前言

iwebsec靶场的SQL注入漏洞的第03关bool注入漏洞渗透，

一、源码分析

如下所示，SQL语句为$sql="SELECT * FROM user WHERE id=$id LIMIT 0,1";

可知这是一个普通的数字型注入，并且没有对参数id做任何过滤

不过在输出内容中可以得知仅sql查询成功时有正确输出welcome to iwebsec!!!

当sql查询结果错误时显示1

也就是说这属于布尔型注入，形象的描述就是当前页面只会点头或者摇头，仅有这两种表达方式，也就是布尔的是与否两者形式，故而是布尔注入。

二、sqlmap渗透

1.注入命令

sqlmap -u http://192.168.71.151/sqli/01.php?id=1  --current-db --dump --batch

如下所示渗透成功，发现其存在布尔型盲注漏洞

2.完整交互过程

kali@kali:~$ sqlmap -u http://192.168.71.151/sqli/03.php?id=1 --current-db --dump --batch

总结

通过源码再来分析下布尔型SQL注入重点内容：

（1）闭合方式是什么？iwebsec的第03关关卡为数字型

（2）注入类别是什么？这部分通过源码分析与手注很容易判断出是布尔型注入

（3）是否过滤了关键字？很明显通过源码，iwebsec的布尔型关卡无过滤任何信息

了解了如上信息就可以针对性进行SQL渗透，使用sqlmap工具渗透更是事半功倍，以上就是今天要讲的第3关bool注入内容，初学者建议按部就班先使用手动注入练习，再进行sqlmap渗透。
