CVE-2025-6526 is a vulnerability identified in the 70mai M300 dashcam device, specifically affecting versions up to and including 20250611. The flaw resides in the device's HTTP server component, where credentials are insufficiently protected during some unknown processing operation. This weakness could potentially allow an attacker within the same local network to access or manipulate these credentials. However, the attack complexity is rated as high, indicating that exploitation requires significant skill or effort, and no authentication or user interaction is needed for the attack vector. The vulnerability has a low CVSS 4.0 base score of 2.3, reflecting limited impact and difficulty of exploitation. The vendor has not responded to early notifications about this issue, and no patches or mitigations have been publicly released. The exploit details have been disclosed publicly, but no known active exploitation in the wild has been reported. The vulnerability primarily impacts confidentiality due to the exposure of credentials, but does not affect integrity or availability of the device or network services. The attack surface is limited to local network access, meaning remote exploitation over the internet is not feasible without prior network access or compromise.

For European organizations, the direct impact of this vulnerability is relatively low due to the requirement for local network access and the high complexity of exploitation. However, organizations using 70mai M300 devices in their fleet vehicles or security monitoring setups could face credential exposure risks if an attacker gains local network access, potentially leading to unauthorized access to device management interfaces or data streams. This could undermine the confidentiality of recorded footage or device configurations. While the vulnerability does not directly compromise device integrity or availability, credential leakage could facilitate further lateral movement or reconnaissance within a local network. Given the low severity and limited attack scope, the overall risk to large enterprises is minimal unless the devices are deployed in sensitive environments with weak network segmentation. Small and medium businesses or individual users with less mature network security controls may be more vulnerable to local attacks exploiting this flaw.

Since no official patches or updates have been released by the vendor, European organizations should implement compensating controls to mitigate risk. These include: 1) Strict network segmentation to isolate 70mai M300 devices on dedicated VLANs or subnets, preventing unauthorized local network access. 2) Enforce strong access controls and monitoring on local networks, including MAC address filtering and network access control (NAC) solutions to limit device connectivity. 3) Disable or restrict HTTP server access on the devices if possible, or change default credentials to strong, unique passwords. 4) Employ network intrusion detection systems (NIDS) to monitor for unusual traffic patterns targeting the devices. 5) Educate users and administrators about the risk of local network attacks and encourage physical security to prevent unauthorized network access. 6) Regularly audit device firmware versions and configurations to identify vulnerable devices and plan for replacement or vendor engagement. 7) Consider deploying endpoint detection and response (EDR) solutions on connected management systems to detect lateral movement attempts. These targeted measures go beyond generic advice by focusing on network-level containment and access control tailored to the device's attack vector and environment.
