Vulnerability in the Ticket Booking System

Researcher uncovered this vulnerability by analyse the link he received that associated with ticket booking system(PNR: https://fly.elal.co.il/LOTS-OF-NUMBERS-HERE.)

Here, by changing the RULE_SOURCE_1_ID, researchers access any customers PNR and access the customer name and associated flight details.

It was made the process easy to log into ELAL’s customer portal With the help of PNR and customer name and anyone could make changes..

“This control allows claim frequent flyer miles to a personal account, assign seats and meals, and update the customer’s email and phone number, which could then be used to cancel/change flight reservation via customer service”

Researchers from Safety Detective research lab execute a simple script that exposed the PNR numbers and was able to find active numbers in Amadeus.

Another non-threatening script proves that the system was vulnerable to brute-force attack due to lacking captchas and passwords protection security systems.

Amadeus replied, “At Amadeus, we give security the highest priority and are constantly monitoring and updating our systems. Our technical teams took immediate action and we can now confirm that the issue is solved. To further strengthen security, we have added a Recovery PTR to prevent a malicious user from accessing travelers’ personal information. We regret any inconvenience this situation might have caused.”
