Intercept Request that Accepts Null Values

NSB | Last updated: Sep 02, 2022 10:10AM UTC

On body I have json like following: "date":{"id":null,"newDate":"2022-09-02","code":32} Previously, I tested the site and there was flaw on the id value that I can be changed to previously used id and the its date and code could be replicated.. and sent to the server without any issue. Now after Site Update, the id is null everytime and I cannot use the previous id value and those code and date are something like constant, Whatever value I put it into the code doesnot gets changed on submit. What shall I look here now in order to find out bug on this that will allow user to manipulate code or enter id that has. been stored on the Database previously.?

Thanks for your message. You mentioned in your description that the site had been updated. Is it the web application itself that has been updated, or has something else changed?

No I mean they had fixed that issue now. I cant change just the ID and POST. They had made changes in such a way that it must be null for id on POST.
