CVE-2025-70062 Overview
PHPGurukul Hospital Management System v4.0 contains a Cross-Site Request Forgery (CSRF) vulnerability in the 'Add Doctor' module. The application fails to enforce CSRF token validation on the add-doctor.php endpoint. This allows remote attackers to create arbitrary Doctor accounts (privileged users) by tricking an authenticated administrator into visiting a malicious page.
Critical Impact
Attackers can create unauthorized privileged Doctor accounts by exploiting the missing CSRF protection, potentially leading to unauthorized access to sensitive patient data and administrative functions within the hospital management system.

Technical Details for CVE-2025-70062
Vulnerability Analysis
This Cross-Site Request Forgery (CSRF) vulnerability exists in the PHPGurukul Hospital Management System due to the absence of anti-CSRF token validation on the add-doctor.php endpoint. When an authenticated administrator is logged into the system, an attacker can craft a malicious webpage containing a forged HTTP request that targets the Add Doctor functionality. If the administrator visits this malicious page while their session is active, the browser automatically includes their session credentials, causing the forged request to execute with administrative privileges.
The vulnerability is classified under CWE-352 (Cross-Site Request Forgery). The attack requires user interaction—specifically, the administrator must be tricked into visiting a malicious page while authenticated. However, no prior privileges or authentication on the target system are required by the attacker to initiate the attack.
Root Cause
The root cause of this vulnerability is the failure to implement proper CSRF token validation in the add-doctor.php endpoint. The application does not generate, embed, or validate unique anti-CSRF tokens in form submissions, allowing state-changing requests to be forged from external sources. Modern web application security standards require that all state-changing operations include a cryptographically random token that is validated server-side to prevent such attacks.
Attack Vector
The attack is network-based and requires the attacker to craft a malicious HTML page containing a form or JavaScript that automatically submits a request to the vulnerable add-doctor.php endpoint. The attacker must then social engineer an authenticated administrator into visiting this malicious page. When the administrator's browser loads the page, it automatically sends the forged request along with the administrator's valid session cookies, causing the Hospital Management System to process the request as if it were legitimately initiated by the administrator.
The malicious page could be hosted on any external website, sent via phishing email, or embedded in a compromised legitimate site. Upon successful exploitation, a new Doctor account with elevated privileges is created in the system without the administrator's knowledge or consent.
Detection Methods for CVE-2025-70062
Indicators of Compromise
- Unexpected Doctor accounts appearing in the Hospital Management System user database
- Administrator access logs showing account creation requests originating from unusual referrer URLs or external domains
- Web server logs indicating POST requests to add-doctor.php with referrer headers pointing to external websites
Detection Strategies
- Monitor web application logs for POST requests to add-doctor.php that originate from referrers outside the trusted domain
- Implement alerting for any new Doctor account creation events and validate them against authorized administrative actions
- Deploy Web Application Firewall (WAF) rules to detect and block requests lacking proper origin validation
Monitoring Recommendations
- Enable detailed logging for all administrative functions, particularly user account management endpoints
- Configure security information and event management (SIEM) alerts for unusual patterns in account creation activity
- Regularly audit the user database for unauthorized or unexpected privileged accounts
How to Mitigate CVE-2025-70062
Immediate Actions Required
- Review and audit all existing Doctor accounts in the system to identify any unauthorized entries
- Implement CSRF token validation on the add-doctor.php endpoint and all other state-changing forms
- Consider restricting administrative access to trusted networks or requiring additional authentication factors for sensitive operations
- Educate administrators about phishing risks and the importance of not clicking untrusted links while logged into administrative interfaces
Patch Information
No official vendor patch has been identified at this time. Administrators should apply manual mitigations or consider implementing custom CSRF protection. Technical details and proof-of-concept information are available through the external references:
Workarounds
- Implement custom CSRF token generation and validation on all form submissions in the application
- Configure the web server to validate the Origin and Referer headers for administrative endpoints
- Use the SameSite=Strict cookie attribute to prevent session cookies from being sent with cross-site requests
- Deploy a Web Application Firewall (WAF) with CSRF protection rules enabled
# Example: Setting SameSite cookie attribute in PHP configuration
# Add to php.ini or application configuration
session.cookie_samesite = "Strict"
