CVE-2025-49181: Unauthorized API Endpoint Access Leading to Denial of Service and Data Leakage

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

Overview

The disclosed vulnerability, CVE-2025-49181, is a significant security flaw that exposes sensitive system data to unauthorized users due to absence of proper authentication for an API endpoint. This vulnerability has broad implications, affecting any systems and entities that rely on this API for their operations. The exploitation of this vulnerability could lead to Denial of Service (DoS) attacks and data leakage, which is a significant threat to the confidentiality, integrity, and availability of systems and data.

How the Exploit Works

The vulnerability arises from an unsecured API endpoint that does not properly authenticate incoming HTTP requests. As a consequence, an attacker can send HTTP GET requests to the API endpoint and gather sensitive information without authorization. Furthermore, the attacker can send HTTP POST requests to modify the path of the log files and the TCP ports the service runs on, causing disruption of the service and possibly leading to a DoS attack.

Conceptual Example Code

The following is a hypothetical example of how this vulnerability might be exploited. This example demonstrates an unauthorized HTTP POST request that can modify the root path of the log files and the TCP ports:

POST /api/vulnerable_endpoint HTTP/1.1
Host: target.example.com
Content-Type: application/json
{
"new_log_path": "/malicious/path",
"tcp_ports": [80, 443]
}

In this example, the attacker sends a malicious payload that changes the root path of the log files, potentially causing service disruptions or data leakage. Furthermore, the attacker modifies the TCP ports the service runs on, potentially leading to a Denial of Service attack.

Mitigation

To address CVE-2025-49181, it’s recommended to apply the vendor’s patch once it becomes available. In the meantime, the use of a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can provide temporary mitigation, protecting against unauthorized HTTP requests. These systems can detect and block malicious traffic, preventing exploitation of this vulnerability.
