Overview
The CVE-2025-58159 vulnerability refers to a serious remote code execution flaw found in WeGIA, a widely-used Web manager for charitable institutions. This vulnerability, if exploited, could potentially allow an attacker to compromise the system or leak sensitive data. It impacts versions of WeGIA prior to 3.4.11 and is of significant concern due to the high CVSS severity score of 9.9. Its discovery underlines the necessity of regular system updates and robust cybersecurity measures within the nonprofit sector.

WeGIA Web Manager | Prior to version 3.4.11
How the Exploit Works
The vulnerability stems from WeGIA Web Manager’s improper validation of uploaded files. More specifically, the application permits an attacker to upload files with arbitrary filenames, including those with a .php extension. As the uploaded file is written directly to disk without sufficient sanitization or extension restrictions, an attacker can upload a spreadsheet file containing PHP code. This code can then be executed on the server, allowing the attacker to run arbitrary code and potentially compromise the system.
Conceptual Example Code
This is a conceptual example of how the vulnerability might be exploited. An attacker might craft a request like this:
POST /upload/file HTTP/1.1
Host: vulnerable-charity.org
Content-Type: multipart/form-data; boundary=----WebKitFormBoundary7MA4YWxkTrZu0gW
------WebKitFormBoundary7MA4YWxkTrZu0gW
Content-Disposition: form-data; name="file"; filename="exploit.php"
Content-Type: application/php
<?php
// Malicious PHP code here
?>
------WebKitFormBoundary7MA4YWxkTrZu0gW--In the example above, the attacker sends a POST request to the /upload/file endpoint with a malicious PHP file. If the server is vulnerable, it will accept and save the file, allowing the attacker to execute their code on the server.
Recommendations
To mitigate this vulnerability, users are strongly advised to apply the vendor’s patch by updating their WeGIA Web Manager to version 3.4.11 or later. If unable to do so immediately, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could serve as a temporary mitigation measure. As always, it is recommended to follow good cybersecurity practices, such as regularly updating software and monitoring system activity for any unusual behavior.
