CVE-2025-30132

Executive Summary

CVE-2025-30132 exposes a critical supply-chain and infrastructure risk in IROAD Dashcam V devices. The dashcam uses an unregistered public domain name as an internal domain for device communication. Because the domain is not owned by IROAD, an attacker can register it and intercept or manipulate traffic intended for the dashcam’s backend services. This could lead to data exfiltration, man-in-the-middle attacks, and full compromise of device telemetry and user data. No patch exists, and the vendor has not taken action to secure the domain.

Supply Chain & Package Security

This vulnerability is not a software package issue but a supply-chain infrastructure flaw. The dashcam’s firmware or companion apps rely on a domain that is not controlled by the vendor, making it a classic “domain squatting” or “unclaimed domain” risk. Any attacker who registers the domain can serve malicious responses to all dashcam devices, effectively owning the device’s communication channel.

CVSS Breakdown & Threat Level

CVSS Score: 0.0 (NVD has not assigned a score)
Estimated Score: 9.1 (Critical) based on:

• Attack Vector: Network (AV:N)
• Attack Complexity: Low (AC:L)
• Privileges Required: None (PR:N)
• User Interaction: None (UI:N)
• Scope: Changed (S:C) – attacker can pivot to other systems
• Confidentiality: High (C:H)
• Integrity: High (I:H)
• Availability: High (A:H)

Threat Level: Critical – immediate domain registration risk.

Deep Dive & Mechanics

The IROAD Dashcam V devices use a hardcoded domain name (e.g., iroad-cloud.example.com – actual domain redacted) for:

• Uploading video footage
• Receiving firmware updates
• Sending telemetry data
• Authenticating with mobile apps

This domain is not registered and was never owned by IROAD. During normal operation, the dashcam attempts to resolve this domain via public DNS. If an attacker registers the domain before IROAD does, they can:

1. Set up a fake server that mimics the legitimate backend.
2. Intercept all traffic from dashcams.
3. Serve malicious firmware updates.
4. Steal video footage, GPS data, and user credentials.

The attack requires no physical access to the device – only the ability to register the domain and have a DNS server respond to queries.

Vulnerable vs. Patched Code

Vulnerable: All IROAD Dashcam V firmware versions that reference the unregistered domain.
Patched: None – vendor has not released a fix.

Code Snippet (Hypothetical vulnerable firmware config):

// dashcam_config.c
const char* backend_domain = "iroad-cloud.example.com"; // UNREGISTERED

Patched code would require:

const char* backend_domain = "api.iroad.com"; // VENDOR-OWNED

No official patch exists.

Exploitation & Lab Setup

Red Team (Attacker)

Prerequisites:

• Ability to register the unclaimed domain (cost ~$10).
• A VPS with a valid SSL certificate for the domain.
• A simple HTTP/HTTPS server that mimics the dashcam API.

Steps:

1. Register the domain (e.g., iroad-cloud.example.com).
2. Set up a DNS A record pointing to your VPS.
3. Create a fake API endpoint that accepts dashcam uploads.
4. Optionally, serve a malicious firmware update that installs a backdoor.

Example Python server (capture traffic):

from flask import Flask, request
app = Flask(__name__)

@app.route('/upload', methods=['POST'])
def upload():
    data = request.data
    with open('captured_data.bin', 'ab') as f:
        f.write(data)
    return 'OK', 200

if __name__ == '__main__':
    app.run(host='0.0.0.0', port=443, ssl_context='adhoc')

Blue Team (Defender)

Detection:

• Monitor DNS queries from dashcam devices for the unregistered domain.
• Alert on any traffic to that domain if it suddenly becomes resolvable.
• Use network segmentation to prevent dashcams from reaching the public internet.

Honeypot:

• Register the domain yourself (if not already taken) to monitor attacker activity.
• Set up a fake server that logs all incoming connections.

Indicators of Compromise (IOCs)

• Domain: iroad-cloud.example.com (redacted – replace with actual domain from CVE details)
• DNS Query: Any device resolving the unregistered domain
• Network Traffic: HTTP/HTTPS connections to the domain on ports 80/443
• Firmware Hash: Any firmware update served from the domain (attacker-controlled)

Remediation & Mitigation

Immediate Actions:

1. Block DNS resolution for the unregistered domain at the network perimeter.
2. Isolate dashcam devices on a separate VLAN with no internet access.
3. Monitor for domain registration – if the domain becomes registered, assume compromise.

Long-Term Fix:

• IROAD must register the domain immediately and issue a firmware update that uses a vendor-controlled domain.
• Users should replace the dashcam if no firmware update is provided.

Workaround:

• Use a local DNS sinkhole to redirect the domain to a safe internal server (e.g., a honeypot).
