hi list,

you can workaround this 'problem' and protect yourself against an
intruder, by patching your registry file :

(Do it at your own risks : )

HKLM\SOFTWARE\Microsoft\Internet Explorer\View Source Editor\Editor Name

and set the default key to 'c:\windows\notepad.exe' (or any editor you
wanna use, providing the full path).

Even better: rename any exe to notepad.exe ;)

Is this IE being so stupid as to run with a CWD of Desktop and
effectively doing a system("notepad")?

  Yep.

That'd explain explorer opening up folders called Notepad, and .exe files
being run.  Bet it also works on MS Word documents (without a .doc
extension, probably), and any other magically executable file...

Certainly cmd.exe as notepad on the desktop suggests the CWD is your
Desktop (so presumably IE's CWD is also Desktop).

  Yep.  You can't see that it's the cwd, but process explorer will show you
it has a handle to desktop open.

Are there any other external apps IE is stupid enough to run without a
full path prefix?  That could be fun too!  :-)

  Dunno, but I'll tell you something I spotted the other day.

  Copy calc.exe to the root of your C:\ drive, and rename it to
"Program.exe".

  Fire up a recently-updated RealPlayer.  Watch two instances of calc.exe
appear.  Close RealPlayer again.  Watch two more instances of calc.exe
appear.

  Another un-quoted path with spaces in it.  Phj33r!

     cheers,
        DaveK
