Vista Exploit Surfaces on Russian Hacker Site

Posted by Zonk on from the exploits-show-up-in-the-funnest-places dept.

Datamation writes "Exploit code for Windows Vista (though at this point only proof-of-concept code) has been published to a Russian hacker site, Eweek reports. Certain strings sent through the 'MessageBox' API apparently cause memory corruption. Though this is obviously cause for concern, at the moment it would seem access to the system would already be required to make use of the exploit. Determina has an analysis of the bug. Just last week, Trend Micro reported that Vista zero-days are being sold at underground hacker sites for $50,000."

    Obviously Microsoft is missing these holes in Vista in house.

    Maybe the biggest customer for these zero-day exploits should be.. Microsoft?

    $50,000 isn't that much compared to the other option IMHO.

    Just a thought.

    ... from another russian forum (roughly translated from russian...)

    Function GetHardErrorText
    Comment:
    * This function figures out the message box title, text and flags.
    * We want to do this up front so we can log this error when the hard error is
    * raised. Previously we used to log it after the user had dismissed the message
    * box -- but that was not when the error occurred (DCR Bug 107590)

    This function finds and extracts strings like "{EXCEPTION}" from MessageBox's text and if found, writes them in the system log.

    } else if ((asLocal.Length > 4) && !_strnicmp(asLocal.Buffer, "\\??\\", 4)) {
    strcpy( asLocal.Buffer, asLocal.Buffer+4 );
    Local.Length -= 4;
    Say, nice use of strcpy...

    A smart black hat would lay low until SP1 is released, and wait for the real corporate deployment to begin.

    A smart black hat has like a job and a life.

    The only thing I can say that these script kiddies and whatnot are good for is that they are easily detectable and they alert security people of vulnerabilities so that it makes it difficult for people that are really interested in doing real damage or obtaining data that they shouldn't have.

    Its really ironic how valuable these kids are. Without them, real compromises would be more common and much more painful.
