CVE-2021-4034 - A Golang implementation of clubby789's implementation of CVE-2021-4034

CVE-2021-4034

January 25, 2022 | An00bRektn

This is a golang implementation of CVE-2021-4034 based on (read as: blatantly stolen from) clubby789's implementation of the vulnerability discovered by Qualys.

I made a blog post going into further detail about the vulnerability, mainly for myself, but for anyone who wants a more drawn out explanation, which you can find here.

FAQ

How are you doing?

Good, thanks for asking 😊

Did you discover this vulnerability?

No. This was from Qualys. Did you not read the first part?

Why clubby789?

Saw them create a new repository in my GitHub feed and decided I'd try to recreate it in another language (yes I have nothing better to do).

Why Golang? Shouldn't you just use C?

I just wanted to get some more Golang practice in. Also, currently not smart enough to figure out the exact details of the vuln without looking at a PoC. I get it now, but I needed to copy the code to understand the code.

Who asked?

idk
