0day
Dirk-jan Mollema, a pentester working for Foxit, found a very clever attack allowing any user, owning an Exchange mailbox, to obtain Domain Admin privileges.
The attack has been unveiled last week, strangely without a lot of media coverage (but things seem to change, the daily blogpost of the SANS ISC covered the subject yesterday). As there is still no fix (think software patch to install) from Microsoft, the term “0day” is around.
