    Yeah, I know it's not a new BUG, but still work.

    I've read the BID 933, and I saw that there isn't a away to exploit
    this, so...

    Step by Step:
    1 - find a admin's mount point(a.k.a. home directory);
    2 - place the autorun.inf and autorun2.exe on there;
    3 - drop the admin's connection(use your prefered DoS tool);
    4 - try to connect as user nelson and password nelson;
    5 - BINDO, you are now a member of "Administrators" group(Stand Alone
    Servers) or
    "Domain Admins" gourp(PDC Servers).

    If you get a look in code, it's possible to make it more usefull making
    some teste, like findo PDC in domain or some others decision, easy and
    automatic.

    PS: It still works in some of Penetration Testes I have made, so it's
    possible usefull for all of you, I hope.

    PPS: It's not just a "Privilege Escalation", it's possible to create a
    new account with "Administrator/Domain Admin" privilege, obscurity.

    Sem mais,
