Electron Security Issues

sdetweil

@mumblebaj https is SUCH a pain in the rear, as you have to create a certificate,

cert requires a registered domain name(with a ip address) , and almost never are free, and expire and …

and self signed certs are more trouble than they are worth…

and >98% of the mirrors are internal to the house/office so no one outside can access, and <10% have any app access to the local system, (remote control and such) …

CORS is controlled by the SERVER not the client… some servers are rejecting weird client browser types (MagicMirror, not chrome or firefox), and some don’t like the 0.0.0.0 address that gets sent,
and some modules are using request (which has a problem here, one of the reasons for its deprecation) and some modules are using axios/… which are enforcing more…
and electron is changing too…

@sdetweil Yep, understood. node-fetch has also had some changes which could cause some issues in future. I am trying to see if I can fix the MMM-Hue module and it calls out to a bridge which sits on the local network and runs into this CORS issue. Other modules have the same issue. This is going to make module dev a bit difficult, but I am sure we will adapt. :smiling_face_with_sunglasses:

@mumblebaj

the warnings are normal, see https://github.com/electron/electron/blob/main/docs/tutorial/security.md#electron-security-warnings and you can disable them

@sdetweil

I agree that https is a pain but I think we will be forced to use it

@mumblebaj

I am trying to see if I can fix the MMM-Hue module and it calls out to a bridge which sits on the local network and runs into this CORS issue.

I see no chance to do this in the module. I found a first (ugly) workaround and will post this in the other thread later …

Thanks @karsten13. Will await your post there. I am rewriting the module but am running into all kinds of issues. It is ugly. :-(

@sdetweil Have you seen these errors before? Mirror still starts though. I have just noticed it now as I usually start my mirror from the cron.

@mumblebaj looks like MagicMirror-backup-restore is in the modules folder… should be in the users root, as it’s not a MagicMirror ‘module’

mv ~/MagicMirror/modules/MagicMirror-backup-restore ~

@sdetweil Thanks Sam. That sorted it.

Recently I have only started coding and therefore do not pay attention to security bugs at all. I hope that it is not interesting for anyone to hack into our computer.

oh joy

@sdetweil And so it begins. Modules like the MMM-Hue and others that talk to internal devices on the local network is going to become a problem.
