Projectworlds Gate Pass Management System SQL Injection Vulnerability

A SQL injection vulnerability has been identified in Projectworlds Gate Pass Management System version 1.0. The issue arises in the file '/add-pass.php', where insufficient validation of the 'fullname' parameter allows attackers to inject malicious SQL queries. This vulnerability can be exploited remotely, without any authentication, leading to unauthorized database access, data manipulation, and potential 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 the '/add-pass.php' file with a crafted 'fullname' parameter that includes malicious SQL payloads. The injection takes advantage of the application's failure to properly sanitize user input, allowing the injected SQL code to be executed by the database.

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.
