A Critical Vulnerability in BYD QIN PLUS DM-i's Dilink OS
CVE-2024-54728
CVE-2024-54728 is a security vulnerability identified in the BYD QIN PLUS DM-i vehicle's Dilink OS 3.0_13.1.7.2204050.1. This flaw arises from incorrect access control, which allows unauthorized attackers to gain access to sensitive system logcat logs, potentially exposing confidential vehicle data and compromising user privacy.Technical Details
The vulnerability is characterized by its ability to bypass permission restrictions, enabling attackers to retrieve log data that should be secured. Logcat logs typically contain detailed information about system operations, errors, and other critical events that can provide insights into the vehicle's functioning and user interactions.Key Metrics
- Vulnerability Type: Incorrect Access Control
- Affected Software: BYD QIN PLUS DM-i Dilink OS 3.0_13.1.7.2204050.1
- Potential Impact: Unauthorized access to system logs
Sample Scenarios
Scenario 1: Unauthorized Access to Vehicle Logs
An attacker exploits CVE-2024-54728 by sending crafted requests to the vehicle's system, bypassing authentication mechanisms. As a result, they can access logcat logs that contain sensitive information such as GPS data, user commands, and error reports. This could lead to the exposure of personal driving habits or even location tracking.Scenario 2: Data Exfiltration
In a more advanced attack, an unauthorized user could automate requests to extract extensive log data over time. By aggregating this information, they could build a comprehensive profile of the vehicle's usage patterns, which could be sold or used for malicious purposes.Scenario 3: Compromised User Trust
If users become aware that their vehicles are susceptible to such vulnerabilities, it may lead to diminished trust in the manufacturer and its products. This could result in reputational damage and a potential decline in sales.Mitigation Strategies
To address CVE-2024-54728, it is crucial for manufacturers and users to implement the following strategies:- Software Updates: Ensure that all vehicles are updated with the latest firmware that patches this vulnerability.
- Access Control Enhancements: Strengthen authentication mechanisms to prevent unauthorized access.
- User Awareness: Educate users about potential risks associated with vehicle data security and encourage them to report suspicious activities.
