Compliance Impact

The SQL Injection vulnerability in the Online Food Ordering System 1.0 allows attackers to extract sensitive data such as user credentials, order history, customer personal information, and payment details. This exposure of personal and payment information can lead to non-compliance with data protection regulations like GDPR and HIPAA, which mandate the protection of personal and sensitive data against unauthorized access and breaches.

Additionally, the ability to modify or delete database records, including audit trails, undermines data integrity and accountability requirements often enforced by these standards.

Mitigation Strategies

To mitigate the SQL Injection vulnerability in the Online Food Ordering System 1.0, immediate steps include:

• Apply input validation and sanitization to the 'del' parameter to prevent malicious SQL code injection.
• Use prepared statements or parameterized queries in the /form/cart.php file to safely handle user inputs.
• Restrict or monitor access to the Shopping Cart Module to detect and block suspicious POST requests targeting the 'del' parameter.
• If possible, temporarily disable or restrict the vulnerable functionality until a patch or update is available.
• Monitor logs for unusual delays or suspicious activity indicative of time-based blind SQL injection attempts.

Executive Summary

CVE-2026-4841 is a critical SQL Injection vulnerability found in the Online Food Ordering System 1.0 by code-projects.org. It exists in the Shopping Cart Module within the file /form/cart.php. The vulnerability occurs because the 'del' parameter, which identifies cart items, is directly used in a SQL query without proper sanitization or parameterization.

An attacker can exploit this vulnerability remotely by sending specially crafted POST requests with multipart/form-data encoding. This allows a time-based blind SQL injection attack, where the attacker can confirm the vulnerability by causing delays in the database response.

Impact Analysis

Exploiting this vulnerability can have severe impacts including:

• Extraction of sensitive data such as user credentials, order history, customer personal information, and payment details.
• Modification of database records, including altering prices, manipulating orders, and creating fake orders.
• Deletion of database records, such as removing orders and clearing audit trails.

Overall, a remote attacker can fully compromise the integrity and confidentiality of the Online Food Ordering System's database without needing any privileges or user interaction.

Detection Guidance

This vulnerability can be detected by sending a specially crafted POST request to the vulnerable endpoint and observing the response time for delays caused by SQL injection payloads.

Specifically, the vulnerable parameter is `del` in the `/form/cart.php` file of the Online Food Ordering System 1.0.

A proof-of-concept payload to test for the time-based blind SQL injection is:

• POST /form/cart.php with multipart/form-data encoding and parameter `del` set to: `139' AND (SELECT 5854 FROM (SELECT(SLEEP(10)))hkHH) AND 'pzvo'='pzvo`

If the server response is delayed by approximately 10 seconds, it indicates the presence of the vulnerability.
