SourceCodester Train Station Ticketing System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in SourceCodester Train Station Ticketing System version 1.0. The issue resides in the file '/ajax.php?action=save_station', where insufficient input validation of the 'id/station' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, 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 result in 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 '/ajax.php?action=save_station' with crafted payloads in the 'id' or 'station' parameters that exploit 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 use prepared statements and parameter binding to prevent SQL injection, validate and filter user input, minimize database user permissions, and conduct regular security audits.
