PHPGurukul Bank Locker Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in PHPGurukul Bank Locker Management System version 1.0. The issue resides in the '/banker/add-lockertype.php' file, where the 'lockerprice' parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, allowing attackers to gain unauthorized access to the database, modify or delete data, and access sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could lead to 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 '/banker/add-lockertype.php' with the 'lockerprice' parameter. The request should include a crafted SQL payload that exploits the application's SQL query handling. This can be done using tools like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities.

Remediation

To address this vulnerability, it is recommended to implement input validation and sanitization for the 'lockerprice' parameter. Additionally, using prepared statements for database queries can help prevent SQL injection by separating SQL code from user input.
