一、使用说明：

1.运行环境：

Linux命令行界面+Python2.7

2.程序源码：

Vim scanner//建立一个名为scanner的文件

Chmod a+xscanner//修改文件权限为可执行的

3.运行程序：

Python scanner//运行文件

若没有携带目标URL信息，界面输出帮助信息，提醒可以可输入的参数。

参数包括：

--h 输出帮助信息

--url 扫描的URL

--data POST请求方法的参数

--cookie HTTP请求头Cookie值

--user-agent HTTP请求头User-Agent值

--random-agent 是否使用浏览器伪装

--referer 目标URL的上一层界面

--proxy HTTP请求头代理值

Python scanner--url="http://127.0.0.1/dvwa/vulnerabilities/sqli/?id=&Submit=Submit"--cookie="security=low;PHPSESSID=menntb9b2isj7qha739ihg9of1"

输出扫描结果如下：

结果显示：

存在XSS漏洞，漏洞匹配漏洞特征库“”>.XSS.

存在SQL注入漏洞，目标网站服务器的数据库类型为MySQL。

存在BLIND SQL注入漏洞。

二、源代码：

代码验证过可以运行，我个人推荐用DVWA测试吧。
