PHPGurukul Online Shopping Portal SQL Injection Vulnerability in Order Details Component

A SQL injection vulnerability exists in PHPGurukul Online Shopping Portal Project version 2.1, specifically within the '/order-details.php' file. The issue arises in the Parameter Handler component, where the 'orderid' parameter can be manipulated to inject malicious SQL code. This unsanitized input is directly used in SQL queries, allowing attackers to alter the queries and execute unauthorized database operations. The vulnerability can be exploited remotely.

Impact

Exploitation of this vulnerability allows attackers to inject malicious SQL queries, potentially leading to unauthorized database access, data manipulation or deletion, and exposure of sensitive information.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/shopping/order-details.php' with the 'orderid' parameter. The injection can be verified using payloads that exploit boolean-based blind or time-based blind SQL injection techniques.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure that user input meets expected formats, thereby blocking malicious data. Finally, database user permissions should be minimized, ensuring that the account used for database connections has only the necessary privileges.
