On every Cart32 installation I have looked at, cart32clientlist will accept
any string or nothing at all.
No password is required to view the client list and password hashes.
Does hexing 'wemilo' out of the exe prevent this?
Also, I have seen one site where they edited the HTML of cart32clientlist
like this:
<input type=password name="xxxxxxx">
This is useless and does not prevent anyone from creating a local copy
with a full path to cart32.exe and a valid input field like this:
<input type=password name="Cart32Password">
