TITLE:
Motorola Cellular Phones Security Dialog Spoofing Vulnerability

SECUNIA ADVISORY ID:
SA19319

VERIFY ADVISORY:
http://secunia.com/advisories/19319/

CRITICAL:
Less critical

IMPACT:
Security Bypass, Spoofing, Exposure of sensitive information

WHERE:
>From remote

OPERATING SYSTEM:
Motorola V600
http://secunia.com/product/8840/
Motorola PEBL U6
http://secunia.com/product/8841/

DESCRIPTION:
Kevin Finisterre has reported a vulnerability in Motorola PEBL U6 and
Motorola V600, which can be exploited by malicious people to trick
users into accepting certain security dialogs.

The vulnerability is caused due to an input validation error where
the remote Bluetooth device name isn't properly sanitised before
being used in a security dialog. This can be exploited to trick users
into accepting an incoming wireless Bluetooth connection to the
"Headset Audio Gateway" on channel 3 by including newline characters
in the device name.

Successful exploitation allows access to personal information stored
in the cellular phone (e.g. phone book entries and SMS messages).

It has also been reported that it is possible to crash the handset by
sending an overly long OBEX "setpath()" via the OBEX File Transfer
service if the attacker's device has been paired. This may reportedly
be exploited to execute arbitrary code, but has not been proven.

SOLUTION:
The vulnerability has reportedly been fixed by the vendor.
