Advisory ID        : NETRAGARD-20090427
Product Name      : GoGo Inflight Internet
Product Version      : Unknown
Vendor Name      : Aircell LLC.
Type of Vulnerability    : No link layer security option
Impact          : Varies
Vendor Notified      : 20090427

[Product Description]
------------------------------------------------------------------------------------------------------
"As a service of Aircell LLC, Gogo provides all passengers access to the
Internet, email, text messaging and corporate VPNs from the comfort of
their seats while airborne. Aircell has been authorized by the FAA and
FCC to use cellular frequencies for inflight broadband communications,
leading a Wi-Fi revolution 35,000 feet above the ground. Think of it as
a mobile hotspot, equipped with twin turbines and 50,000 lbs of thrust.

Partnering with a variety of carriers, Gogo provides coast-to-coast,
border-to-border connectivity for all passengers. Launching with  
American
Airlines in 2008, Gogo will continue to expand, giving everyone the
ability to stay in touch, in flight®."

[Technical Summary]
------------------------------------------------------------------------------------------------------
The GoGo Inflight Internet service does not encrypt wireless connections
between GoGo Inflight Internet users ("Users") and the GoGo Inflight
Internet Wireless Access Points ("WAP"). As a result any Users  
connection
can be intercepted by another user and the data that they transmit can  
be
stolen or their respective connections can be hijacked.

[Impact]
------------------------------------------------------------------------------------------------------
[Impact varies from installation to installation]

- Theft of customer data
- Access to business networks
- Infection of Users computer systems
- Theft of personal information
- Theft of Social Security Numbers
- Theft of Credit Card numbers
- Manipulation of in-transit data
- etc.

[Proof Of Concept]
------------------------------------------------------------------------------------------------------
Connect to GoGo Inflight Internet on your next flight and you will see  
that
the connection between your device and the WAP is not encrypted.  
Connecting
does not require paying for the service, it only requires establishing a
connection to the WAP.

Important Notes:
------------------------------------------------------------------------------------------------------
Because this vulnerability exists at the link layer it is possible for  
an
attacker to defeat or subvert a users SSL based connection. This  
subversion
would enable the attacker to capture credit card information or any  
other
information submitted over the web.

It may also be possible to subvert, defeat or hijack VPN connections as
the attacker can interfere with the entire connection process.
