Code-Projects Vehicle Management SQL Injection Vulnerability in Print.php

A critical SQL injection vulnerability has been identified in the Code-Projects Vehicle Management application, version 1.0. The issue resides in the print.php file, where the 'sno' parameter is manipulated, allowing attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, potentially 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 modification or deletion, and in some cases, could allow attackers to gain control over the application or server.

Reproduction

The vulnerability can be reproduced by sending a POST request to 'print.php' with the 'sno' parameter. Various payloads can be used to exploit the SQL injection, such as boolean-based blind injections or error-based injections that leverage SQL error messages to extract database information.

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.
