Overview
In the vast cybersecurity landscape, the discovery of new vulnerabilities is not a surprise. This article focuses on CVE-2025-25271, a critical vulnerability that allows an unauthenticated adjacent attacker to configure a new OCPP backend due to insecure defaults for the configuration interface. This vulnerability affects a wide range of products and services and, if exploited, could lead to system compromise or severe data leakage. Due to the severity and potential impact of this vulnerability, it is crucial for organizations and individuals alike to understand its nature and take the necessary steps to mitigate it.

How the Exploit Works
The exploit takes advantage of insecure defaults for the configuration interface in the OCPP backend. An unauthenticated adjacent attacker can access this interface and, without needing any privileges or user interaction, change the configuration settings. This can result in the attacker gaining control over the system or leaking sensitive data.
Conceptual Example Code
Below is a
conceptual
example that illustrates how this vulnerability might be exploited. This example uses a HTTP POST request to send a malicious payload to the vulnerable endpoint.
POST /config/interface HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "new_backend": "attacker_controlled_server" }In this example, the attacker sends a POST request to the `/config/interface` endpoint. The request contains a JSON object specifying a new backend controlled by the attacker. If the request is successful, the system will start sending data to the attacker’s server, leading to a potential data leak.
In conclusion, CVE-2025-25271 is a critical vulnerability that could lead to serious consequences if left unmitigated. Organizations and individuals are strongly advised to apply the necessary patches from their vendors or implement temporary mitigation measures like a Web Application Firewall (WAF) or Intrusion Detection System (IDS).
