Overview
Security vulnerabilities in medical practice management systems can pose severe threats to the integrity and confidentiality of sensitive patient data. The CVE-2025-3708 is a prime example of such a vulnerability, affecting the Le-show medical practice management system from Le-yan. This high-risk SQL Injection vulnerability allows unauthenticated remote attackers to execute arbitrary SQL commands, potentially leading to unauthorized access and modification of database contents. As such, it is a significant concern for healthcare providers using the affected system and warrants immediate attention and rectification.

How the Exploit Works
The exploit works by taking advantage of insufficient input sanitization within the Le-show system. This vulnerability allows an attacker to inject malicious SQL queries into the system, which are then executed by the database. As no authentication is required, a remote attacker can exploit this vulnerability to interact with the database, potentially leading to unauthorized access, alteration, or deletion of data.
Conceptual Example Code
Below is a conceptual example of how the vulnerability might be exploited. Please note this is not actual exploit code, but a demonstration of the type of malicious SQL query an attacker might use:
POST /Le-show/login HTTP/1.1
Host: target.example.com
Content-Type: application/x-www-form-urlencoded
username=admin'; DROP TABLE Patients; --&password=testIn this example, the SQL command ‘DROP TABLE Patients’ is injected into the ‘username’ field of a login request. If the system is vulnerable, this command will delete the ‘Patients’ table from the database.
Mitigation Guidance
To mitigate this vulnerability, users should immediately apply the vendor-supplied patch. If this is not possible, a Web Application Firewall (WAF) or Intrusion Detection System (IDS) could be used as a temporary mitigation measure. These tools can help to filter out SQL Injection attacks by identifying and blocking malicious SQL commands. However, these are not long-term solutions and cannot fully guarantee protection against the vulnerability. As such, applying the vendor patch should be prioritized to fully address the security flaw.
