| Step | What we did | |------|-------------| | | Identified binary type, protections (NX, no PIE, no canary), and located the flag in .rodata . | | Dynamic analysis | Traced the input handling routine → discovered a 64‑byte stack buffer read with no bounds checking. | | Vulnerability | Classic stack‑buffer overflow allowing control of the saved return address. | | Exploit | Overwrote the return address with the address of the instruction that loads the flag address into RDI and calls puts . | | Result | Program prints the hidden flag FLAGipzz_447_is_solved and exits cleanly. | ipzz-447
