No Fixes In Sight For Satellite Terminal Flaws


At Black Hat USA, a researcher who in April revealed weaknesses in popular satellite ground terminal equipment found on air, land and sea, demonstrates possible attack scenarios.



BLACK HAT USA -- Las Vegas -- Back in April, when security researcher Ruben Santamarta 
first went public with serious security flaws in the firmware of satellite land equipment
 that could allow attackers to hijack and disrupt communications links to ships, airplanes, and military operations, only one of the affected vendors had responded to his findings.
Santamarta in a presentation on his research here Thursday at
Black Hat USA
said the satellite terminal vendors with gaping holes in their products have no plans to patch or fix the shortcomings, which include hardcoded passwords, backdoors, insecure protocols and undocumented protocols. Some contend that the issues are not flaws but acceptable features in their products. Santamarta reported his findings to the CERT Coordination Center, which then alerted the satellite vendors in January of this year.
Hughes, for example, stated that the digital backdoors are a normal and common practice in commercial products for retrieving lost or forgotten passwords, says Santamarta, principal security consultant with IOActive.
I expected to find some security issues [with these devices] but the backdoors and ability to upload software without authentication, these things are very serious, Santamarta told Dark Reading.
Specifically, he found that an attacker could completely compromise the systems, run malware, install malicious firmware and even send an SMS text to spoof the communication to a ship, for example. They can spoof messages and trick the ship to follow a certain path, or to rescue another ship. They can disrupt communications... if a vessel cant send a distress signal, thats the worst scenario, if a ship cant communicate, Santamarta explained in an April interview after his initial findings were first published.
In the case of an airplane, the in-flight airline WiFi network is vulnerable to malicious behavior, he says, because the Cobham AVIATOR 700 satellite terminals sit on the WiFi network. The danger, he says, is an attacker gaining control over the Satellite Data Unit or the SwiftBroadband Unit interface by taking advantage of the weak password reset feature, hardcoded credentials or the insecure protocols in the AVIATOR 700.
More specifically, a successful attack could compromise control of the satellite link channel used by the Future Air Navigation System (FANS), Controller Pilot Data Link Communications (CPDLC) or Aircraft Communications Addressing and Reporting System (ACARS). A malfunction of these subsystems could pose a safety threat for the entire aircraft, writes Santamarta in his white paper on the findings.
But were not crashing planes here, Santamarta says. Even so, disrupting ACARS messaging could pose a safety risk, he says.
Cobham said an attacker would need physical access, or the network would have to have been improperly installed, for the attack scenarios Santamarta presented. The company also said over-the-air communications requires user authentication, and hardcoded passwords cannot be used.
With any of the vulnerabilities in the various satellite terminals, the attackers would have to have some knowledge of the inherent firmware and its weaknesses, as well as how to exploit them.
Santamartas findings mirror that of many other so-called embedded commercial systems. Billy Rios, director of threat intelligence at Qualys, here yesterday revealed his latest findings on Transportation Safety Administration (TSA) checkpoint systems, namely that the TSAs Kronos 4500 time clock system used by TSA agents to clock in and out with their fingerprints, contains two different hardcoded passwords that can only be changed by the vendor.
A lot of embedded systems have lame vulnerabilities. Name your embedded system, its going to have some basic security weakness, says Marc Maiffret, CTO at BeyondTrust.

Santamarta studied and reverse-engineered the firmware of satellite terminal equipment from Cobham, Hughes, Inmarsat, JRC, Iridium, and Thuraya. 
If you have physical access to any of these devices, its over, Santamarta says. You can compromise all the devices on that network, he says.
Security experts say hardcoded credentials in hardware is a recipe for disaster. Using hard-coded username and passwords from hardware manufacturers without another layer of protection is security suicide, says Ken Balich, CISO at Authentify. All of these vulnerabilities and breaches stem from two things:  failures in network security thinking to understand and counter emerging threats, and following the old adage I dont need more security until something happens.  Unfortunately thats too late and many can pay a steep price.
