Online Booking System Flaw Affects 141 Airlines
TRANSPORT INDUSTRY

The Amadeus ticket booking system contains a vulnerability that allows anyone to access and change private information on flight bookings. The ticketing system is used by 141 international airlines, which represents about 44% of the global online reservation market. The booking system exposes the Passenger Name Record (PNR), which provides access to the passengers' names and associated flight details. Using the PNR code, a user can login to the customer portal to change or cancel flight reservation, claim frequent flyer miles, assign seats and meals, and update customer's email and phone number. Amadeus has since rectified the flaw in its online reservation system after being notified.
