: The first 16 bytes of the payload were used to point the RDI register toward a "slack" space in memory.

This write-up covers the second part of the challenge from CSAW CTF, focusing on the exploitation of a recursive data structure to achieve code execution. Challenge Overview : The first 16 bytes of the payload

The exploit was verified using to step through the turtle traversal logic. A critical finding during this phase was that the RBP (Base Pointer) register did not land at the expected offset, requiring a slight adjustment to the slack space to ensure the magic gadget was reached successfully. Challenge Overview The exploit was verified using to

The core of this stage involved crafting a precision payload that aligned with the program's expectations of the turtle structure while redirecting the instruction pointer.

: A 64-byte ( 0x40 ) buffer of null bytes provided a safe landing zone for the program's internal processing.

: Using the leak obtained previously, the payload had to account for specific register offsets. Payload Structure :
