WeGIA Web Manager | Before Version 3.5.0

How the Exploit Works

The vulnerability resides in the control.php endpoint of WeGIA’s web manager, specifically on the id_produto parameter. It is open to SQL Injection attacks, allowing an attacker to insert malicious SQL code in the ‘id_produto’ parameter that could manipulate the application’s SQL queries. The successful exploitation of this vulnerability could lead to unauthorized access, manipulation of data, or even system compromise.

Conceptual Example Code

Here is a conceptual example of how an SQL Injection attack might be executed using this vulnerability:

POST /control.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
nomeClasse=ProdutoControle&metodo=excluir&id_produto=1; DROP TABLE users

In this example, the attacker injects a malicious SQL command (`DROP TABLE users`) that could potentially delete a table from the database, causing significant data loss.

Mitigation Guidance

To mitigate this vulnerability, users are advised to immediately apply the vendor patch and update the WeGIA web manager to version 3.5.0 or later, as it has been patched in this version. In case application of the vendor patch is not immediately feasible, using a Web Application Firewall (WAF) or Intrusion Detection System (IDS) is recommended as a temporary mitigation method. It is also important to validate, sanitize, and use prepared statements for all input data to prevent SQL Injection vulnerabilities in general.
