WeGIA | Prior to 3.4.8

How the Exploit Works

The vulnerability exists due to an improper authentication check in the WeGIA web manager’s endpoint /html/personalizacao_remover.php. This allows an anonymous attacker to delete any image files by defining imagem_0 as the image id to delete.

Conceptual Example Code

Given the nature of the vulnerability, an attacker could exploit it using a simple HTTP DELETE request. Here is a conceptual example of how the vulnerability might be exploited:

DELETE /html/personalizacao_remover.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
imagem_0={Image_id_to_delete}

In this example, {Image_id_to_delete} would be the identifier of the image that the attacker wishes to delete.

Mitigation Guidance

To mitigate this vulnerability, users are advised to apply the patch provided by the vendor in version 3.4.8. As a temporary mitigation, users could also employ a Web Application Firewall (WAF) or Intrusion Detection System (IDS) to monitor and block malicious requests.
