	remote code execution

heh,

I have seen worse cases.  I had to go into a Hospital one night to get a
few x-rays done, I'd say around 9pm or so.  Ok, so on the way in being
accompanied by one of the nurses I noticed that a cleaning person was
tidying up a bit around the x-ray rooms, etc... ok thats cool I
thought.  But on the way out, I noticed that the person was in a
different area of the facility tidying up around terminals STILL logged
in and not screen locked or logged out.  Go figure.
