Crash in function mg_handle_form_request() when receiving badly formed form data post. about civetweb HOT 3 OPEN

What version of the server did you use ?
I will need some information to be able to reproduce this locally. What exactly is the screenshot above showing?
is this a memory dump from the network package?
'/backup-restore' is a C handler function calling mg_handle_form_request ?

Sorry - That was a Friday end of the day post.

Hi it is version 1.16 of the server
Sorry I did not explain very well . The screen shot is Wireshark capture of the badly formed data I was sending to Civetweb embedded in one of our software products.

The /backup-restore is the URL that I have a handler installed for but it did not get to my handler.
When I fixed my javascript to correctly format the post request I did not encounter any issues.

I will see if I can produce a minimal example that cause the problem.

As a work around I added a check for NULL and that stopped the crash

If you know how the request exactly looks like, it might be possible to send it with "netcat".
I can do this myself, if I know the exact byte sequence sent.
Also, I can try if this is possible to find using a fuzz test - actually there is a fuzz test for CivetWeb, but it did not find this issue (yet).
