CVE-2025-41661: Unauthenticated Remote Command Execution Vulnerability due to CSRF in Main Web Interface

Ameeba’s Mission: Safeguarding privacy by securing data and communication with our patented anonymization technology.

Overview

The cybersecurity landscape is continually evolving, with new vulnerabilities being discovered and exploited. One such vulnerability that has recently come to light is CVE-2025-41661. This vulnerability allows an unauthenticated remote attacker to execute arbitrary commands with root privileges on affected devices. It is due to the lack of Cross-Site Request Forgery (CSRF) protection in the Main Web Interface, specifically at the endpoint event_mail_test. This vulnerability is particularly concerning because it can lead to total system compromise or data leakage, posing severe risks.

How the Exploit Works

The exploit works by leveraging the lack of CSRF protections in the main web interface. When an attacker sends a malicious request to the event_mail_test endpoint, the vulnerable system processes this request as legitimate. Since this endpoint lacks CSRF protection, there’s no mechanism to verify whether the incoming request was intentionally made by an authenticated user. As a result, an attacker can force the endpoint to execute arbitrary commands with root privileges, leading to system compromise or data leakage.

Conceptual Example Code

Here’s a conceptual example of how the vulnerability might be exploited:

POST /event_mail_test HTTP/1.1
Host: vulnerable.example.com
Content-Type: application/json
{ "command": "rm -rf /; echo 'System Compromised'" }

In this example, the malicious payload is a command that deletes all files on the system and prints ‘System Compromised’. It’s important to note this is a conceptual representation, and actual exploits may vary based on the system’s configuration and the attacker’s intention.
To mitigate this vulnerability, it is recommended to apply the vendor patch as soon as it becomes available. In the meantime, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation by detecting and blocking suspicious activity.
