RSU

Roadside Unit (RSU) - Sybil Attack

Overview of the Vulnerability

Automotive security misconfigurations can occur within the software, firmware, or network settings of vehicles, leading to security vulnerabilities. These misconfigurations can stem from default settings, inadequate security measures, or improper configurations during the manufacturing or maintenance processes. An attacker can exploit this misconfiguration and gain unauthorised access to data, or manipulate the vehicle system's integrity.

Business Impact

This vulnerability can lead to data breaches, unauthorized access to sensitive information, remote exploitation or manipulation of vehicle systems, or compromise of driver safety, privacy, and vehicle integrity. Additionally, it may result in reputational damage, legal liabilities, and financial losses for automotive manufacturers and service providers.

Steps to Reproduce

1. Identify the software, firmware, and network components present in the vehicle: {{Vulnerable component}}

2. Analyze the configurations and settings of these components for potential misconfigurations.

3. Exploit the misconfiguration to gain unauthorized access, manipulate vehicle systems, or intercept communications.

4. Observe that it is possible to {{vulnerable action}}, demonstrating the misconfiguration.

Guidance

Provide a step-by-step walkthrough with screenshots on how you exploited the vulnerability. This will speed up triage time and result in faster rewards. Please include specific details on where you identified the vulnerability, how you identified it, and what actions you were able to perform as a result.

Attempt to escalate the vulnerability to perform additional actions. If this is possible, provide a full Proof of Concept (PoC).

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.
