CVE-2024-23928 in DMH-WT7600NEX
Summary
by MITRE • 01/31/2025
This vulnerability allows network-adjacent attackers to compromise the integrity of downloaded information on affected installations of Pioneer DMH-WT7600NEX devices. Authentication is not required to exploit this vulnerability.
The specific flaw exists within the telematics functionality, which operates over HTTPS. The issue results from the lack of proper validation of the certificate presented by the server. An attacker can leverage this in conjunction with other vulnerabilities to execute arbitrary code in the context of root.

The vulnerability identified as CVE-2024-23928 represents a critical security flaw in Pioneer DMH-WT7600NEX infotainment systems that exposes devices to remote compromise through network-adjacent attack vectors. This vulnerability specifically targets the telematics functionality component that operates over HTTPS protocols, creating a dangerous attack surface where authentication requirements are entirely absent. The flaw fundamentally undermines the security model of the device by failing to implement proper certificate validation mechanisms during the secure communication establishment process. Network-adjacent attackers can exploit this weakness without requiring any form of authentication, making the attack surface particularly concerning given the widespread deployment of these automotive infotainment systems in consumer vehicles.
The technical root cause of this vulnerability stems from inadequate certificate validation procedures within the HTTPS implementation of the device's telematics subsystem. This weakness aligns with CWE-295, which addresses "Improper Certificate Validation," and represents a classic example of how insufficient cryptographic validation can lead to severe security implications. The device fails to properly verify the authenticity and integrity of server certificates presented during HTTPS connections, allowing attackers to potentially intercept or manipulate secure communications. This failure in certificate validation creates a man-in-the-middle attack opportunity where malicious actors can present fake certificates to establish seemingly legitimate connections with the device. The vulnerability's classification as a network-adjacent attack vector means that exploitation requires only network proximity to the target device, eliminating the need for complex remote access techniques or specialized network penetration tools.
The operational impact of CVE-2024-23928 extends beyond simple data integrity compromise, as it provides attackers with the potential to execute arbitrary code with root privileges on affected devices. This privilege escalation capability represents a severe escalation from initial access to complete system compromise, as the vulnerability allows attackers to operate within the highest privilege context of the device. The combination of the certificate validation flaw with other potential vulnerabilities within the system creates a comprehensive attack path that can lead to complete device takeover. This scenario aligns with ATT&CK technique T1059.001, which covers command and scripting interpreter, as attackers can leverage the compromised system to execute malicious code. The implications for automotive cybersecurity are particularly severe given that these devices often contain sensitive vehicle control systems and personal data, making them attractive targets for attackers seeking to compromise vehicle operations or extract confidential information.
Organizations and vehicle owners should immediately implement mitigations that include network segmentation to isolate affected devices from untrusted network segments, ensuring that only authorized network traffic can reach the vulnerable telematics functionality. The most effective immediate response involves disabling unnecessary telematics features and implementing network access controls that restrict communication to known trusted endpoints. Additionally, vendors should provide firmware updates that implement proper certificate validation mechanisms and strengthen the overall cryptographic security posture of the device. The vulnerability demonstrates the importance of robust certificate validation as outlined in industry standards such as NIST SP 800-57 and ISO/IEC 15408, which emphasize the necessity of proper cryptographic implementation to prevent man-in-the-middle attacks. Regular security assessments and network monitoring should be implemented to detect potential exploitation attempts, as the vulnerability's lack of authentication requirements makes it particularly difficult to detect through traditional access control mechanisms.
