How the Exploit Works

The vulnerability lies in the endpoint `/WeGIA/html/socio/sistema/processa_deletar_socio.php`, specifically within the `id_socio` parameter. This flaw allows the execution of arbitrary SQL commands, thus enabling an attacker to manipulate the database, compromise the confidentiality, integrity, and availability of stored data. This type of attack, known as SQL Injection, is one of the oldest and most potent web application vulnerabilities, allowing an attacker to interact directly with the website’s database.

Conceptual Example Code

Here’s a conceptual example of how an attacker might exploit this vulnerability using a malicious SQL command:

POST /WeGIA/html/socio/sistema/processa_deletar_socio.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
id_socio=1; DROP TABLE users;

In this example, the string `1; DROP TABLE users;` is injected into the `id_socio` parameter. If the parameter is not properly sanitized, the SQL interpreter will execute two SQL commands: the first one is the intended operation (with id_socio = 1), and the second one (DROP TABLE users) is the injected malicious operation which will delete the users table from the database.

Mitigation

The immediate mitigation for this vulnerability is to apply the vendor-provided patch, upgrading to WeGIA version 3.4.5. If, for any reason, immediate patching is not possible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can provide temporary mitigation. They should be configured to detect and block suspicious and malicious SQL commands.
Nevertheless, the best long-term strategy would be to adopt secure coding practices that prevent SQL injection vulnerabilities, such as using parameterized queries or prepared statements, and always validating and sanitizing user input.
