How the Exploit Works

The vulnerability allows an attacker to inject malicious SQL queries into the FunnelKit Funnel Builder. The application fails to properly sanitize user-supplied inputs, allowing for the execution of arbitrary SQL commands. An attacker can leverage this to manipulate the application’s database, potentially leading to unauthorized access, data modification, or even system compromise.

Conceptual Example Code

This is a conceptual example demonstrating how an attacker might exploit the vulnerability. The attacker injects malicious SQL code through the vulnerable application:

POST /funnelkit/updateProfile HTTP/1.1
Host: target.example.com
Content-Type: application/json
{ "username": "admin'; DROP TABLE users;--" }

In this example, the attacker attempts to delete the “users” table from the database. If successful, this could lead to significant data loss and disruption of the application’s functionality.
For mitigation, users are advised to apply the latest vendor patches immediately. If this is not possible, employing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure.
