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 file '/banker/edit-assign-locker.php?ltid=1', where the 'mobilenumber' parameter is manipulated, leading to unauthorized database access. This vulnerability can be exploited remotely, without any authentication, allowing attackers to inject malicious SQL queries that could be used to access, modify, or delete sensitive data.

Impact

Exploitation of this vulnerability allows for SQL injection, where attackers can inject malicious SQL queries into the database. This could lead to unauthorized data access, data manipulation, and in some cases, executing administrative operations on the database.

Reproduction

To reproduce this vulnerability, send a POST request to '/banker/edit-assign-locker.php?ltid=1' with the 'mobilenumber' parameter. Include a payload that exploits the SQL injection vulnerability, such as a time-based blind SQL injection payload that uses the 'SLEEP' function to demonstrate the injection.

Remediation

It is recommended to use prepared statements and parameter binding to prevent SQL injection vulnerabilities. Additionally, input validation and filtering should be implemented to ensure that user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help mitigate such vulnerabilities.
