CVE-2025-7070 is a medium-severity vulnerability identified in the IROAD Dashcam Q9 device, specifically affecting versions up to 20250624. The vulnerability resides in an unspecified functionality within the MFA (Multi-Factor Authentication) Pairing Request Handler component. The core issue involves improper allocation of resources triggered by manipulation of this component. While the exact technical mechanism is not fully detailed, the vulnerability allows an attacker within the local network to induce resource allocation conditions that could potentially degrade device performance or lead to denial of service. The attack does not require any authentication or user interaction, making it easier to exploit for an attacker who has local network access. The CVSS 4.0 score is 5.3 (medium), with vector metrics indicating that the attack requires local network access (AV:A), has low attack complexity (AC:L), no privileges or user interaction needed, and results in low impact on availability (VA:L) without affecting confidentiality or integrity. The vendor has been contacted but has not responded or issued a patch, leaving the vulnerability unmitigated at present. No known exploits are reported in the wild, but the lack of vendor response and patch availability increases the risk for affected users. The vulnerability's impact is primarily on availability through resource exhaustion or misallocation, which could disrupt dashcam functionality, potentially affecting evidence recording or driver safety features reliant on the device.

For European organizations, particularly those in transportation, logistics, or fleet management sectors that deploy IROAD Dashcam Q9 devices, this vulnerability poses a risk of service disruption. Dashcams are critical for recording driving events, supporting insurance claims, and ensuring driver accountability. Exploitation could lead to denial of service conditions, causing loss of video recording or interruption of real-time monitoring capabilities. This could result in operational downtime, loss of critical evidence in case of accidents, and potential liability issues. Since the attack requires local network access, organizations with less segmented or poorly secured internal networks are at higher risk. Additionally, organizations relying on these devices for compliance or safety monitoring may face regulatory or operational challenges if the devices become unreliable. The absence of vendor patches means that affected organizations must rely on network-level mitigations and monitoring to reduce risk.

Given the lack of vendor patches, European organizations should implement the following specific mitigations: 1) Network Segmentation: Isolate dashcam devices on dedicated VLANs or subnets with strict access controls to limit local network exposure. 2) Access Control: Restrict network access to dashcams only to authorized management systems and personnel using firewall rules and network access control lists. 3) Monitoring and Detection: Deploy network monitoring tools to detect unusual traffic patterns or repeated pairing requests targeting the MFA Pairing Request Handler, which may indicate exploitation attempts. 4) Device Hardening: Disable any unnecessary network services on the dashcam devices if configurable, and ensure default credentials are changed to strong, unique passwords. 5) Incident Response Preparedness: Develop procedures to quickly isolate or reboot affected devices if signs of resource exhaustion or malfunction appear. 6) Vendor Engagement: Continue to engage with the vendor for patch releases and subscribe to security advisories for updates. 7) Alternative Solutions: Evaluate the feasibility of replacing vulnerable devices with models from vendors with better security track records if risk is unacceptable.
