SQL Injection Vulnerability in projectworlds hospital-management-system-in-php 1.0 (CVE-2026-8785)

A SQL injection vulnerability, identified as CVE-2026-8785, has been discovered in projectworlds hospital-management-system-in-php version 1.0. The vulnerability resides within the getAllPatientDetail function in the update_info.php file. A remote attacker can exploit this flaw by manipulating the appointment_no GET parameter. The vendor has been notified, but has not yet responded or provided a patch. Publicly available exploits exist, making this vulnerability a significant risk.

Attack Chain

1. The attacker identifies an instance of projectworlds hospital-management-system-in-php version 1.0.
2. The attacker crafts a malicious HTTP GET request targeting the update_info.php file.
3. The attacker injects SQL code into the appointment_no parameter of the GET request.
4. The webserver processes the request and passes the appointment_no parameter to the getAllPatientDetail function without proper sanitization.
5. The injected SQL code is executed against the database.
6. The attacker retrieves sensitive data from the database, such as patient records or credentials.
7. The attacker may modify or delete data within the database.
8. The attacker may use the compromised database to further compromise the system or other connected systems.

Impact

Successful exploitation of this vulnerability allows an attacker to execute arbitrary SQL commands. This can lead to the disclosure of sensitive patient data, modification or deletion of records, and potential compromise of the entire application and underlying database server. Given the nature of the application, this could result in severe breaches of patient privacy, financial losses, and reputational damage for the affected healthcare organization.

Recommendation

• Inspect web server logs for suspicious GET requests to update_info.php containing SQL syntax in the appointment_no parameter and deploy the “Detect CVE-2026-8785 Exploitation via SQL Injection” Sigma rule.
• Apply input validation and sanitization to the appointment_no parameter in the getAllPatientDetail function to prevent SQL injection. Contact the vendor for a patch or apply a hotfix.
• Monitor database logs for unauthorized access or modification attempts originating from the web server.
• Implement the “Detect SQL Injection Characters in HTTP GET Parameters” Sigma rule to broadly detect potential SQL injection attempts.
