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/contact-us.php' file, where the 'pagetitle' parameter is manipulated, leading to unauthorized database access. This vulnerability allows attackers to inject malicious SQL queries, potentially modifying or deleting data and accessing sensitive information. The flaw arises from inadequate input validation, enabling exploitation without authentication.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can 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 the '/banker/contact-us.php' page with the 'pagetitle' 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 use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance the application's security.
