This looks like fun: fundamental security flaw in Windows that cannot be patched Full PM-box? Change here!

"Unfixable" flaw breaks Microsoft's Windows

quote:

The flaw is part of the fundamental design of the Windows operating system. It is contained within the mechanism that controls the flow of messages between different windows on the desktop. This is called the Win32 API and has remained unchanged since 1993.

Critically, the Win32 API system does not authenticate the messages, so cannot distinguish messages from malicious or legitimate sources. This allowed Paget to select a window with the highest privileges and surreptitiously embed a malicious piece of code. When executed, the code would increase his user privileges to the maximum given to that window.


So what's the latest news on this? Has anything been done about it?

And the article is a bit misleading as to how serious this really is.

  • On XP, most users log in as Administrators anyway. So what's the point of an exploit that lets you run code as an administrator when users run it like that intentionally most of the time?
  • LocalSystem is far less useful than they imply - LocalSystem is a typical account that can also pretend to be run from other accounts on a thread-by-thread or whole process basis. Even so, this requires a username/password for said accounts.

    They also don't mention that this is a common "flaw" in OSes, including Linux.

    For example:
    quote:
    make a copy of a shell program (e.g. csh, bash, sh,
    ksh, whatever) in your user area. Write some code that figures out where the
    inode table (which is usually cached in RAM) entry for that file resides in
    memory. Trap into a debugger, and set the suid root bit for that file.
    Resume the operating system. Run the shell - you now have a command prompt
    with root privileges.

    i don't think most people realize they are running it as an administrator. after all, when they run setup, they see an "administrator" account, and then it asks for their name.

    most people probably don't realize they have all the power of a superuser...

    they may not realize such power exists, st leo. not to downplay the intelligence of the average computer user, but i've found that while working in tech support, most users have no idea that their default windows account has administrator priviledges. things install for them, and that's all they care about. they naturally don't know how to use "services" or "computer management", nor do they often bother with "internet options", "control panel", and the like--which are all accessible on the default named account.

    Yes. However, they are "administrators" on their own boxes only with that logon. They are not administrators on remote boxes or on NT/2k domains unless granted those priveleges separately in the appropriate places.

    The reason XP defaults new accounts to administrator is for ease of use considerations.

    Most games and applications when XP launched required administrator privledges to install because of how Win9x was designed. It'd be a huge pain in the ass (and confusing) for most people to have it tell you that you need an Administrator account to install a simple game.

    Most games and apps out right now are properly configured and install on a per-user basis rather than per-system, so they do not require administrator accounts.

    In Longhorn, not only will a limited account be the default, but .NET apps will more than likely far outnumber old Win32 apps.

    Panag, OS X is succeptible to the same thing thanks to its Unix heritage.

    Try it yourself:

    I've determined I'll never understand why people buy Macs, because there is no real sense in it.

    It's all about emotions and what they're used to. If they're happy paying huge gobs of money to Apple for that, so be it.

    So yes, I have wondered why, there's just no real answer aside from "it's purty".

    On the same line of thought, I'll never understand why people buy Land Rovers.
