Campcodes Online Hospital Management System SQL Injection Vulnerability in View Patient File

A critical SQL injection vulnerability has been identified in Campcodes Online Hospital Management System version 1.0. The issue resides in the admin view-patient.php file, where the viewid parameter is manipulated to inject malicious SQL queries. This vulnerability can be exploited remotely, allowing attackers to gain unauthorized access to the database, leak sensitive information, alter or delete data, and potentially disrupt services.

Impact

Exploitation of this vulnerability allows for unauthorized database access, manipulation of database contents, leakage of sensitive information, and could lead to a complete compromise of the system.

Reproduction

The vulnerability can be reproduced by sending a crafted HTTP request to the view-patient.php file with a manipulated viewid parameter. This can be done using a web browser or a tool like sqlmap, which automates the process of finding and exploiting SQL injection vulnerabilities. The injection can be verified by using payloads that, for example, bypass authentication or extract database information.

Remediation

To address this vulnerability, it is recommended to use prepared statements and parameter binding to prevent SQL injection. Additionally, input validation and filtering should be implemented to ensure that user input conforms to expected formats. Minimizing database user permissions and conducting regular security audits can also help enhance the overall security of the application.
