Projectworlds Online Time Table Generator SQL Injection Vulnerability in add_teacher.php

A critical SQL injection vulnerability has been identified in the Online Time Table Generator PHP MySQL version 1.0, specifically within the admin/add_teacher.php file. The vulnerability arises from inadequate validation of user input in the 'e' parameter, allowing attackers to inject malicious SQL queries that could be executed against the application's database. This SQL injection can be exploited remotely, potentially leading to unauthorized database access, data manipulation, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for unauthorized access to the database, manipulation or deletion of data, and leakage of sensitive information. Such actions could disrupt services and pose a significant risk to overall system security and business operations.

Reproduction

The vulnerability can be reproduced by sending a POST request to the /admin/add_teacher.php endpoint with a crafted 'e' parameter that includes malicious SQL payloads. 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, validate and filter user input, minimize database user permissions, and conduct regular security audits.
