CVE-2025-14346

Comprehensive Technical Analysis of CVE-2025-14346

1. Vulnerability Assessment and Severity Evaluation

CVE ID: CVE-2025-14346 CVSS Score: 9.8

The vulnerability in WHILL Model C2 Electric Wheelchairs and Model F Power Chairs involves a lack of authentication for Bluetooth connections. This flaw allows an attacker within Bluetooth range to pair with the device and issue commands without any credentials or user interaction. The high CVSS score of 9.8 indicates a critical vulnerability due to the potential for severe impact on the physical safety of users and the ease of exploitation.

2. Potential Attack Vectors and Exploitation Methods

Attack Vectors:

• Proximity Attack: An attacker within Bluetooth range (typically up to 10 meters, but can be extended with specialized equipment) can exploit the vulnerability.
• Man-in-the-Middle (MitM) Attack: An attacker can intercept and manipulate Bluetooth communications between the device and its legitimate controller.

Exploitation Methods:

• Pairing and Command Execution: The attacker can pair with the device and issue movement commands, override speed restrictions, and manipulate configuration profiles.
• Denial of Service (DoS): The attacker can disrupt the normal operation of the device by sending malicious commands, potentially causing it to malfunction or stop working.

3. Affected Systems and Software Versions

Affected Systems:

• WHILL Model C2 Electric Wheelchairs
• WHILL Model F Power Chairs

Software Versions:

• The vulnerability affects all software versions that do not enforce authentication for Bluetooth connections. Specific versions are not mentioned in the provided information, but it is crucial to assume that all versions prior to a patch release are vulnerable.

4. Recommended Mitigation Strategies

Immediate Mitigations:

• Disable Bluetooth: Users should disable Bluetooth connectivity when not in use to prevent unauthorized access.
• Physical Security: Ensure that the devices are used in secure environments where unauthorized individuals cannot get within Bluetooth range.
• Monitoring: Implement monitoring solutions to detect and alert on unauthorized Bluetooth pairing attempts.

Long-Term Mitigations:

• Firmware Update: WHILL should release a firmware update that enforces authentication for Bluetooth connections. Users should apply this update as soon as it becomes available.
• Access Controls: Implement strong access controls and encryption for Bluetooth communications to prevent unauthorized access and MitM attacks.
