Code-Projects Computer Book Store SQL Injection Vulnerability in admin_delete.php

A SQL injection vulnerability exists in version 1.0 of the Code-Projects Computer Book Store application. The issue arises in the admin_delete.php file, where the bookisbn parameter is manipulated to inject malicious SQL code. This unsanitized input is used in SQL queries, allowing attackers to access the database, modify or delete data, and extract sensitive information. The vulnerability can be exploited remotely without authentication.

Impact

Exploitation of this vulnerability allows for unauthorized database access, data modification or deletion, and extraction of sensitive information. Such actions could lead to a complete compromise of the system.

Reproduction

The vulnerability can be reproduced by sending a GET request to the admin_delete.php file with a crafted bookisbn parameter that includes SQL injection payloads. This can be done using tools like sqlmap, which can automate the exploitation of SQL injection vulnerabilities.

Remediation

To address this vulnerability, 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 conforms to expected formats. Finally, database user permissions should be minimized to reduce the impact of potential exploitation.
