CVE-2025-6527 is a vulnerability identified in the 70mai M300 dashcam device, specifically affecting an unspecified function within its embedded web server component. The flaw results in improper access controls, potentially allowing unauthorized actions or information disclosure within the local network environment. The vulnerability is classified as problematic but with a low severity score of 2.3 under CVSS 4.0, reflecting limited impact and exploitability. The attack vector is local network access only (AV:A), requiring high attack complexity (AC:H), and no privileges, user interaction, or authentication are needed to exploit it. The vulnerability does not affect confidentiality, integrity, or availability significantly (VC:L, VI:N, VA:N). The exploitability is considered difficult, and no known exploits have been observed in the wild. The vendor, 70mai, was contacted early but has not responded or issued a patch. The vulnerability disclosure date is June 23, 2025. Given the nature of the device—a consumer-grade dashcam with a web server interface—the risk is primarily limited to attackers with local network access, such as those connected to the same Wi-Fi network. The improper access controls could allow an attacker to manipulate device settings or access limited device data, but the overall impact is constrained by the device's functionality and network scope. The lack of vendor response and patch availability increases the importance of mitigating exposure through network controls and device management.

For European organizations, the direct impact of CVE-2025-6527 is relatively low due to the limited scope and low severity of the vulnerability. However, organizations that deploy 70mai M300 dashcams in fleet vehicles or corporate environments could face localized risks if attackers gain access to the internal network segment where these devices operate. Potential impacts include unauthorized configuration changes or limited data exposure from the dashcam, which could affect operational monitoring or vehicle security. While the vulnerability does not directly compromise core IT systems, it could serve as a foothold for lateral movement within segmented networks if combined with other vulnerabilities or weak network segmentation. The lack of vendor patching means organizations must rely on compensating controls. Given the high attack complexity and local network requirement, the threat is less critical for organizations with strong network segmentation and access controls. However, organizations with less mature network security or extensive use of these devices in sensitive environments should consider the risk more seriously.

1. Network Segmentation: Isolate 70mai M300 devices on dedicated VLANs or network segments with strict access controls to prevent unauthorized local network access. 2. Access Control Enforcement: Restrict access to the dashcam’s web server interface to trusted administrators only, using MAC filtering or IP whitelisting where possible. 3. Disable Unnecessary Services: If feasible, disable the web server or remote management features on the device to reduce the attack surface. 4. Monitor Network Traffic: Implement network monitoring to detect unusual access patterns or attempts to connect to the dashcam’s web interface. 5. Physical Security: Ensure devices are physically secured to prevent attackers from connecting directly to the local network or device interfaces. 6. Vendor Engagement: Continue to monitor for vendor updates or patches, and consider alternative devices if the vendor remains unresponsive. 7. Incident Response Preparedness: Develop procedures to quickly isolate affected devices if suspicious activity is detected. These steps go beyond generic advice by focusing on network architecture and operational controls tailored to the device’s deployment context.
