Campcodes Online Hospital Management System SQL Injection Vulnerability

A critical SQL injection vulnerability has been identified in Campcodes Online Hospital Management System version 1.0. The issue resides in the file '/hms/admin/betweendates-detailsreports.php', where the 'fromdate' and 'todate' parameters are manipulated 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 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 '/hms/admin/betweendates-detailsreports.php' with crafted 'fromdate' and 'todate' parameters that include SQL injection payloads. The injected SQL code is executed by the application, allowing the attacker to manipulate the database. This exploitation can be automated using tools like sqlmap, which can extract database information and potentially exploit the application further.

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.
