Overview
CVE-2025-6666 is a low-severity vulnerability affecting motogadget mo.lock Ignition Lock up to version 20251125. The vulnerability resides in the NFC handler component and can be exploited through manipulation to potentially utilize a hard-coded cryptographic key. This could allow an attacker with physical access to the device to bypass security measures.
Technical Details
The vulnerability lies within the NFC handler functionality of the motogadget mo.lock. An attacker with physical proximity to the device could potentially manipulate NFC communication to trigger the use of a hard-coded cryptographic key. The exact mechanism for exploiting this vulnerability is not publicly detailed, but it appears to involve exploiting weaknesses in how the mo.lock authenticates NFC-based unlock requests. The attack complexity is considered high, suggesting specific timing, signal manipulation, or pre-requisite knowledge is necessary for successful exploitation.
The vendor was contacted regarding this vulnerability but has not responded.
CVSS Analysis
- Severity: Low
- CVSS Score: 2.0
The CVSS score of 2.0 reflects the low severity of this vulnerability. The exploit requires physical access, involves a high level of complexity, and the vendor has not provided any remediation. The potential impact is limited to bypassing the intended NFC unlock mechanism.
Possible Impact
Successful exploitation of CVE-2025-6666 could allow an attacker with physical access to the motogadget mo.lock to bypass the intended NFC-based authentication and potentially gain unauthorized access or control. While the CVSS score is low, the impact could be significant for individuals relying on the mo.lock for security.
Mitigation or Patch Steps
Currently, there are no official mitigation or patch steps available from motogadget, as the vendor has not responded to the disclosure. Until a patch is released, users are advised to:
- Be vigilant about physical access to their mo.lock device.
- Consider alternative security measures to supplement the NFC unlock functionality.
- Monitor the vendor’s website for any potential updates or advisories.
