Python脚本实现Web漏洞扫描工具

这是去年毕设做的一个Web漏洞扫描小工具，主要针对简单的SQL注入漏洞、SQL盲注和XSS漏洞，代码是看过github外国大神（听说是SMAP的编写者之一）的两个小工具源码，根据里面的思路自己写的。以下是使用说明和源代码。

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

例如扫描"http://127.0.0.1/dvwa/vulnerabilities/sqli/?id=&Submit;=Submit"

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.<""，属于嵌入标签外的类型。

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。
