Overview
The cybersecurity realm is no stranger to the term “SQL Injection,” a notorious vulnerability that has been the bane of web applications for years. In this context, we will be discussing a new vulnerability, CVE-2025-55167, discovered in WeGIA, an open-source web manager primarily used by Portuguese language users and charitable institutions. This vulnerability is particularly important due to the potential devastating impacts it can have on the confidentiality, integrity, and availability of a system’s database.

WeGIA | Prior to 3.4.8
How the Exploit Works
The vulnerability lies in the /html/funcionario/dependente_remover.php endpoint, specifically in the id_dependente parameter. An attacker can exploit this by injecting malicious SQL commands into this parameter. These commands are then executed by the database, giving the attacker the ability to manipulate the data as per their wish, thereby compromising the confidentiality, integrity, and availability of the system’s database.
Conceptual Example Code
Here is a conceptual example of how an attacker might exploit this vulnerability:
POST /html/funcionario/dependente_remover.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
id_dependente=1; DROP TABLE users;In the above example, the attacker sends a POST request to the vulnerable endpoint, appending a malicious SQL command (in this case, “DROP TABLE users;”) to the ‘id_dependente’ parameter. If successful, this would delete the ‘users’ table from the database, causing potential data loss and system disruption.
Mitigation
The vulnerability has been patched in WeGIA version 3.4.8. All users are strongly advised to update to this version or later. As a temporary measure, users can use a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) to block or alert on suspicious activity. However, these are not foolproof measures and the recommended action is always to apply the vendor patch as soon as possible.
In the long run, it’s essential to adopt secure coding practices, regular vulnerability scanning, and penetration testing to minimize the risk of such vulnerabilities. Furthermore, input validation and parameterized queries can significantly reduce the risk of SQL injection vulnerabilities.
