CVE-2025-6526 Overview
CVE-2025-6526 affects the 70mai M300 dashcam firmware up to build 20250611. The vulnerability resides in the device's HTTP server and exposes insufficiently protected credentials to attackers on the same local network. The weakness maps to CWE-522: Insufficiently Protected Credentials. An attacker who reaches the dashcam's Wi-Fi or local segment can retrieve the embedded root password without authentication. The vendor was contacted before public disclosure but did not respond. A public write-up detailing the finding is available on GitHub.
Critical Impact
Unauthenticated adjacent-network attackers can recover the device root password from the HTTP server, enabling full administrative access to the dashcam.
Affected Products
- 70mai M300 dashcam hardware
- 70mai M300 firmware versions up to and including 20250611
- Deployments relying on the device's built-in Wi-Fi HTTP service
Discovery Timeline
- 2025-06-23 - CVE-2025-6526 published to the National Vulnerability Database
- 2026-06-17 - Last updated in NVD database
Technical Details for CVE-2025-6526
Vulnerability Analysis
The 70mai M300 exposes an HTTP server over its local Wi-Fi interface for configuration and media access. The server returns sensitive credential material, including the device root password, without requiring authentication. An attacker associated with the dashcam's wireless network can request the affected endpoint and parse the response for the credential string.
The vulnerability is categorized as information disclosure of hardcoded credentials. Because the exposed secret is the root password, successful retrieval grants administrative control over the embedded Linux system. The attack is constrained to the adjacent network, which raises exploitation complexity but does not require user interaction or prior privileges.
Root Cause
The root cause is a design flaw in the HTTP server implementation that returns credential data in an unauthenticated response. The firmware does not segregate sensitive configuration material from endpoints reachable without a session token. The embedded root password is also static across devices on the affected firmware line, which amplifies impact once the credential is extracted.
Attack Vector
Exploitation requires network adjacency to the dashcam. An attacker associates with the device's Wi-Fi access point or shares a local segment, then queries the unauthenticated HTTP endpoint documented in the public write-up. The attacker extracts the root password from the response and reuses it to authenticate to any remaining administrative interfaces, such as Telnet, SSH, or shell services exposed by the firmware. See the public finding write-up on GitHub for the specific endpoint and response format.
No verified code example is published alongside the disclosure. Readers should consult the referenced write-up for the exact request path.
Detection Methods for CVE-2025-6526
Indicators of Compromise
- Unexpected associations to the 70mai M300 Wi-Fi SSID from unknown MAC addresses
- HTTP GET requests to the dashcam's management endpoints originating from devices other than the paired mobile application
- Telnet or SSH sessions to the dashcam using the root account from unauthorized hosts
- New or modified files on the dashcam storage that were not written by the paired user
Detection Strategies
- Monitor wireless traffic to the dashcam's SSID using packet capture to identify unauthenticated HTTP requests from unknown clients
- Correlate device logs with mobile application activity to flag HTTP sessions that do not originate from paired devices
- Use network segmentation telemetry to alert when the dashcam appears on segments outside its intended isolated SSID
Monitoring Recommendations
- Review the vendor references on VulDB entry 313643 for updated indicators and firmware status
- Capture periodic configuration snapshots of the dashcam to detect credential or service changes
- Alert on any administrative service exposure (Telnet, SSH, HTTP) when the device is operated outside a controlled environment
How to Mitigate CVE-2025-6526
Immediate Actions Required
- Do not connect the 70mai M300 Wi-Fi to shared or public networks; keep it isolated to the paired mobile device
- Disable the dashcam Wi-Fi when the mobile application is not actively in use
- Treat the dashcam as untrusted and avoid storing sensitive media that could be retrieved via the exposed credentials
- Track vendor communications for a firmware update that removes the unauthenticated credential endpoint
Patch Information
As of the last NVD modification on 2026-06-17, 70mai has not published a public advisory or confirmed patch for CVE-2025-6526. The disclosure record on VulDB CTI 313643 notes that the vendor did not respond to coordinated disclosure attempts. Monitor the vendor's official support channels for firmware builds that supersede 20250611 and verify the HTTP endpoint no longer returns credential material before redeploying.
Workarounds
- Operate the dashcam only within a trusted, isolated wireless environment with no additional clients
- Change the default Wi-Fi SSID and WPA2 passphrase to reduce opportunistic association by nearby attackers
- Power off or physically disconnect the dashcam when parked in locations where adjacent-network attackers could reach the Wi-Fi
- If the firmware permits, disable the embedded HTTP server when not required for configuration
