went through link/register.

Summary:
Fixes T4143. This mitigates the "use a botnet to slowly try to login to every user account using the passwords '1234', 'password', 'asdfasdf', ..." attack, like the one that hit GitHub.
(I also donated some money to Openwall as a thanks for compiling this wordlist.)
Test Plan:
- Tried to register with a weak password; registered with a strong password.
- Tried to set VCS password to a weak password; set VCS password to a strong password.
- Tried to change password to a weak password; changed password to a strong password.

Summary:
Ref T4310. Fixes T3720. This change:
- Removes concurrent session limits. Instead, unused sessions are GC'd after a while.
- Collapses all existing "web-1", "web-2", etc., sessions into "web" sessions.
- Dramatically simplifies the code for establishing a session (like omg).
Test Plan: Ran migration, checked Sessions panel and database for sanity. Used existing session. Logged out, logged in. Ran Conduit commands.
