PHPGurukul Dairy Farm Shop Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Dairy Farm Shop Management System version 1.3. The issue arises in the file '/bwdate-report-details.php', where the 'fromdate' and 'todate' parameters are not properly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without the need for authentication.

Impact

Exploitation of this vulnerability allows unauthorized access to the application's database, where attackers can leak, modify, or delete data. Additionally, it could lead to complete control over the system and disruption of services.

Reproduction

The vulnerability can be reproduced by sending a POST request to '/bwdate-report-details.php' with a crafted 'fromdate' parameter that includes malicious SQL code. This injected SQL is executed by the database, allowing the attacker to manipulate database queries and access or modify sensitive information.

Remediation

To address this vulnerability, developers should implement prepared statements and parameter binding to separate SQL code from user input. Additionally, input validation and filtering should be applied to ensure that data conforms to expected formats, blocking malicious input. It is also recommended to minimize database user permissions, granting only the necessary rights for operations and avoiding high-privilege accounts.
