Who did you find this vulnerability?

[Franklin0110]

I am quite new in this stuff and I am looking to the interesting CVEs, like this one.
Then I got to a question to this complex vulnerability...
How did you find out that this might be a vulnerability?
And how did you know how to exploit it?

This might help the new people (as me) to understand how to find these vulnerabilities in the future.

Thank you for the information.

Best Regards,

Franklin.
