Code-Projects Movie Ticketing System SQL Injection Vulnerability in LogIn.php

A critical SQL injection vulnerability has been identified in version 1.0 of the Code-Projects Movie Ticketing System. The issue resides in the logIn.php file, where the postName parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data modification or deletion, and exposure of sensitive information.

Impact

Exploitation of this vulnerability allows for SQL injection, enabling attackers to manipulate database queries. This could result in unauthorized data access, data leakage, data manipulation, and in some cases, executing administrative operations on the database.

Reproduction

The vulnerability can be reproduced by sending a POST request to the logIn.php file with the postName parameter. Injecting a crafted SQL payload, such as one that exploits time-based blind SQL injection, can demonstrate the vulnerability. The SQL injection can be verified using tools like sqlmap, which can automate the exploitation process.

Remediation

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