CVE-2025-6525: 70mai 1S Authorization Bypass Vulnerability

CVE-2025-6525 Overview

CVE-2025-6525 is an improper authorization vulnerability [CWE-266] in the 70mai 1S dashcam firmware up to version 20250611. The flaw resides in the Configuration Handler component, specifically the /cgi-bin/Config.cgi?action=set endpoint. An attacker on the same local network can manipulate configuration parameters without proper authorization checks. The vendor was contacted before public disclosure but did not respond. The exploit details have been published, increasing the risk of opportunistic abuse against exposed devices.

Critical Impact
An adjacent-network attacker can modify device configuration without authorization, affecting integrity of the 70mai 1S dashcam settings.

Affected Products

70mai 1S dashcam firmware versions up to and including 20250611
Configuration Handler component exposing /cgi-bin/Config.cgi
Devices reachable over the local or Wi-Fi network used by the dashcam

Technical Details for CVE-2025-6525

Vulnerability Analysis

The vulnerability affects the configuration-setting path of the 70mai 1S dashcam web interface. The /cgi-bin/Config.cgi?action=set endpoint accepts configuration changes but does not enforce authorization on the requester. Any client that can reach the device over the local network can submit a set request and modify device parameters. Because the attack vector is adjacent network, exploitation requires network-layer access such as association with the dashcam Wi-Fi or presence on the same local segment. The flaw is tracked under [CWE-266: Incorrect Privilege Assignment].

Root Cause

The root cause is missing authorization enforcement in the Configuration Handler. The CGI endpoint processes action=set requests without validating that the caller holds administrative privileges. Authentication and authorization layers that should gate configuration changes are either absent or bypassable through direct requests to the CGI script.

Attack Vector

An attacker joins the same network as the dashcam, then issues an HTTP request to /cgi-bin/Config.cgi with action=set and attacker-chosen parameters. The device accepts the request and applies the configuration change. Technical write-up details are published in the GitHub Unauthorized Config Change Guide and summarized in the VulDB entry #313642.

No verified exploit code is reproduced here. See the referenced write-up for request details.

Detection Methods for CVE-2025-6525

Indicators of Compromise

HTTP requests to /cgi-bin/Config.cgi containing action=set originating from clients that are not the owner's mobile application
Unexpected changes to dashcam configuration such as Wi-Fi credentials, recording settings, or administrative parameters
Repeated probing of /cgi-bin/ paths from devices on the local Wi-Fi segment

Detection Strategies

Capture traffic between client devices and the dashcam to identify unauthorized Config.cgi requests
Baseline the mobile companion application's expected request patterns and alert on deviations
Review device configuration state on a schedule and flag unexpected changes

Monitoring Recommendations

Monitor the wireless segment that hosts the dashcam for new or unknown client associations
Log DHCP and ARP activity on networks where the device operates to detect rogue clients
Track firmware version strings reported by the device to confirm patch status when an update becomes available

How to Mitigate CVE-2025-6525

Immediate Actions Required

Isolate the 70mai 1S on a dedicated network segment or guest Wi-Fi with no other trusted clients
Disable the dashcam Wi-Fi when not actively pairing with the owner's mobile application
Restrict physical and wireless proximity access to the vehicle and device

Patch Information

No vendor patch is available at the time of publication. The vendor was contacted prior to disclosure but did not respond, according to the published advisory. Monitor the VulDB record #313642 and the vendor's support channels for firmware updates addressing the Configuration Handler authorization logic.

Workarounds

Keep the dashcam Wi-Fi powered off except during intentional configuration sessions
Change default credentials and the device SSID to limit opportunistic discovery
Avoid connecting the dashcam to shared or untrusted wireless networks
Periodically audit device settings and reset the device if unauthorized changes are detected

bash

# Example: disable the dashcam Wi-Fi radio from the owner's companion application
# or power-cycle the device after each configuration session to minimize exposure
