CVE-2025-6525 is a medium-severity vulnerability affecting the 70mai 1S dashcam device, specifically versions up to and including 20250611. The vulnerability arises from improper authorization in the Configuration Handler component, located in the /cgi-bin/Config.cgi endpoint with the action parameter set to 'set'. This flaw allows an attacker within the local network to manipulate configuration settings without proper authorization checks. The vulnerability does not require authentication, user interaction, or elevated privileges, and can be exploited remotely but only from within the same local network segment as the device. The CVSS 4.0 vector indicates an attack vector of adjacent network (AV:A), low attack complexity (AC:L), no privileges required (PR:N), no user interaction (UI:N), and limited impact on confidentiality (VC:N), integrity (VI:L), and no impact on availability (VA:N). The vendor has been notified but has not responded or issued a patch, and the exploit details have been publicly disclosed, increasing the risk of exploitation. Although no known exploits are currently observed in the wild, the public availability of exploit information and lack of vendor mitigation elevate the threat level. The vulnerability could allow an attacker to alter device configurations, potentially leading to unauthorized changes in device behavior, data leakage, or disruption of normal operation within the local network environment.

For European organizations, especially those deploying 70mai 1S dashcams in fleet management, logistics, or corporate vehicle environments, this vulnerability poses a risk of unauthorized configuration changes that could compromise device integrity and potentially expose sensitive video or telemetry data. The improper authorization could allow attackers to disable security features, redirect data streams, or alter device settings to facilitate further network reconnaissance or lateral movement. While the attack requires local network access, many corporate networks have segments where such devices are connected, increasing the attack surface. The impact on confidentiality is limited but present due to potential exposure of configuration data or video feeds. Integrity impact is moderate as attackers can modify device settings, potentially undermining trust in recorded evidence or device operation. Availability impact is minimal but could occur if configurations disrupt device functionality. Given the vendor’s lack of response and absence of patches, organizations face prolonged exposure. This vulnerability could also be leveraged in targeted attacks against high-value assets using these devices, especially in sectors like transportation, law enforcement, or critical infrastructure where dashcams are used for monitoring and security.

Organizations should implement network segmentation to isolate 70mai 1S devices from broader corporate networks, restricting access to trusted administrators only. Employ strict access control lists (ACLs) on local network segments to limit which devices can communicate with the dashcams. Monitor network traffic for unusual configuration requests to /cgi-bin/Config.cgi endpoints. Where possible, disable or restrict the CGI interface if not required for normal operation. Use network intrusion detection systems (NIDS) with signatures or behavioral rules to detect exploitation attempts targeting this vulnerability. Since no vendor patch is available, consider deploying compensating controls such as VPN tunnels or secure management VLANs to access the devices remotely, reducing exposure to local network attackers. Regularly audit device configurations and logs for unauthorized changes. Engage with the vendor or consider alternative products with better security track records if the risk is unacceptable. Finally, educate network administrators about the risk and ensure physical security of network segments hosting these devices to prevent unauthorized local access.
