The itsourcecode Hospital Management System 1.0 contains a SQL injection vulnerability in the /payment.php file. Specifically, the patientid parameter is not properly sanitized, allowing an attacker to inject malicious SQL commands. This vulnerability can be exploited remotely without user interaction and requires only low privileges. The vulnerability has been publicly disclosed, but no known exploits in the wild have been reported. No official fix or patch has been provided as of the publication date.

Successful exploitation of this vulnerability could allow an attacker to execute arbitrary SQL commands on the backend database. This may lead to unauthorized data access, data modification, or other database-related impacts depending on the database permissions. The vulnerability affects confidentiality, integrity, and availability to a limited extent as indicated by the CVSS vector components (VC:L, VI:L, VA:L).

Patch status is not yet confirmed — check the vendor advisory for current remediation guidance. Until an official fix is available, users should consider implementing input validation or parameterized queries on the patientid parameter to mitigate SQL injection risks. Monitoring and restricting access to the affected endpoint may also reduce exposure.
