UnAuthorized Access To Services
Unauthorized Access To Services
Overview of the Vulnerability
The In-Vehicle Infotainment (IVI) system is a central unit in an automotive vehicle's dashboard that centralizes information and entertainment systems and their controls. Misconfigurations in the IVI system can lead to security weaknesses. Unauthorized access to services in the IVI system can originate from wireless protocols, in-vehicle applications, and physical inputs that communicate with the vehicle’s IVI unit. An attacker can leverage the unauthorized service(s) to escalate privileges on the IVI unit, and compromise internal and external communications.
Business Impact
Exposed services that are accessible from within the IVI system can result in reputational damage and indirect financial loss for the business through the impact to customers’ trust in the security and safety of the automotive vehicle.

Guidance
Provide a step-by-step walkthrough with a screenshot on how you exploited the vulnerability. Your submission must include evidence of the vulnerability and not be theoretical in nature. For an infotainment vulnerability, please include detailed instructions that can be followed to easily demonstrate and reproduce the issue. If data was found using Open Source Intelligence (OSINT), please provide steps to where and how it was found.
Attempt to completely stop the vehicle from functioning if the infotainment system controls a mechanical aspect of the vehicle. If this is possible, provide a full Proof of Concept (PoC) here.
Recommendation(s)
There is no single technique to remediate automotive security misconfigurations. However, implementing the right combination of defensive measures can prevent and limit the impact. Some best practices include the following:
Develop and enforce secure configuration guidelines for the automotive system, incorporating guidelines for software, firmware, and network settings.
Ensure that the vehicle's firmware is regularly updated with security patches and fixes to address known vulnerabilities and misconfigurations.
Conduct regular security audits and assessments of the vehicle's configurations to identify and remediate any misconfigurations. Follow industry best practices and benchmarks for these.
