Code-Projects Simple Cafe Ordering System SQL Injection Vulnerability in portal.php

A SQL injection vulnerability has been identified in the Simple Cafe Ordering System version 1.0. The issue resides in the portal.php file, where the 'id' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, potentially leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized data access, data leakage, data modification or deletion, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, log into the application and navigate to the portal.php file. The SQL injection can be performed by manipulating the 'id' parameter in the URL. Various payloads can be used to exploit the vulnerability, such as boolean-based blind injection, time-based blind injection, or UNION-based injection.

Remediation

It is recommended to validate and sanitize all user inputs, use parameterized queries or prepared statements to prevent direct injection of user data into SQL queries, implement least privilege principles for database accounts, and apply input length limits to restrict the size of user inputs.
