Bof

Warmup challenge featuring a “number conversion base confusion”.

Hardest pwn challenge of the CTF. A simple vulnerability lead to a BOF, but the path to RCE was really interesting

Interesting pwn challenge regarding the exploitation of a simple stack BOF.

This challenge comes from the 3rd round of openECSC 2024. The challenge was really really interesting: the exploitation tecnique involved a buffer overflow through a really short format string vulnerability.
