Kia's Web Portal Vulnerability: A Wake-Up Call for API Security

Written by Security Journey/HackEDU Team | Oct 4, 2024 1:51:13 PM

The automotive industry just got a stark reminder that "connected" doesn't just mean convenience but also a whole new world of security risks.  

From Wired: Millions of Vehicles Could Be Hacked and Tracked Thanks to a Simple Website Bug 

Security researchers recently uncovered a vulnerability in Kia's web portal, the gateway to managing connected car features. This wasn't some complex hack involving CAN bus manipulation or ECU exploits. Nope, this was a simple web vulnerability, the kind that secure coding training tackles head-on. 

 

Kia's Vulnerability: A Breakdown of the Risks 

The attack surface widens dramatically as cars become more reliant on software and internet connectivity. It's no longer just about the physical vehicle; it's about the web portals, the APIs, and the entire ecosystem of code that makes these connected features possible. Like any other web application, these systems are vulnerable to common exploits if not built with security in mind. 

In Kia's case, researchers were able to bypass access controls and send commands directly to vehicles, enabling them to track location, unlock doors, and even start the engine.  

Here's a breakdown of the specific vulnerabilities they exploited: 

  • Web Portal Vulnerability - Kia's web portal for managing connected car features lacked proper access controls, allowing attackers to reassign control of vehicles' connected systems to their accounts. 
  • API Exploitation - The researchers were able to send commands directly to the API, bypassing checks that should have restricted access to authorized users like dealers. This enabled control over cars' connected features (unlocking, starting ignition, tracking location). 
  • VIN Exposure via License Plates - Attackers could easily retrieve a vehicle's VIN from its license plate using online tools like PlateToVin.com, further facilitating the attack. 
  • Wide Access to Personal Data - The vulnerability allowed access to personal information of Kia customers, such as names, emails, phone numbers, home addresses, and driving routes—posing a significant privacy and data breach risk. 
  • Inadequate Dealer Access Controls- Dealers had excessive control over vehicles, even those not on their lot, which hackers could exploit to reassign car features remotely. 
  • Potential for Theft and Harassment - Hackers could unlock vehicles, track their location, and access contents without driving them away, potentially enabling theft or harassment of car owners. 
  • Risk of Mass Exploitation - The ease of exploiting these vulnerabilities through simple web bugs and the ability to affect millions of vehicles presents a large-scale threat. 

The Kia vulnerability is a wake-up call for the automotive industry and any industry building connected systems.  

 

The Kia Vulnerability: A Textbook Case for Secure Coding 

Secure coding is the foundation of secure software development. Organizations can significantly reduce their risk of security breaches by equipping developers with the knowledge and skills to write secure code.  

Investing in secure coding training is an investment in the security of your products, customers, and brand reputation. It's also an investment in the future as the world increasingly relies on connected devices and systems. 

Some key secure practices that are important here are: 

  • Input Validation - Prevent malicious data from being processed by the application. 
  • Proper Authorization - Ensure only authorized users can access sensitive functions. 
  • Data Protection - Safeguard customer data with encryption and other security measures. 

These are fundamental principles of secure coding, and they're essential for building secure connected car systems.
