Six vulnerabilities in Mazda’s infotainment system could be exploited via a USB, potentially affecting vehicle safety. Originating from the Mazda Connect CMU, these flaws could allow full system compromise and access to sensitive data. Though serious, real-world exploitation remains unlikely currently, highlighting the need for improved vehicle security measures.
**Meeting Takeaways: Mazda IVI Vulnerabilities**
1. **Identified Vulnerabilities**: Six unpatched vulnerabilities have been found in the Mazda in-vehicle infotainment (IVI) system that could be exploited via physical access using a malicious USB.
2. **Vehicle Safety Impact**: One vulnerability has legitimate implications for vehicle safety, potentially allowing attackers to access the Controller Area Network (CAN) bus, which is crucial for vehicle component communication.
3. **Affected Models**: The vulnerabilities primarily affect recent Mazda models, including Mazda3, CX-3, CX-5, and CX-9, which utilize the Mazda Connect Connectivity Master Unit (CMU) by Visteon Corporation.
4. **Vulnerability Details**:
– **CVE-2024-8358, CVE-2024-8359, CVE-2024-8360**: Exploit weaknesses in file extraction during software updates due to unsanitized input, enabling full system compromises.
– **CVE-2024-8357**: Addresses a problem with the boot process lacking authentication, allowing attackers to manipulate files prior to system startup.
– **CVE-2024-8355**: Users can spoof an Apple device’s serial number, executing unauthorized SQL commands and compromising system integrity.
– **CVE-2024-8356**: Tied to the software update process, it can allow an attacker to manipulate the VIP MCU, which connects to the CAN bus.
5. **Real-World Risks**: Although the theoretical risks associated with these vulnerabilities are high (e.g., unsafe vehicle operation), actual exploit scenarios remain largely hypothetical, as traditional vehicle theft methods are currently more common.
6. **Future Concerns**: The trend towards more connected vehicles increases the chance of remote exploitation, potentially leading to more sophisticated attacks. Examples include recent vulnerabilities demonstrated in other vehicles, highlighting industry-wide security challenges.
7. **Recommendation**: Vehicle manufacturers need to adopt multilayered security measures across all components to prevent exploitation, emphasizing that each module should be independently secure rather than relying on overall system defenses.
8. **Next Steps**: Await further comments from Visteon and continue monitoring the situation for potential updates or patch releases.
