Subject: [Braillenote] Warning: BrailleNote Apex Offers 
Read/Write FTP AndTelnet Access To All Comers

BrailleNote Apex offers telnet and FTP access on the standard 
ports, with read/write privilege on the entire file system, to 
all comers.  No authentication is required.  BrailleNote is 
unsafe on any network whose devices you are not in full charge 
of, and which (by NAT or firewall) does not protect BrailleNote 
from the Internet.

I am happy and sad.  In a chance port scan of my entire network 
looking for interesting services and protocols that were not 
accounted for by visible configuration options in all my devices, 
I found this disaster staring me in the face on the least likely 
candidate of them all.  On the one hand, now I don't need 
ActiveStink in order to access my files, over the network, from 
my Mac.  I want these services running, for sure (maybe just FTP) 
but dammit, authentication first!  On the other hand, there is no 
doubt my trust in HumanWare is badly dented, as I was clearly 
optimistic that they would, and did, do the right thing and 
secure the device firmware before shipping it.  Anonymous FTP and 
telnet are obvious, easily found and effectively exploited.  If 
it isn't configurable, it shouldn't be enabled.  I am quite sure 
this was the case before now.  The most likely explanation is a 
build with a test configuration and services for development 
still in use on the newest model; the USB vendor string is 
further evidence of this.  Note to self: that popular expression 
about assumptions turns out to be true.

KeySoft version 9.0.2 build 756, Windows CE 6.0, with telnet and 
FTP services.

While we await an update that either disables the services or 
allows the user to specify the authentication credentials, do not 
use your BrailleNote Apex on any untrusted network, or if you are 
network administrator, temporarily prohibit these devices from 
connecting to your networks.  If "Bad guys" are on your network, 
the BrailleNote Apex is, alas, easy meat.

Cheers,
Sabahattin
