PHPGurukul Zoo Management System SQL Injection Vulnerability in Manage Animals Admin Page

A critical SQL injection vulnerability has been identified in PHPGurukul Zoo Management System version 2.1. The issue resides in the admin manage-animals.php file, where the ID parameter is manipulated to inject malicious SQL code. This vulnerability can be exploited remotely, allowing attackers to interfere with SQL queries and execute unauthorized database operations.

Impact

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

Reproduction

The vulnerability can be reproduced by sending a GET request to the /admin/manage-animals.php page with a crafted id parameter that includes SQL injection payloads. The injection takes place because the application does not properly sanitize or validate the input before using it in SQL queries. This can be done manually or with automated tools like sqlmap, which can exploit the vulnerability and extract database information.

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, blocking malicious data. Finally, database user permissions should be minimized, granting only necessary access rights to the database.
