Executive Summary

[{'type': 'paragraph', 'content': "CVE-2025-70062 is a Cross-Site Request Forgery (CSRF) vulnerability found in the PHPGurukul Hospital Management System version 4.0, specifically in the 'Add Doctor' module. The application does not enforce CSRF token validation on the add-doctor.php endpoint. This flaw allows a remote attacker to trick an authenticated administrator into visiting a malicious webpage, which then causes the system to create arbitrary Doctor accounts without the administrator's consent."}] [1]

Detection Guidance

[{'type': 'paragraph', 'content': 'This vulnerability can be detected by verifying whether the add-doctor.php endpoint enforces CSRF token validation. One practical approach is to attempt to perform the add doctor action without a valid CSRF token and observe if the request is accepted.'}, {'type': 'paragraph', 'content': 'Since the vulnerability involves a lack of CSRF protection, you can use tools like curl or Burp Suite to send POST requests to the add-doctor.php endpoint without including a CSRF token and check if the server processes the request.'}, {'type': 'list_item', 'content': 'Example curl command to test the vulnerability (replace URL and parameters accordingly):'}, {'type': 'list_item', 'content': 'curl -X POST https://targetsite.com/add-doctor.php -d "doctor_name=Test&specialization=Test" --cookie "PHPSESSID=your_session_id"'}, {'type': 'paragraph', 'content': 'If the request succeeds without requiring a CSRF token, the vulnerability is present.'}] [1]

Mitigation Strategies

To mitigate this CSRF vulnerability, immediately implement CSRF token validation on the add-doctor.php endpoint to ensure that all requests to add a doctor include a valid, unique token tied to the user's session.

Additionally, educate administrators to avoid clicking on suspicious links while authenticated, as the vulnerability relies on tricking an authenticated user.

If possible, restrict access to the add-doctor.php functionality to trusted IP addresses or networks until a proper fix is deployed.
