How the Exploit Works
The exploit takes advantage of insufficient input validation in the ‘about-us.php’ file of the phpgurukul Hospital Management System 4.0. The ‘pagetitle’ parameter in the file is susceptible to SQL Injection attacks. An attacker can craft malicious SQL commands and include them in the ‘pagetitle’ parameter. When this parameter is processed by the backend server, the malicious SQL commands get executed, potentially leading to unauthorized access, data manipulation, or data leakage.
Conceptual Example Code
Below is a conceptual example of how an attacker might exploit this vulnerability using an HTTP POST request:
POST /about-us.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
pagetitle='; DROP TABLE Patients; --In the above code, the value of the ‘pagetitle’ parameter is a malicious SQL command (‘; DROP TABLE Patients; –‘) aiming to delete the Patients table from the database.
Mitigation and Prevention
There are two recommended courses of action to mitigate this vulnerability. The first and most effective solution is to apply a vendor-supplied patch. If such a patch is not immediately available, implementing a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can serve as a temporary mitigation measure. Additionally, to prevent such vulnerabilities, it’s advisable to follow secure coding practices, such as proper input validation and parameterized queries.
