Disable creating alert client instances when ESO plugin is using an ephemeral encryption key #56676

mikecote · 2020-02-03T20:46:36Z

Resolves the alerting portion of #56420.

In this PR, the alerts client will throw an error whenever trying to create an instance of the client (getAlertsClient via getAlertsClientWithRequest) and the encrypted saved objects plugin is using an ephemeral encryption key.

Error message:

Unable to create alerts client due to the Encrypted Saved Objects plugin using an ephemeral encryption key. Please set xpack.encryptedSavedObjects.encryptionKey in kibana.yml

I realize it's not much of a concern in 7.6, but wouldn't we want to disable the creation of actions/connectors as well if an ephemeral key is used?

I agree, I was thinking of doing those in a separate PR and only backport this PR (alert APIs) into 7.6? Happy to backport both otherwise. I will keep the main GH issue #56420 open until both API sets are fixed and backported properly.

Should we move the logic from the alerts client and move it into getAlertsClientWithRequest function below? 🤔 There's also the alerts client factory that could handle it.

This would mean we throw this error at a higher level with more ways around it but a lot less code.

Seems like the answer would be yes. Unless the encryption key can be set in the config "live" via the NP plugin live config bits. In that case, we'd need to rebuild the alerts client at the same time, at which point it would be happy with the key.

seconded 👍
That makes more sense to me too

The one holdback I have is that we expose the AlertsClient class (https://github.com/elastic/kibana/blob/master/x-pack/legacy/plugins/alerting/index.ts#L14) so others who use the class directly wouldn't be protected anymore. 🤔 We should probably just expose the interface instead of the class.

++ to pulling it up to getAlertsClientWithRequest

Ya, exposing an interface would be better, eg we could have a "disabled" version of the class which just threw errors for all the API calls, which we returned in this case, instead of the "real" one.

But it also makes me wonder if there are some APIs we should actually allow. find() and get() seem ok to me, and I'm wondering if that would be useful to have available in this case. Probably doesn't matter, since you can't really do anything else at this point anyway without fixing the encryption key config ...

@gmmorris @peterschretlen @pmuellr let me know your thoughts. I've made the changes based on the discussion we've had here: #56676 (comment).

pmuellr

LGTM

Initially, this felt kind of "blunt", I guess I was thinking we'd return an alert client that implemented all it's methods as things that threw the exception, instead of throwing when trying to get the alert client. But after seeing this, I think it's probably better, as it let's a plugin using alerting to be able to make the determination up front, instead of at every point they use the alert client. I guess we'll find out.

Was looking at our routes, and I suspect we will want them enhanced. Eg

kibana/x-pack/legacy/plugins/alerting/server/routes/create.ts

Lines 68 to 71 in 885b79e

    
           async handler(request: ScheduleRequest) { 
        
             const alertsClient = request.getAlertsClient!(); 
        
             return await alertsClient.create({ data: request.payload }); 
        
           },

Won't it throw something in that reques.getAlertsClient!() call now, that it wouldn't before? I think the result would be that you'd get a 400 "invalid request" kind of result, but it would be nice to actually indicate what the error was. Or maybe since it's security-related, it would be best NOT to. Worth noodling over a bit (separate issue), I think it's certainly survivable as-is for now.

LGTM 👍 Tested it out with the management UI and detection engine and confirmed you can't create or list alerts. Dev mode works as before with the 'aaaaa....' key, so dev experience is unchanged which is great.
