Overview
The cybersecurity landscape is constantly evolving with new vulnerabilities surfacing regularly. In this blog post, we will be discussing a critical vulnerability identified as CVE-2025-24522. This vulnerability affects the KUNBUS Revolution Pi OS Bookworm version 01/2025. This is a significant vulnerability because of the absence of default authentication for the Node-RED server, which could potentially give an unauthenticated remote attacker full command execution privileges on the underlying operating system. Given the potential impact, the vulnerability raises serious security implications for any organization using the affected software, and it is essential to understand the risk it poses and how to mitigate it.

KUNBUS Revolution Pi OS Bookworm | 01/2025
How the Exploit Works
The CVE-2025-24522 vulnerability arises due to inadequate security configurations in the KUNBUS Revolution Pi OS Bookworm version 01/2025. By default, authentication is not configured for the Node-RED server. This opens a window of opportunity for an unauthenticated remote attacker to gain full access to the Node-RED server. Once the attacker has gained access to the server, they can run arbitrary commands on the underlying operating system, leading to system compromise and potential data leakage.
Conceptual Example Code
Here is a conceptual code snippet showing how an attacker might exploit this vulnerability:
POST /node-red/execute HTTP/1.1
Host: target.example.com
{
"command": "rm -rf /*"
}
In this conceptual example, an unauthenticated attacker sends an HTTP POST request to the Node-RED server’s execute endpoint. The malicious payload, here represented by a destructive `rm -rf /*` command, gets executed on the server’s underlying operating system.
Recommended Mitigation
The best way to mitigate this vulnerability is by applying the vendor patch as soon as it becomes available. Alternatively, a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can be used as temporary mitigation. These solutions can identify and prevent malicious traffic or activities, thereby reducing the risk of successful exploitation. Furthermore, it is advisable to always ensure proper security configurations, such as enabling authentication on all servers, to reduce the attack surface.
To conclude, vulnerabilities like CVE-2025-24522 highlight the importance of robust security configurations and timely patch management in cybersecurity. It is crucial to stay informed about such vulnerabilities and to take prompt action to mitigate them.
