If enabled, you cannot execute shellcode on the stack; you must use ROP (Return Oriented Programming) . ASLR/PIE: Determines if memory addresses are randomized. 2. Identifying the Vulnerability

from pwn import * # Setup target = process('./download-swsec-bin') # or remote('host', port) elf = ELF('./download-swsec-bin') # 1. Leak Address (if necessary) # 2. Calculate offsets # 3. Send payload payload = b'A' * OFFSET + p64(POP_RDI) + p64(BIN_SH_ADDR) + p64(SYSTEM_ADDR) target.sendline(payload) target.interactive() Use code with caution. Copied to clipboard Summary of Flags Finding the vulnerable function in Ghidra. Dynamic Analysis: Debugging with GDB to observe the crash. download-swsec-bin

If ASLR is enabled, you may need to leak a libc address (like puts or __libc_start_main ) to calculate the base address of the C library. Construct the Payload: Padding: Fill the buffer up to the return address. If enabled, you cannot execute shellcode on the

Use a pattern generator (like cyclic ) in gdb-pwndbg to find exactly how many bytes are needed to reach the Instruction Pointer ( RIP ). Identifying the Vulnerability from pwn import * #

These do not check buffer boundaries, allowing you to overwrite the return address on the stack.
