Overview<\/strong><\/p>\n

The Common Vulnerabilities and Exposures database has recently confirmed the existence of an arbitrary file upload vulnerability in the WeGIA Web manager for charitable institutions. This flaw allows an attacker to upload a webshell to the server for remote code execution, making it a high-risk vulnerability. As WeGIA is commonly used by various charitable institutions to manage their operations, this vulnerability could potentially affect a large number of organizations<\/a>, exposing them to potential system compromise or data leakage.<\/p>\n

Vulnerability Summary<\/strong><\/p>\n

CVE ID: CVE-2025-58745
\nSeverity: Critical 9.9
\nAttack Vector: Network
\nPrivileges Required: Low
\nUser Interaction: None
\nImpact: Potential system compromise and data leakage due to arbitrary file upload and remote code execution<\/a><\/p>\n

Affected Products<\/strong><\/p>\n

Product | Affected Versions<\/p>\n

WeGIA Web Manager<\/a> | Versions earlier than 3.4.11<\/p>\n

How the Exploit Works<\/strong><\/p>\n

The exploit works by taking advantage of the fact that WeGIA only checks MIME types for Excel files at the endpoint<\/a> `\/html\/socio\/sistema\/controller\/controla_xlsx.php`. By using magic bytes of an Excel file in a PHP<\/a> file, an attacker can bypass WeGIA’s MIME type check and upload a webshell to the server. This can lead to remote code execution<\/a>, potentially compromising the entire system or leading to data leakage.<\/p>\n

Conceptual Example Code<\/strong><\/p>\n

Here is a conceptual example of how the vulnerability might be exploited. The attacker sends a POST request with a crafted PHP file<\/a> that contains the magic bytes of an Excel file.<\/p>\n

POST \/html\/socio\/sistema\/controller\/controla_xlsx.php HTTP\/1.1\nHost: target.example.com\nContent-Type: application\/vnd.openxmlformats-officedocument.spreadsheetml.sheet\n{ \"file\": \"\" }<\/code><\/pre>\n
In this example, the uploaded file<\/a> is a PHP script that will execute any command passed to it via the ‘cmd’ GET parameter. This effectively allows the attacker to execute arbitrary<\/a> commands on the server.<\/p>\n
Mitigation<\/strong><\/p>\n
Users of WeGIA Web Manager are strongly advised to update their systems<\/a> to version 3.4.11 or later, which contains a fix for this vulnerability. Until the update can be applied, it’s recommended to use a web application firewall (WAF) or intrusion detection system (IDS) as a temporary mitigation measure.<\/p>\n","protected":false},"excerpt":{"rendered":"
