QUESTION
I am working to remedy some security vulnerabilities from a penetration test. The vulnerability in question is a "Web Server Vulnerable to HTTP Host Header Attack" with a recommendation of "...the Host request header is user specified and shouldn't be trusted. Ensure that strict white listing is used to validate the Host header."
I am currently using React.js as my frontend frame work and Firebase for Functions (Node.js), Hosting, Authentication, Storage and Analytics. I am not understanding from my general internet search where or even what I should be changing to remedy this vulnerability? I am gathering that I may be using code in my server calls that is using the raw "HOST" variable, but I don't see anywhere in my code this is accessed explicitly. I do have an functions.https.onCall() function, which is maybe using the HOST internally. Obviously have many onCreate(), onUpdate(), etc calls. Maybe it is another function or library I am using behind the scenes?
What is the solution to prevent host header attacks on Firebase?

...ANSWER
Answered 2022-Mar-15 at 02:37If you are using Firebase Hosting, the report it likely referring to the fact that the Host header is used to route requests to the appropriate site. This is working as intended -- since Firebase Hosting is a multi-tenant service, the Host header provides necessary information to disambiguate between sites.
No action should be necessary on your part - Firebase already carefully validates the header against known sites.

QUESTION
I want to import data from a CSV file to spring controller, as far as I know, there are 2 ways:
- parsing the data on the client side with a library like papaparse.v.v then sending it to the controller
- uploading the file and then parsing it on the server side which is the best way in the above two ways, thanks a lot
ANSWER
Answered 2021-Dec-08 at 03:45Each way also have pros and cons.
If you have only few user/client then parsing at server maybe more suitable.
Otherwise, parsing at clients should be consider because it reduce the workload at server. It should be consider with priority if your application have thousand or million request each day.
QUESTION
I have been building a simple online store using React.js (framework) and Firebase (Hosting, Firestore, Functions, and Distributed Counter extension). I am struggling with the simple ecommerce feature to increment and assign a unique order # to each new order placed. I thought I fixed an issue where if 2+ orders are placed too quickly in succession, the backend will read the current order # then set the new order # for this order, but since two orders were placed so close together, the order # given to each order is the same. The distributed counter seems to still be working, as it is always summing the 'placed' counter properly. I found recently that this issue still existed when I quickly placed two orders in two web browser windows on my local machine.
Has anyone successfully used the Firebase Distributed Counter extension to increment then assign order numbers to orders? My setup is a bit different that the example they use which is for "visits" to "pages", mainly just on "placed" counter not being on every "order" just on my "stats" order doc.
Is it impossible to remove that slight delay of reading? I feel there has to be a work around! I was thinking maybe incrementing each order by 10 instead and adding a random number between 0-10 to that, so if there were duplicates, its a low chance they both get randomized to the same sub number (i.e. order #44 and order #48), but this feels like a janky fix, as there is still a chance they are the same.
Related: I am currently getting this error with the Counter Extension on the backend and am working with GCP on fixing, but my guess is it's an issue with their end: https://issuetracker.google.com/194948300

Answered 2021-Nov-10 at 09:37The main problem with counters is the limit mentioned here:
In Cloud Firestore, you can only update a single document about once per second, which might be too low for some high-traffic applications.
also here:
You should not update a single document more than once per second. If you update a document too quickly, then your application will experience contention, including higher latency, timeouts, and other errors.
For best practices, please see Cloud Functions best practices.
On this documentation, it explains how you can workaround this limitation using distributed counters. Here's an example:

I'm trying to use PapaParse to pull from a Google Sheets CSV which has lat/lon and some options for setting markers with different icons in Leaflet. Everything appears to be working fine. The markers get set correct with the correct color from the CSV. The problem is that the icons aren't loading, even though the console log shows them as parsing correctly.

QUESTION
I have an Ionic React app and want to download data as CSV. Therefore I added react-papaparse, but I am unable to download the data with the app. As soon as I try it in the browser, it works fine.
In the end, I want to be able to fetch data stored on the phone, convert it from JSON to CSV, and then download it to the phone. I tried it as well with my fetch data as with a dummy array. Neither worked.
But when I click the button inside the browser, I am able to save the generated CSV file. Therefore I think my basic code is working, I am just missing a piece to make it work on the phone/emulator (android studio).
...ANSWER
Answered 2021-Sep-21 at 15:05Make a test page that eliminates everything except the code you want to focus on. That way you can concentrate on implementing file download.
