eCitadel 24 "Buffer Overflow"
More or less a simple explanation of a buffer overflow and how to exploit it. This challenge is from eCitadel Open 2024 as part of one of the injects. To give some background, the challenge wanted teams to submit a document detailing the artifact name, the location of a secret function within the artifact, the buffer offset needed to overflow the return address, and the secret flag that is printed out.
To make this more interesting, I'll solve each one of the 4 challenges using a different method.
