XF 2.2 File health showing issues

[ashwinmk]

Suddenly, File Health check is showing issues.

We did not install anything new. How can this happen? Can this be some security flaw?

What should be our next steps?

Can this be some security flaw?

Possibly.
Contact your host and ask them to investigate if the server was breached or something else caused the files to change.

What should be our next steps?

Upload the files again.

 

[ashwinmk]

Upload the files again.

Any guide to do this? Will it not break the site?

You can easily go to your customer account and download the files again.

Is it safe to replace all the files (except addons) ?

Yes mate it should be ok

The download won't include any addons. It's the way we used to have to update xenforo. In this case it will be just re-uploading without updating.

I would also check the date on those files as this may be useful for your host our anyone investigating a server breach (not that they can't check the date themselves)

You'll definitely want to check what's actually in those files as it's common to have malicious code appended to the end of javascript files. So you'll want to replace them but have someone who knows what they're doing to analyse them first to check what's in them compared to the default versions. If they have been modified you'll need to work with your host to work out how.
