CVE-2025-7076 is a vulnerability identified in the BlackVue Dashcam 590X device, specifically affecting versions up to 20250624. The flaw resides in the /upload.cgi endpoint of the Configuration Handler component, where improper access controls allow unauthorized manipulation. This vulnerability enables an attacker within the local network to bypass intended access restrictions, potentially altering configuration settings or uploading malicious content to the device. The attack vector requires local network access, meaning the attacker must be connected to the same network as the dashcam, which limits remote exploitation but still poses a significant risk in environments where network segmentation is weak or compromised. The vulnerability has been publicly disclosed, and while no known exploits are currently reported in the wild, the availability of exploit details increases the likelihood of future attacks. The vendor, BlackVue, has not responded to the disclosure, and no patches or mitigations have been officially released. The CVSS 4.0 base score is 5.3, indicating a medium severity level, primarily due to the requirement for local network access and the absence of user interaction or privileges needed for exploitation. The impact on confidentiality and availability is limited but present, as unauthorized access to configuration could lead to data exposure or denial of service through device misconfiguration.

For European organizations, the impact of this vulnerability depends on the deployment context of BlackVue Dashcam 590X devices. These dashcams are commonly used in commercial fleets, logistics, law enforcement, and private vehicles. Unauthorized access to device configurations could allow attackers to disable recording, manipulate stored footage, or interfere with device operation, undermining security monitoring and evidence collection. In sectors such as transportation, public safety, and insurance, this could result in loss of critical data integrity and availability, affecting incident investigations and operational safety. Additionally, if the dashcams are connected to broader corporate networks without proper segmentation, attackers could leverage this foothold to pivot to other internal systems. The local network access requirement reduces the risk from remote attackers but does not eliminate threats from insider attackers or compromised local devices. The lack of vendor response and patch availability increases exposure duration, raising the risk for organizations that rely on these devices.

European organizations should implement strict network segmentation to isolate dashcam devices from critical IT infrastructure, limiting access to trusted devices only. Employ network access controls such as VLANs and firewall rules to restrict communication with the dashcam's management interfaces. Regularly monitor local network traffic for unusual activity targeting /upload.cgi or other dashcam endpoints. Where possible, disable or restrict access to the /upload.cgi endpoint if it is not required for normal operation. Organizations should also consider deploying endpoint detection and response (EDR) solutions on devices connected to the same network to detect lateral movement attempts. Since no official patch is available, organizations should engage with BlackVue for updates and consider alternative devices if security cannot be assured. Finally, educate staff about the risks of connecting unauthorized devices to corporate networks and enforce strong physical security controls to prevent unauthorized local network access.
