CVE-2026-14774: Hospital Management System SQLi Flaw

CVE-2026-14774 Overview

CVE-2026-14774 is a SQL injection vulnerability in itsourcecode Hospital Management System 1.0. The flaw resides in the /paymentdischarge.php script, where the patientid parameter is passed to a database query without proper sanitization. An authenticated remote attacker can manipulate this parameter to inject arbitrary SQL statements. The exploit has been publicly disclosed, increasing the likelihood of opportunistic abuse against exposed installations. This weakness is classified under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Attackers with low-privileged access can read, modify, or delete hospital records by injecting SQL through the patientid parameter in /paymentdischarge.php.

Affected Products

itsourcecode Hospital Management System 1.0
Component: /paymentdischarge.php
Affected parameter: patientid

Technical Details for CVE-2026-14774

Vulnerability Analysis

The vulnerability exists in the payment discharge workflow of itsourcecode Hospital Management System 1.0. The /paymentdischarge.php endpoint accepts a patientid parameter from the client and concatenates it into a SQL query without parameterization or input validation. This allows an attacker to break out of the intended query context and append arbitrary SQL clauses.

Exploitation requires network access to the application and low-privileged authentication. Successful injection can expose patient records, financial data, and credentials stored in the underlying database. The attacker can also modify or destroy records depending on the database user's privileges.

Because the exploit has been publicly disclosed through VulDB and a public GitHub issue, defenders should assume attackers have working payloads. Hospital Management System instances exposed to the internet face the highest risk.

Root Cause

The root cause is improper neutralization of user-supplied input in a SQL statement. The patientid value is inserted directly into the query string rather than passed as a bound parameter. No allow-list validation or type enforcement is applied before the database call.

Attack Vector

The attack is delivered over the network through an HTTP request to /paymentdischarge.php. An attacker who holds low-privileged credentials submits a crafted patientid value containing SQL metacharacters. The server executes the injected SQL against the backend database and returns results or errors that guide further exploitation. See the VulDB entry for CVE-2026-14774 and the GitHub issue discussion for additional technical context.

No verified proof-of-concept code is reproduced here. Refer to the VulDB vulnerability record for public technical details.

Detection Methods for CVE-2026-14774

Indicators of Compromise

HTTP requests to /paymentdischarge.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or OR 1=1 in the patientid parameter.
Web server or PHP error logs showing SQL syntax errors originating from paymentdischarge.php.
Unusual outbound database queries or large result sets tied to the hospital management application service account.

Detection Strategies

Deploy web application firewall (WAF) rules that flag SQL injection patterns targeting the patientid parameter on /paymentdischarge.php.
Enable database query auditing to identify anomalous SELECT, UNION, or INFORMATION_SCHEMA queries originating from the application user.
Correlate authentication events with subsequent injection attempts to detect low-privileged accounts probing the endpoint.

Monitoring Recommendations

Alert on HTTP 500 responses from /paymentdischarge.php, which often accompany failed injection probes.
Monitor for repeated requests to the same endpoint from a single source with varying patientid values.
Track database user activity for schema enumeration and dumps of the patients, payments, or users tables.

How to Mitigate CVE-2026-14774

Immediate Actions Required

Restrict network exposure of the Hospital Management System to trusted internal networks or authenticated VPN users.
Deploy a WAF rule blocking SQL metacharacters in the patientid parameter of /paymentdischarge.php.
Rotate database credentials and audit application accounts for signs of prior exploitation.
Review database logs for suspicious queries dated from the publication of the vulnerability forward.

Patch Information

At the time of publication, no vendor patch has been referenced in the NVD entry for CVE-2026-14774. Administrators should monitor the itsourcecode website for updates and apply source-level fixes that convert the affected query to a parameterized statement.

Workarounds

Modify /paymentdischarge.php to use prepared statements with bound parameters for the patientid value.
Enforce server-side input validation that restricts patientid to numeric characters only.
Apply the principle of least privilege to the database account used by the application, removing DROP, ALTER, and cross-database SELECT rights.
Disable or remove the /paymentdischarge.php endpoint if it is not required for operations until a fix is applied.
