Superfast (HackTheBox)

Hey folks. In this write-up, we're going to discuss the Superfast challenge in HackTheBox which was part of the HackTheBox Business CTF 2022. We're going to perform a single-byte overwrite to bypass ASLR, leak stack pointers, and perform a Return Oriented Programming (ROP) chain. The description of the challenge is:
