How the Exploit Works
The vulnerability CVE-2025-52327, is a SQL Injection vulnerability that exists in the payment.php file of the Restaurant Order System 1.0. An attacker, with local access, can send specially crafted SQL queries through this file. As a result of the system’s improper input validation, these malicious SQL queries will be executed directly on the database. This can lead to unauthorized access to sensitive data, potential system compromise, and data leakage.
Conceptual Example Code
Here is a simplified example of how an attacker might exploit this vulnerability:
POST /payment.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
credit_card=1234567890123456'; DROP TABLE Orders;--In this example, the attacker attempts to pay with a credit card number that includes a SQL injection attack (`’; DROP TABLE Orders;–`). If the system does not correctly sanitize this input, it might execute the `DROP TABLE Orders;` SQL command, deleting the entire Orders table from the database.
Recommendations for Mitigation
The best way to mitigate this vulnerability is to apply the patch provided by the vendor. If this is not immediately possible, using a Web Application Firewall (WAF) or an Intrusion Detection System (IDS) can serve as temporary mitigation. These systems can detect and block SQL injection attacks, protecting the system until the patch can be applied.
Additionally, it is highly recommended to follow secure coding practices, such as validating and sanitizing all user inputs, which can prevent many types of injection vulnerabilities, including SQL injection.
