Overview
The Common Vulnerabilities and Exposures (CVE) system has recently identified a severe security vulnerability in the Hospital Management System 4.0 by phpgurukul. This vulnerability, designated CVE-2025-56212, exposes the system to SQL Injection attacks via the ‘docname’ parameter in the ‘add-doctor.php’ file. As Hospital Management Systems store and manage sensitive patient information, this vulnerability could lead to the compromise of critical patient data and system integrity if left unpatched. It’s imperative for stakeholders to understand the severity and potential impact of this vulnerability and take immediate steps to mitigate its effects.

How the Exploit Works
The exploitation of this vulnerability involves the manipulation of input data within the ‘docname’ parameter of the ‘add-doctor.php’ file. An attacker could craft malicious SQL commands and inject them into this parameter. As the system is not properly sanitizing user inputs, the SQL commands would be executed directly on the database, leading to unauthorized read/write operations. This could result in unauthorized access, data corruption, or even total system compromise.
Conceptual Example Code
Here is a conceptual example of how this vulnerability might be exploited. In this case, an HTTP POST request is sent with a malicious SQL command embedded in the ‘docname’ parameter:
POST /add-doctor.php HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
docname=' OR '1'='1; DROP TABLE users; --In this example, the SQL command `’ OR ‘1’=’1; DROP TABLE users; –` would delete the entire ‘users’ table from the database, leading to significant data loss and system disruption.
Mitigation Actions
To mitigate this vulnerability, it is recommended that users immediately apply the vendor patch once it becomes available. In the meantime, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) can be used to monitor and filter out suspicious traffic. Regularly updating and patching software, as well as implementing proper input sanitization techniques, can also help prevent similar vulnerabilities in the future.
