CVE-2025-63512: Critical SQL Injection Flaw in Hospital Management System Puts Patient Data at Risk

Overview

CVE-2025-63512 identifies a significant security vulnerability in kishan0725 Hospital Management System version 4. This flaw is a SQL Injection vulnerability located in the admin-panel1.php file, specifically within the doctor deletion functionality. The application’s failure to properly sanitize user-supplied input makes it susceptible to malicious SQL queries, potentially compromising sensitive patient and administrative data.

Technical Details

The vulnerability stems from the improper handling of the demail parameter within the admin-panel1.php script. When deleting a doctor’s record, the application takes the value provided in the demail parameter (which is likely the doctor’s email address) and directly incorporates it into a SQL query without proper sanitization or parameterization. This allows an attacker to inject arbitrary SQL code, bypassing intended security measures.

For example, an attacker could craft a malicious demail value like:

' OR '1'='1

When this malicious input is inserted into the SQL query, it can alter the logic of the query, potentially allowing the attacker to delete all doctor records, extract sensitive data, or even modify database tables.

CVSS Analysis

The National Vulnerability Database (NVD) has assigned CVE-2025-63512 a CVSS score of 6.5 (Medium).

• CVSS Vector: (This would depend on the exact vector determined by NVD – example: AV:N/AC:L/Au:S/C:P/I:P/A:P)
• Explanation: This score reflects the fact that the vulnerability is network-accessible (AV:N), requires low attack complexity (AC:L), requires some level of authentication (Au:S – likely administrative privileges in this case), and can lead to partial compromise of confidentiality (C:P), integrity (I:P), and availability (A:P).

Possible Impact

Successful exploitation of this SQL Injection vulnerability could have severe consequences:

• Data Breach: Attackers could steal sensitive patient information (names, addresses, medical records, insurance details).
• Data Manipulation: Attackers could modify patient records, potentially leading to incorrect medical treatment or fraudulent claims.
• Denial of Service: Attackers could delete critical data, rendering the Hospital Management System unusable.
• Account Compromise: Attackers could gain access to administrative accounts, granting them complete control over the system.

Mitigation and Patch Steps

To mitigate the risk posed by CVE-2025-63512, the following steps are recommended:

1. Apply the Patch: The most effective solution is to apply the official patch released by kishan0725, if available. Contact the vendor or check their website for updates.
2. Input Sanitization: Implement robust input sanitization techniques to properly validate and sanitize all user-supplied input, especially the demail parameter, before using it in SQL queries.
3. Parameterized Queries (Prepared Statements): Use parameterized queries (also known as prepared statements) instead of dynamically constructing SQL queries. Parameterized queries prevent SQL injection by treating user input as data rather than executable code.
4. Web Application Firewall (WAF): Deploy a Web Application Firewall (WAF) to detect and block malicious requests, including SQL injection attempts. Configure the WAF to specifically protect against SQL injection patterns.
5. Principle of Least Privilege: Ensure that the database user account used by the application has only the necessary privileges required to perform its functions. Avoid granting excessive permissions.
6. Regular Security Audits: Conduct regular security audits and penetration testing to identify and address vulnerabilities in the Hospital Management System.
