# Update auth rules to check notifications key in m.room.power_levels
|
||||||
|
|
||||||
|
## Introduction
|
||||||
|
|
||||||
|
The key `notifications` was added to the `m.room.power_levels` event after the
|
||||||
|
finalisation of the auth rules specified in room version 1. This leads to the
|
||||||
|
fact, that this dictionary is not subject to the same validation as other
|
||||||
|
dictionaries in the event, such as `users` or `events`. This especially means
|
||||||
|
that Alice is able to alter any entry within the dictionary including ones,
|
||||||
|
that are above her own power level, which is inconsistent with the behaviour
|
||||||
|
for the other two dictionaries.
|
||||||
|
|
||||||
|
[m.room.power_levels](https://matrix.org/docs/spec/client_server/r0.5.0#m-room-power-levels)
|
||||||
|
[room version 1](https://matrix.org/docs/spec/rooms/v1)
|
||||||
|
|
||||||
|
## Proposal
|
||||||
|
|
||||||
|
The auth rules regarding `m.room.power_levels` have been established in room
|
||||||
|
version 1. The general idea here was that creators of a new `m.room.power_levels`
|
||||||
|
event are only able to make changes to something that is equal to or lower than
|
||||||
|
their own power level.
|
||||||
|
So, assuming a room with Alice (50), Bob (100), `m.room.power_levels` at 50,
|
||||||
|
`m.room.name` at 75 and `m.room.topic` at 25 would mean the following:
|
||||||
|
|
||||||
|
* Alice CAN alter `m.room.topic` to any power level up to her own, in this case 50
|
||||||
|
* Alice is NOT able to alter `m.room.name` since the current value is higher than
|
||||||
|
her own (75 > 50)
|
||||||
|
* Alice is NOT able to alter the power level of Bob, since his current value is
|
||||||
|
higher than her own (100 > 50)
|
||||||
|
* Alice is free to set the level for anything that has not been defined such as
|
||||||
|
`org.alice.message` up to a maximum of 50
|
||||||
|
|
||||||
|
Later on the key `notifications` was added to the `m.room.power_levels` event.
|
||||||
|
It contains a mapping of notification keys to a power level, that is required
|
||||||
|
for a user to trigger the specific notification. The most famous notification
|
||||||
|
type is the `@room` notification.
|
||||||
|
|
||||||
|
Going back to the original example because this key was added later on, the auth
|
||||||
|
rules make no mention of it, which enables the following behaviour. *It is assumed
|
||||||
|
that `@room` is at 75*
|
||||||
|
|
||||||
|
* Alice can add any key to the dictionary and set the value to any value she wants,
|
||||||
|
including ones higher than her own.
|
||||||
|
* Alice can alter the value for `@room` to any value she wants, including ones that
|
||||||
|
are higher than her own, even though her own value is lower.
|
||||||
|
|
||||||
|
The proposed solution is to alter the auth rules and add the `notifications` dictionary
|
||||||
|
to the same rules that handle `events` and `users`.
|
||||||
|
|
||||||
|
So the rule [10.d](https://matrix.org/docs/spec/rooms/v1.html) of the auth rules in
|
||||||
|
room version 1 would be updated in a new room version to:
|
||||||
|
|
||||||
|
|
||||||
|
> For each entry being added, changed or removed in events, users __and notifications__
|
||||||
|
>keys:
|
||||||
|
|
||||||
|
|
||||||
|
## Tradeoffs
|
||||||
|
|
||||||
|
The proposed solution would be a breaking change with current room versions and
|
||||||
|
the alternative would be to leave the `notifications` key without any checks.
|
||||||
|
|
||||||
|
## Security considerations
|
||||||
|
|
||||||
|
This is likely to improve security because it prevents malicious users that were
|
||||||
|
only given the right to emit `m.room.power_levels` so that they could alter a very
|
||||||
|
specific key, such as `invite`, from altering the rules established for triggering
|
||||||
|
notifications.
|
||||||
|
|
||||||
|
## Conclusion
|
||||||
|
|
||||||
|
The current spec conform behaviour regarding `notifications` is inconsistent with
|
||||||
|
behaviour shown by the other dictionaries and room administrators are very likely
|
||||||
|
expecting the `notifications` to work the same as them. The required change is minimal
|
||||||
|
is and also in line with the general spirit of the auth rules regarding the
|
||||||
|
`m.room.power_levels` event. A new room version is, however, required. This can be
|
||||||
|
done with other pending changes.

# MSC2240: Room Version 6
|
||||||
|
|
||||||
|
A new room version, `6`, is proposed using [room version 5](https://matrix.org/docs/spec/rooms/v5.html) as a base
|
||||||
|
and incorporating the following MSCs:
|
||||||
|
|
||||||
|
* [MSC2209](https://github.com/matrix-org/matrix-doc/pull/2209) - Including notifications in power level auth rules.
|
||||||
|
* [MSC2432](https://github.com/matrix-org/matrix-doc/pull/2432) - Alias event authorisation and redaction.
|
||||||
|
* [MSC2540](https://github.com/matrix-org/matrix-doc/pull/2540) - Integers in canonical JSON compliance.
|
||||||
|
|
||||||
|
Though other MSCs are capable of being included in this version, they do not have sufficient implementation to be
|
||||||
|
considered stable enough for v6 rooms. A future room version may still include them.
|
||||||
|
|
||||||
|
Room version 6 upon being added to the specification shall be considered stable. No other room versions are affected
|
||||||
|
by this MSC.

# Proposal for mandating case folding when processing e-mail addresses
|
||||||
|
|
||||||
|
[RFC822](https://tools.ietf.org/html/rfc822#section-3.4.7) mandates that
|
||||||
|
localparts in e-mail addresses must be processed with the original case
|
||||||
|
preserved. [The Matrix spec](https://matrix.org/docs/spec/appendices#pid-types)
|
||||||
|
doesn't mandate anything about processing e-mail addresses, other than the fact
|
||||||
|
that the domain part must be converted to lowercase, as domain names are case
|
||||||
|
insensitive.
|
||||||
|
|
||||||
|
On the other hand, most major e-mail providers nowadays process the localparts
|
||||||
|
of e-mail addresses as case insensitive. Therefore, most users expect localparts
|
||||||
|
to be treated case insensitively, and get confused when it's not. Some users,
|
||||||
|
for example, get confused over the fact that registering a 3PID association for
|
||||||
|
`john.doe@example.com` doesn't mean that the association is valid for
|
||||||
|
`John.Doe@example.com`, and don't expect to have to remember the exact
|
||||||
|
case they used to initially register the association (and sometimes get locked
|
||||||
|
out of their account because of that). So far we've seen that confusion occur
|
||||||
|
and lead to troubles of various degrees over several deployments of Synapse and
|
||||||
|
Sydent.
|
||||||
|
|
||||||
|
## Proposal
|
||||||
|
|
||||||
|
This proposal suggests changing the specification of the e-mail 3PID type in
|
||||||
|
[the Matrix spec appendices](https://matrix.org/docs/spec/appendices#pid-types)
|
||||||
|
to mandate that, before any processing, e-mail addresses must go through a full
|
||||||
|
case folding based on [the unicode mapping
|
||||||
|
file](https://www.unicode.org/Public/8.0.0/ucd/CaseFolding.txt), on top of
|
||||||
|
having their domain lowercased.
|
||||||
|
|
||||||
|
This means that `Strauß@Example.com` must be considered as being the same e-mail
|
||||||
|
address as `strauss@example.com`.
|
||||||
|
|
||||||
|
## Other considered solutions
|
||||||
|
|
||||||
|
A first look at this issue concluded that there was no need to add such a
|
||||||
|
mention to the spec, and that it can be considered an implementation detail.
|
||||||
|
However, [MSC2134](https://github.com/matrix-org/matrix-doc/pull/2134) changes
|
||||||
|
this: because hashing functions are case sensitive, we need both clients and
|
||||||
|
identity servers to follow the same policy regarding case sensitivity.
|
||||||
|
|
||||||
|
An initial version of this proposal proposed to mandate lowercasing e-mail
|
||||||
|
addresses instead of case folding them, however it was pointed out that this
|
||||||
|
solution might not be the best and most future-proof one.
|
||||||
|
|
||||||
|
Unicode normalisation was also looked at but judged unnecessary.
|
||||||
|
|
||||||
|
## Tradeoffs
|
||||||
|
|
||||||
|
Implementing this MSC in identity servers and homeservers might require the
|
||||||
|
databases of existing instances to be updated in a large part to case fold the
|
||||||
|
email addresses of existing associations, in order to avoid conflicts. However,
|
||||||
|
most of this update can usually be done by a background job running at startup,
|
||||||
|
so the UX improvement outweighs this trouble.
|
||||||
|
|
||||||
|
## Potential issues
|
||||||
|
|
||||||
|
### Conflicts with existing associations
|
||||||
|
|
||||||
|
Some users might already have two different accounts associated with the same
|
||||||
|
e-mail address but with different cases. This appears to happen in a small
|
||||||
|
number of cases, however, and can be dealt with by the identity server's or the
|
||||||
|
homeserver's maintainer.
|
||||||
|
|
||||||
|
For example, with Sydent, the process of dealing with such cases could look
|
||||||
|
like:
|
||||||
|
|
||||||
|
1. list all MXIDs associated with a variant of the email address, and the
|
||||||
|
timestamp of that association
|
||||||
|
2. delete all associations except for the most recent one [0]
|
||||||
|
3. inform the user of the deletion by sending them an email notice to the email
|
||||||
|
address
|
||||||
|
|
||||||
|
### Storing and querying
|
||||||
|
|
||||||
|
Most database engines don't support case folding, therefore querying all
|
||||||
|
e-mail addresses matching a case folded e-mail address might not be trivial,
|
||||||
|
e.g. an identity server querying all associations for `strauss@example.com` when
|
||||||
|
processing a `/lookup` request would be expected to also get associations for
|
||||||
|
`Strauß@Example.com`.
|
||||||
|
|
||||||
|
To address this issue, implementation maintainers are strongly encouraged to
|
||||||
|
make e-mail addresses go through a full case folding before storing them.
|
||||||
|
|
||||||
|
### Implementing case folding
|
||||||
|
|
||||||
|
The need for case folding in services on the Internet doesn't seem to be very
|
||||||
|
large currently (probably due to its young age), therefore there seem to be only
|
||||||
|
a few third-party implementation librairies out there. However, both
|
||||||
|
[Go](https://godoc.org/golang.org/x/text/cases#Fold), [Python
|
||||||
|
2](https://docs.python.org/2/library/stringprep.html#stringprep.map_table_b3)
|
||||||
|
and [Python 3](https://docs.python.org/3/library/stdtypes.html#str.casefold)
|
||||||
|
support it natively, and [a third-party JavaScript
|
||||||
|
implementation](https://github.com/ar-nelson/foldcase) exists which, although
|
||||||
|
young, seems to be working.
|
||||||
|
|
||||||
|
## Footnotes
|
||||||
|
|
||||||
|
[0]: This is specific to Sydent because of a bug it has where v1 lookups are
|
||||||
|
already processed case insensitively, which means it will return the most recent
|
||||||
|
association for any case of the given email address, therefore keeping only this
|
||||||
|
association won't change the result of v1 lookups.

# User-Interactive Authentication for SSO-backed homeserver
|
||||||
|
|
||||||
|
Certain endpoints, such as `DELETE /_matrix/client/r0/devices/{deviceId}` and
|
||||||
|
`POST /_matrix/client/r0/account/3pid/add`, require the user to reconfirm their
|
||||||
|
identity, as a guard against a leaked access token being used to take over an
|
||||||
|
entire account.
|
||||||
|
|
||||||
|
On a normal homeserver, this is done by prompting the user to enter their
|
||||||
|
password. However, on a homeserver where users authenticate via a single-sign-on
|
||||||
|
system, the user doesn't have a password registered with the homeserver. Instead
|
||||||
|
we need to delegate that check to the SSO system.
|
||||||
|
|
||||||
|
At the protocol level, this means adding support for SSO to the
|
||||||
|
[user-interactive authentication API](https://matrix.org/docs/spec/client_server/r0.6.0#user-interactive-authentication-api).
|
||||||
|
|
||||||
|
In theory, once SSO is added as a possible flow for authentication, any clients
|
||||||
|
that already implement the [fallback process for unknown authentication types](https://matrix.org/docs/spec/client_server/r0.6.0#fallback)
|
||||||
|
will work fine without modification. It is unknown whether this is widely
|
||||||
|
supported among clients.
|
||||||
|
|
||||||
|
## Proposal
|
||||||
|
|
||||||
|
An [additional authentication type](https://matrix.org/docs/spec/client_server/r0.6.0#authentication-types)
|
||||||
|
of `m.login.sso` is added to the user-interactive authentication specification.
|
||||||
|
|
||||||
|
There are no additional parameters as part of this authentication type. As per
|
||||||
|
the user-interactive authentication specification, the only parameter included in
|
||||||
|
the `auth` dictionary should be the session ID from the homeserver, e.g.:
|
||||||
|
|
||||||
|
```json
|
||||||
|
{
|
||||||
|
"auth": {
|
||||||
|
"session": "<session ID>"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
### Detailed fallback authentication flow:
|
||||||
|
|
||||||
|
The following is a re-iteration of the [fallback authentication flow](https://matrix.org/docs/spec/client_server/r0.6.0#fallback),
|
||||||
|
but with details filled in for the proposed new authentication type.
|
||||||
|
|
||||||
|
When choosing this authentication flow, the following should occur:
|
||||||
|
|
||||||
|
1. If the client wants to complete authentication using SSO, it opens a browser
|
||||||
|
window for `/_matrix/client/r0/auth/m.login.sso/fallback/web?session=<...>`
|
||||||
|
with session set to the UI-Auth session id (from the "auth" dict).
|
||||||
|
|
||||||
|
The homeserver returns a page which asks for the user's confirmation before
|
||||||
|
proceeding. See the security considerations section below for why this is
|
||||||
|
necessary. For example, the page could say words to the effect of:
|
||||||
|
|
||||||
|
> A client is trying to remove a device/add an email address/take over your
|
||||||
|
> account. To confirm this action, **re-authenticate with single sign-on**.
|
||||||
|
> If you did not expect this, your account may be compromised!
|
||||||
|
2. The link, once the user clicks on it, goes to the SSO provider's page.
|
||||||
|
3. The SSO provider validates the user, and redirects the browser back to the
|
||||||
|
homeserver.
|
||||||
|
4. The homeserver validates the response from the SSO provider, updates the
|
||||||
|
user-interactive auth session to show that the SSO has completed, and
|
||||||
|
[serves the fallback auth completion page as specced](https://matrix.org/docs/spec/client_server/r0.6.0#fallback).
|
||||||
|
5. The client resubmits its original request, with its original session id,
|
||||||
|
which now should complete.
|
||||||
|
|
||||||
|
Note that the post-SSO URL on the homeserver is left up to the homeserver
|
||||||
|
implementation rather than forming part of the specification, choices might be
|
||||||
|
limited by the chosen SSO implementation, for example:
|
||||||
|
|
||||||
|
* SAML2 servers typically only support one URL per service provider, so in
|
||||||
|
practice it will need to be the same as that already used for the login flow
|
||||||
|
(for synapse, it's `/_matrix/saml2/authn_response`) - and the server needs to
|
||||||
|
be able to figure out if it's doing SSO for a login attempt or an SSO
|
||||||
|
attempt.
|
||||||
|
* CAS doesn't have the same restriction.
|
||||||
|
|
||||||
|
### Example flow:
|
||||||
|
|
||||||
|
A more complete example is provided below in which a user attempts to delete
|
||||||
|
a device and is pushed into the user interactive authentication process with
|
||||||
|
SSO being the only possible flow.
|
||||||
|
|
||||||
|
0. Client submits the request, which the server says requires SSO:
|
||||||
|
|
||||||
|
```
|
||||||
|
POST /_matrix/client/r0/delete_devices HTTP/1.1
|
||||||
|
Content-Type: application/json
|
||||||
|
Authorization: Bearer xyzzy
|
||||||
|
|
||||||
|
{
|
||||||
|
"devices": ["FSVVTZRRAA"]
|
||||||
|
}
|
||||||
|
|
||||||
|
HTTP/1.1 401 Unauthorized
|
||||||
|
Content-Type: application/json
|
||||||
|
|
||||||
|
{
|
||||||
|
"flows": [
|
||||||
|
{
|
||||||
|
"stages": [
|
||||||
|
"m.login.sso"
|
||||||
|
]
|
||||||
|
}
|
||||||
|
],
|
||||||
|
"params": {},
|
||||||
|
"session": "dTKfsLHSAJeAhqfxUsvrIVJd"
|
||||||
|
}
|
||||||
|
```
|
||||||
|
|
||||||
|
1. Client opens a browser window for the fallback endpoint:
|
||||||
|
|
||||||
|
```
|
||||||
|
GET /_matrix/client/r0/auth/m.login.sso/fallback/web
|
||||||
|
?session=dTKfsLHSAJeAhqfxUsvrIVJd HTTP/1.1
|
||||||
|
|
||||||
|
HTTP/1.1 200 OK
|
||||||
|
|
||||||
|
<body>
|
||||||
|
A client is trying to remove a device from your account. To confirm this
|
||||||
|
action, <a href="https://sso_provider/validate?SAMLRequest=...">re-authenticate with single sign-on</a>.
|
||||||
|
If you did not expect this, your account may be compromised!
|
||||||
|
</body>
|
||||||
|
```
|
||||||
|
|
||||||
|
2. The user clicks the confirmation link which goes to the SSO provider's site:
|
||||||
|
|
||||||
|
```
|
||||||
|
GET https://sso_provider/validate?SAMLRequest=<etc> HTTP/1.1
|
||||||
|
|
||||||
|
<SAML/CAS or other SSO data>
|
||||||
|
```
|
||||||
|
|
||||||
|
3. The SSO provider validates the user and ends up redirecting the browser back
|
||||||
|
to the homeserver. The example below shows a 302 for simplicity, this might
|
||||||
|
vary based on SSO implementation.
|
||||||
|
|
||||||
|
```
|
||||||
|
HTTP/1.1 302 Moved
|
||||||
|
Location: https://homeserver/_matrix/saml2/authn_response?
|
||||||
|
SAMLResponse=<etc>
|
||||||
|
```
|
||||||
|
|
||||||
|
4. The browser sends the SSO response to the homeserver, which validates it and
|
||||||
|
shows the fallback auth completion page:
|
||||||
|
|
||||||
|
```
|
||||||
|
GET /_matrix/saml2/authn_response?SAMLResponse=<etc>
|
||||||
|
|
||||||
|
|
||||||
|
HTTP/1.1 200 OK
|
||||||
|
|
||||||
|
<script>
|
||||||
|
if (window.onAuthDone) {
|
||||||
|
window.onAuthDone();
|
||||||
|
} else if (window.opener && window.opener.postMessage) {
|
||||||
|
window.opener.postMessage("authDone", "*");
|
||||||
|
}
|
||||||
|
</script>
|
||||||
|
|
||||||
|
<p>Thank you.</p>
|
||||||
|
<p>You may now close this window and return to the application.</p>
|
||||||
|
```
|
||||||
|
|
||||||
|
5. The client closes the browser popup if it is still open, and resubmits its
|
||||||
|
original request, which now succeeds:
|
||||||
|
|
||||||
|
```
|
||||||
|
POST /_matrix/client/r0/delete_devices HTTP/1.1
|
||||||
|
Content-Type: application/json
|
||||||
|
Authorization: Bearer xyzzy
|
||||||
|
|
||||||
|
{
|
||||||
|
"auth": {
|
||||||
|
"session": "dTKfsLHSAJeAhqfxUsvrIVJd"
|
||||||
|
}
|
||||||
|
}
|
||||||
|
|
||||||
|
HTTP/1.1 200 OK
|
||||||
|
Content-Type: application/json
|
||||||
|
|
||||||
|
{}
|
||||||
|
```
|
||||||
|
|
||||||
|
## Alternatives
|
||||||
|
|
||||||
|
An alternative client flow where the fallback auth ends up redirecting to a
|
||||||
|
given URI, instead of doing JavaScript `postMessage` foo could be considered.
|
||||||
|
This is probably an orthogonal change to the fallback auth though.
|
||||||
|
|
||||||
|
## Security considerations
|
||||||
|
|
||||||
|
### Why we need user to confirm before the SSO flow
|
||||||
|
|
||||||
|
Recall that the thing we are trying to guard against here is a single leaked
|
||||||
|
access-token being used to take over an entire account. So let's assume the
|
||||||
|
attacker has got hold of an access token for your account. What happens if the
|
||||||
|
confirmation step is skipped?
|
||||||
|
|
||||||
|
The attacker, who has your access token, starts a UI Authentication session to
|
||||||
|
add their email address to your account.
|
||||||
|
|
||||||
|
They then sends you a link "hey, check out this cool video!"; the link leads (via
|
||||||
|
an innocent-looking URL shortener or some other phishing technique) to
|
||||||
|
`/_matrix/client/r0/auth/m.login.sso/fallback/web?session=<...>`, with the ID of
|
||||||
|
the session that he just created.
|
||||||
|
|
||||||
|
Since there is no confirmation step, the server redirects directly to the SSO
|
||||||
|
provider.
|
||||||
|
|
||||||
|
It's common for SSO providers to redirect straight back to the app if you've
|
||||||
|
recently authenticated with them; even in the best case, the SSO provider shows
|
||||||
|
an innocent message along the lines of "Confirm that you want to sign in to
|
||||||
|
\<your Matrix homeserver>".
|
||||||
|
|
||||||
|
After redirecting back to the homeserver, the SSO is completed and the
|
||||||
|
attacker's session is validated. They are now able to make their malicious
|
||||||
|
change to your account.
|
||||||
|
|
||||||
|
This problem can be mitigated by clearly telling the user what is about to happen.
|
||||||
|
|
||||||
|
### Reusing User Interactive Authentication sessions
|
||||||
|
|
||||||
|
The security of this relies on User Interactive Authentication sessions only
|
||||||
|
being used for the same request as they were initiated for. This security is not
|
||||||
|
only a concern for the proposed SSO authentication type. It is not believed
|
||||||
|
that this is currently enforced in implementations.
|
||||||
|
|
||||||
|
## Unstable prefix
|
||||||
|
|
||||||
|
A vendor prefix of `org.matrix.login.sso` is proposed (instead of `m.login.sso`)
|
||||||
|
until this is part of the specification.

# Invalidating devices during password modification
|
||||||
|
|
||||||
|
There are multiple use cases for why a user might want to modify their password:
|
||||||
|
|
||||||
|
* Adopting a password manager (to use a unique password or more secure password).
|
||||||
|
* Password rotation.
|
||||||
|
* Re-secure a compromised account.
|
||||||
|
* ... probably tons of others ...
|
||||||
|
|
||||||
|
These can be summarized into two groups:
|
||||||
|
|
||||||
|
1. "My account has been compromised and I need to re-secure it."
|
||||||
|
2. "I just want to change my password."
|
||||||
|
|
||||||
|
The [current Matrix specification](https://matrix.org/docs/spec/client_server/r0.6.0#post-matrix-client-r0-account-password)
|
||||||
|
does not provide a way to differentiate between these use cases. It currently
|
||||||
|
specifies behavior that fits well into the first use-case above: that the
|
||||||
|
sessions except the current session should be revoked.
|
||||||
|
|
||||||
|
It is reasonable for a client to want to specify this behavior to offer two
|
||||||
|
different workflows:
|
||||||
|
|
||||||
|
1. Modify a password and log all other devices out (for use when an account has
|
||||||
|
been compromised).
|
||||||
|
2. Modify a password and do not touch any session data (for use in a
|
||||||
|
non-malicious situations).
|
||||||
|
|
||||||
|
Alternately a client may default to whichever workflow is best for their users.
|
||||||
|
|
||||||
|
## Proposal
|
||||||
|
|
||||||
|
An optional field is added to the JSON body of the [password reset endpoint](https://matrix.org/docs/spec/client_server/r0.6.0#post-matrix-client-r0-account-password)
|
||||||
|
called `logout_devices`. This is a boolean flag (defaulting to `true`) that
|
||||||
|
signals to whether other devices and sessions should be invalidated after
|
||||||
|
modifying the password.
|
||||||
|
|
||||||
|
## Potential issues
|
||||||
|
|
||||||
|
The specification states:
|
||||||
|
|
||||||
|
> The homeserver SHOULD NOT revoke the access token provided in the request,
|
||||||
|
> however all other access tokens for the user should be revoked if the request
|
||||||
|
> succeeds.
|
||||||
|
|
||||||
|
Defaulting `logout_devices` to `true` should be backwards compatible.
|
||||||
|
|
||||||
|
## Alternatives
|
||||||
|
|
||||||
|
A new endpoint could be provided in a future version of the specification that
|
||||||
|
supports an additional field (as described above).
|
||||||
|
|
||||||
|
## Security considerations
|
||||||
|
|
||||||
|
By defaulting to invalidating devices and sessions the security considerations
|
||||||
|
of this endpoint should remain intact. A client will need to be modified to
|
||||||
|
choose to keep other devices active.

# Symmetric SSSS
|
||||||
|
|
||||||
|
[MSC1946 (Secure Secret Storage and
|
||||||
|
Sharing)](https://github.com/matrix-org/matrix-doc/pull/1946) proposed a way of
|
||||||
|
storing encrypted secrets on the server. In the proposal, secrets were
|
||||||
|
encrypted using a Curve25519 key, which was chosen to allow easier migration
|
||||||
|
from key backups that we created before the backup key was stored using it.
|
||||||
|
|
||||||
|
However this does not provide any guarantees that data stored using the
|
||||||
|
proposal came from a trusted source. To remedy this, we propose to change the
|
||||||
|
encryption to use AES with a MAC to ensure that only someone who knows the key
|
||||||
|
is able to store data.
|
||||||
|
|
||||||
|
## Proposal
|
||||||
|
|
||||||
|
* The `m.secret_storage.v1.curve25519-aes-sha2` method proposed in MSC1946 is
|
||||||
|
removed.
|
||||||
|
|
||||||
|
* A new method, `m.secret_storage.v1.aes-hmac-sha2`, is added. With this
|
||||||
|
method, the Secret Storage key may be any size (though 256 bits is
|
||||||
|
recommended), and data is encrypted as follows:
|
||||||
|
|
||||||
|
1. Given the secret storage key, generate 64 bytes by performing an HKDF with
|
||||||
|
SHA-256 as the hash, a salt of 32 bytes of 0, and with the secret name as
|
||||||
|
the info. The first 32 bytes are used as the AES key, and the next 32 bytes
|
||||||
|
are used as the MAC key
|
||||||
|
2. Generate 16 random bytes, set bit 63 to 0 (in order to work around
|
||||||
|
differences in AES-CTR implementations), and use this as the AES
|
||||||
|
initialization vector. This becomes the `iv` property, encoded using base64.
|
||||||
|
3. Encrypt the data using AES-CTR-256 using the AES key generated above. This
|
||||||
|
encrypted data, encoded using base64, becomes the `ciphertext` property.
|
||||||
|
4. Pass the raw encrypted data (prior to base64 encoding) through HMAC-SHA-256
|
||||||
|
using the MAC key generated above. The resulting MAC is base64-encoded and
|
||||||
|
becomes the `mac` property.
|
||||||
|
|
||||||
|
(We use AES-CTR to match file encryption and key exports.)
|
||||||
|
|
||||||
|
If the key Secret Storage key is generated from a passphrase, information
|
||||||
|
about how to generate the key is stored in the `passphrase` property of the
|
||||||
|
key's account-data in a similar manner to what was done with the original
|
||||||
|
`m.secret_storage.v1.curve25519-aes-sha2` method, except that there is an
|
||||||
|
optional `bits` parameter that defaults to 256, and indicates the number of
|
||||||
|
bits that should be generated from PBKDF2 (in other words, the size of the
|
||||||
|
key).
|
||||||
|
|
||||||
|
* For the purposes of allowing clients to check whether a user has correctly
|
||||||
|
entered the key, clients should:
|
||||||
|
|
||||||
|
1. encrypt and MAC a message consisting of 32 bytes of 0 as described above,
|
||||||
|
using the empty string as the info parameter to the HKDF in step 1.
|
||||||
|
2. store the `iv` and `mac` in the `m.secret_storage.key.[key ID]`
|
||||||
|
account-data.
|
||||||
|
|
||||||
|
* The `passthrough` property specified in the "Enconding the recovery key for
|
||||||
|
server-side storage via MSC1946" section of MSC1219 is removed. The primary
|
||||||
|
purpose of that property was to allow easy migration of pre-MSC1946 backups,
|
||||||
|
so that users could reuse the backup recovery key as the Secret Storage key
|
||||||
|
without needing to re-enter the recovery key. However, since we are now
|
||||||
|
using a symmetric encryption algorithm, the client needs to know the key that
|
||||||
|
is used to encrypt, so the purpose of the field cannot be fulfilled.
|
||||||
|
|
||||||
|
* Signing the Secret Storage key with the user's master cross-signing key is no
|
||||||
|
longer required. The key is trusted on the basis of the user entering the
|
||||||
|
key/passphrase.
|
||||||
|
|
||||||
|
|
||||||
|
## Potential issues
|
||||||
|
|
||||||
|
Users who have data stored using the old encryption algorithm will need their
|
||||||
|
data migrated. Clients that support the old algorithm but not the new
|
||||||
|
algorithm will not be able to use the migrated secrets until they are updated
|
||||||
|
with the new algorithms. This should not be a major problem because the only
|
||||||
|
clients that are known to have implemented the old algorithm are Riot
|
||||||
|
Web/Android/iOS, and they have been upgraded to implement the new algorithm.
|
||||||
|
|
||||||
|
|
||||||
|
## Alternatives
|
||||||
|
|
||||||
|
Rather than switching to a symmetric encryption algorithm, we could stay with
|
||||||
|
an asymmetric encryption algorithm, and add on a method to authenticate the
|
||||||
|
data. However, it is much safer to use well-known cryptographic methods rather
|
||||||
|
than trying to invent something new. Since the main reason for using an
|
||||||
|
asymmetric scheme was to ease migration from older key backups without
|
||||||
|
requiring the user to re-enter the key, but this is no longer possible due to
|
||||||
|
the need to authenticate the data using the Secret Storage key, there is no
|
||||||
|
reason to stay with an asymmetric algorithm. It is also better to use
|
||||||
|
cryptographic methods already used in Matrix where possible, rather than
|
||||||
|
introducing something new.

# MSC2526: Add ability to delete key backups

# MSC2540: Stricter event validation: JSON compliance
|
||||||
|
|
||||||
|
## Background
|
||||||
|
|
||||||
|
There has been [prior discussions](https://github.com/matrix-org/matrix-doc/issues/1646)
|
||||||
|
about validating events more strictly. This MSC proposes fixing a small piece of
|
||||||
|
this: JSON compliance.
|
||||||
|
|
||||||
|
The [Canonical JSON](https://matrix.org/docs/spec/appendices#canonical-json)
|
||||||
|
specification requires that numbers that are serialized in JSON are integers in
|
||||||
|
the inclusive range of `[-(2^53) + 1, (2^53) - 1]`, which matches the requirements of
|
||||||
|
[section 6 of RFC 7159](https://tools.ietf.org/html/rfc7159). Note that it is
|
||||||
|
not explicit, but all floats are invalid.
|
||||||
|
|
||||||
|
It is worth mentioning that there are common extensions to JSON which produce
|
||||||
|
invalid JSON according to the Matrix specification; some programming langauges
|
||||||
|
even support these by default. One common additional feature is handling
|
||||||
|
"special" float values: `Infinity`, `-Infinity`, and `NaN`.
|
||||||
|
|
||||||
|
|
||||||
|
## Proposal
|
||||||
|
|
||||||
|
In a future room version, homeserver implementations are to strictly enforce
|
||||||
|
the JSON compliance of the Canonical JSON specification for events.
|
||||||
|
Non-compliant events should be treated like any other malformed event,
|
||||||
|
for example by rejecting the request with an HTTP 400 error with `M_BAD_JSON`,
|
||||||
|
or by discarding the event.
|
||||||
|
|
||||||
|
The rationale for doing this in a future room version is to avoid a split brain
|
||||||
|
room -- where some federated servers believe an event is valid and others reject
|
||||||
|
it as invalid. Rooms will be able to opt into this behavior as part of a room
|
||||||
|
version upgrade.
|
||||||
|
|
||||||
|
Homeserver implementations are not to strictly enforce this JSON compliance in
|
||||||
|
[room versions 1, 2, 3, 4, and 5](https://matrix.org/docs/spec/#complete-list-of-room-versions).
|
||||||
|
The rationale is essentially the same as why a future room version is necessary:
|
||||||
|
this ensures that all federated servers treat the same events as valid.
|
||||||
|
|
||||||
|
|
||||||
|
## Potential issues
|
||||||
|
|
||||||
|
Homeserver implementations might include JSON parsers which are stricter than
|
||||||
|
others. It may not be worthwhile or reasonable to loosen those restrictions for
|
||||||
|
stable room versions.
|
||||||
|
|
||||||
|
|
||||||
|
## Alternatives
|
||||||
|
|
||||||
|
It could be argued that this MSC is unnecessary since it does not add any new
|
||||||
|
requirements for handling of JSON data. Unfortunately starting to enforce these
|
||||||
|
requirements in current rooms could cause federation to break as homeservers
|
||||||
|
will disagree on whether events are valid.

Room Version 6
|
||||||
|
==============
|
||||||
|
|
||||||
|
This room version builds on `version 5 <v5.html>`_ while changing various
|
||||||
|
authorization rules performed on events.
|
||||||
|
|
||||||
|
.. contents:: Table of Contents

||||||
|
Client considerations
|
||||||
|
---------------------
|
||||||
|
|
||||||
|
The redaction algorithm has changed from `room version 1 <v1.html>`_ to remove
|
||||||
|
all rules against events of type ``m.room.aliases``. Room versions 2, 3, 4, and
|
||||||
|
5 all use v1's redaction algorithm. The algorithm is otherwise unchanged.
|
||||||
|
|
||||||
|
|
||||||
|
Server implementation components
|
||||||
|
--------------------------------
|
||||||
|
|
||||||
|
.. WARNING::
|
||||||
|
The information contained in this section is strictly for server implementors.
|
||||||
|
Applications which use the Client-Server API are generally unaffected by the
|
||||||
|
intricacies contained here. The section above regarding client considerations
|
||||||
|
is the resource that Client-Server API use cases should reference.
|
||||||
|
|
||||||
|
|
||||||
|
Room version 6 makes the following alterations to algorithms described in `room version 5 <v5.html>`_.
|
||||||
|
|
||||||
|
Redactions
|
||||||
|
~~~~~~~~~~
|
||||||
|
|
||||||
|
As mentioned in the client considerations portion of this specification, all
|
||||||
|
special meaning has been removed for events of type ``m.room.aliases``. The
|
||||||
|
algorithm is otherwise unchanged.
|
||||||
|
|
||||||
|
Authorization rules for events
|
||||||
|
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
|
||||||
|
|
||||||
|
Like redactions, all rules relating specifically to events of type ``m.room.aliases``
|
||||||
|
are removed. They must still pass authorization checks relating to state events.
|
||||||
|
|
||||||
|
Additionally, the authorization rules for events of type ``m.room.power_levels``
|
||||||
|
now include the content key ``notifications``. This new rule takes the place of the
|
||||||
|
rule which checks the ``events`` and ``users`` keys.
|
||||||
|
|
||||||
|
For completeness, the changes to the auth rules can be represented as follows:
|
||||||
|
|
||||||
|
.. code:: diff
|
||||||
|
|
||||||
|
...
|
||||||
|
|
||||||
|
-If type is `m.room.aliases`:
|
||||||
|
-
|
||||||
|
- a. If event has no `state_key`, reject.
|
||||||
|
- b. If sender's domain doesn't matches `state_key`, reject.
|
||||||
|
- c. Otherwise, allow.
|
||||||
|
|
||||||
|
...
|
||||||
|
|
||||||
|
If type is `m.room.power_levels`:
|
||||||
|
|
||||||
|
...
|
||||||
|
|
||||||
|
- * For each entry being added, changed or removed in both the `events` and `users` keys:
|
||||||
|
+ * For each entry being added, changed or removed in the `events`, `users`, and `notifications` keys:
|
||||||
|
|
||||||
|
i. If the current value is higher than the `sender`'s current power level, reject.
|
||||||
|
|
||||||
|
ii. If the new value is higher than the `sender`'s current power level, reject.
|
||||||
|
|
||||||
|
...
|
||||||
|
|
||||||
|
|
||||||
|
The remaining rules are the same as in `room version 3 <v3.html#authorization-rules-for-events>`_
|
||||||
|
(the last inherited room version to specify the authorization rules).
|
||||||
|
|
||||||
|
Canonical JSON
|
||||||
|
~~~~~~~~~~~~~~
|
||||||
|
|
||||||
|
Servers MUST strictly enforce the JSON format specified in the
|
||||||
|
`appendices <../appendices.html#canonical-json>`_. This translates to a 400 ``M_BAD_JSON`` error
|
||||||
|
on most endpoints, or discarding of events over federation. For example, the Federation API's
|
||||||
|
``/send`` endpoint would discard the event whereas the Client Server API's ``/send/{eventType}``
|
||||||
|
endpoint would return a ``M_BAD_JSON`` error.
