CVE-2025-70063 in Hospital Management System
Summary
by MITRE • 02/18/2026
The 'Medical History' module in PHPGurukul Hospital Management System v4.0 contains an Insecure Direct Object Reference (IDOR) vulnerability. The application fails to verify that the requested 'viewid' parameter belongs to the currently authenticated patient. This allows a user to access the confidential medical records of other patients by iterating the 'viewid' integer.

The CVE-2025-70063 vulnerability represents a critical Insecure Direct Object Reference flaw within the Medical History module of PHPGurukul Hospital Management System version 4.0. This vulnerability stems from insufficient access control mechanisms that fail to validate whether a requesting user has legitimate authorization to access specific patient medical records. The system operates under the assumption that all users with valid session credentials can access any patient record by simply manipulating the viewid parameter, creating an exploitable gap in the application's security architecture.
The technical implementation of this vulnerability occurs through the improper validation of user input within the Medical History module. When a user requests to view medical records, the application accepts a viewid parameter without performing proper authorization checks against the current session's authenticated user context. This allows an attacker to iterate through sequential viewid integers and access confidential medical information belonging to other patients within the system. The vulnerability is classified as CWE-284 Access Control Issues, specifically manifesting as an Insecure Direct Object Reference where the application directly references objects using user-supplied input without proper access validation.
The operational impact of this vulnerability extends beyond simple data exposure, creating significant risks for patient privacy and healthcare compliance. An attacker can systematically enumerate patient records through simple parameter manipulation, potentially accessing hundreds or thousands of medical histories without proper authorization. This breach directly violates healthcare privacy regulations including HIPAA and GDPR requirements for patient data protection, as it enables unauthorized access to sensitive medical information such as diagnoses, treatments, medications, and personal health details. The vulnerability affects the confidentiality and integrity of the entire patient database, potentially exposing sensitive information that could be used for identity theft, insurance fraud, or other malicious activities.
Mitigation strategies for CVE-2025-70063 must focus on implementing robust access control mechanisms and proper input validation. The system should enforce session-based authentication checks before allowing access to any patient medical records, ensuring that the viewid parameter corresponds to the authenticated user's own patient ID. Implementing proper authorization controls through the principle of least privilege will prevent unauthorized access to patient data. Additionally, the application should implement rate limiting and logging mechanisms to detect and prevent automated enumeration attempts. Security measures should include proper parameter validation, session management improvements, and comprehensive access control checks that align with NIST cybersecurity frameworks. The fix requires modifications to the Medical History module to validate that each requested viewid belongs to the currently authenticated user, preventing the direct object reference vulnerability that enables cross-patient data access. Organizations should also implement regular security testing including penetration testing and code reviews to identify similar access control flaws in healthcare applications.
