itsourcecode Online Pet Shop Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in the itsourcecode Online Pet Shop Management System version 1.0. The issue arises in the file '/pet1/update_cnp.php', where insufficient input validation of the 'id' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

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

Reproduction

The vulnerability can be reproduced by sending a POST request to '/pet1/update_cnp.php' with an 'id' parameter that includes a crafted SQL payload. This payload should exploit the application's SQL query handling, taking advantage of the lack of proper input sanitization.

Remediation

To address this vulnerability, it is recommended to implement input validation and sanitization for the 'id' parameter, ensuring that only expected values are accepted. Additionally, using prepared statements for database queries can help prevent SQL injection by separating SQL code from user input.
