Subject: Bypass user GPO in Windows Xp / 2003
During some security testing in a high security enviorment - I
discovered that by using the "run as" or "the runas /noprofile" I could
bypass user GPO settings completely.
I e-mailed the security mail at Microsoft about it - and they confirmed
that they had reproducedc the behavior - but said that the user
restrictons where not ment as security settings - but just to stop the
user from messing up their enviorment !?!?!?!
To reproduce it:
Set up a domain with strict security settings. Eg. Software restritions
policies, hide local drives, remove "run", disable cmd.exe and so on.
Log on to an XP computer in that domain - make a link to cmd.exe -
select "run as" on that link.
Logon with another user in the same domain - with the same restrictions
- you'll see that the GPO's will not be loaded for that user.
Maybe not a big deal - but I thought you should know......
