A SQL injection vulnerability has been identified in SourceCodester Computer Repair Shop Management System, specifically in version 1.0. The issue arises in the file '/admin/products/manage_product.php', where the 'id' parameter is not properly validated or sanitized. This flaw allows remote attackers to manipulate the parameter and execute malicious SQL queries, potentially leading to unauthorized data access or modification.

Impact

Exploitation of this vulnerability allows for SQL injection, where an attacker can execute arbitrary SQL commands. This could result in unauthorized data access, data manipulation, or in some cases, executing commands on the server if the database user has sufficient privileges.

Reproduction

The vulnerability can be reproduced by sending a request to the '/admin/products/manage_product.php' endpoint with a crafted 'id' parameter. The SQL injection can be verified using SQL injection tools like sqlmap, which can automate the process of finding and exploiting SQL injection vulnerabilities.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, implement strict input validation and whitelisting for user-supplied data. Regular code security reviews and security testing should also be conducted.
