DESCRIPTION:
Kevin Finisterre has reported a vulnerability in WIDCOMM Bluetooth
Connectivity Software, which can be exploited by malicious people to
bypass certain security restrictions.

The vulnerability is caused due to an input validation error in the
handling of file uploads to the "Bluetooth Exchange Folder". This can
be exploited to upload files to locations outside the default upload
directory via directory traversal attacks through a wireless
Bluetooth connection.

The vulnerability has been reported in version 1.4.2 on the BTW
platform (using the dongle Ambicom BT2000C-US). Other versions may
also be affected.

SOLUTION:
Versions 4.0.1.700 and 3.0.1.905 are reportedly not affected.

Restrict access to the wireless Bluetooth interface.
