PHPGurukul Apartment Visitors Management System SQL Injection Vulnerability in admin-profile.php

A critical SQL injection vulnerability has been identified in version 1.0 of the PHPGurukul Apartment Visitors Management System. The issue arises in the admin-profile.php file, where the mobilenumber parameter is improperly validated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without authentication, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to interfere with the application's 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 admin-profile.php 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

It is recommended to implement input validation and sanitization for the mobilenumber parameter to prevent SQL injection. Additionally, using prepared statements and parameterized queries can help mitigate this vulnerability by separating SQL logic from user input.
