PHPGurukul Cyber Cafe Management System SQL Injection Vulnerability in adminprofile.php

A critical SQL injection vulnerability has been identified in PHPGurukul Cyber Cafe Management System version 1.0. The issue resides in the adminprofile.php file, where the mobilenumber parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, potentially affecting other parameters as well.

Impact

Exploitation of this vulnerability allows unauthorized access to the database, manipulation or deletion of data, leakage of sensitive information, and could lead to a complete compromise of the system, disrupting normal services.

Reproduction

The vulnerability can be reproduced by sending a POST request to the adminprofile.php file with the mobilenumber 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 prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be applied to ensure that user input meets expected formats, blocking malicious data. Finally, database user permissions should be minimized, granting only the necessary rights to the account used for database connections.
