CVE-2026-11514: Hospital Management System SQLi Flaw

CVE-2026-11514 Overview

CVE-2026-11514 is a SQL injection vulnerability in itsourcecode Hospital Management System 1.0. The flaw resides in the /addpatient.php script, where the admissiontme parameter is incorporated into a database query without proper sanitization. An authenticated remote attacker can manipulate this parameter to inject arbitrary SQL statements. The vulnerability is categorized under CWE-74 (Improper Neutralization of Special Elements in Output). Public exploit details have been disclosed through VulDB CVE-2026-11514 and a GitHub Issue Discussion.

Critical Impact
Remote authenticated attackers can inject SQL through the admissiontme parameter to read, modify, or delete patient and hospital records.

Technical Details for CVE-2026-11514

Vulnerability Analysis

The vulnerability exists in the patient admission workflow of the Hospital Management System. The /addpatient.php script accepts user-supplied input through the admissiontme parameter and concatenates it directly into a SQL statement. Because no parameterized queries or input validation are applied, an attacker can inject arbitrary SQL syntax.

The attack requires low privileges, no user interaction, and can be performed over the network. Successful exploitation enables data exfiltration from backend MySQL tables holding patient records, staff credentials, and billing information. Depending on the privileges of the database account used by the application, an attacker may also write to or delete records.

The weakness is classified under CWE-74 (Improper Neutralization of Special Elements). The vendor itsourcecode publishes the affected codebase on the IT Source Code Blog, and additional technical context is available through the VulDB Vulnerability #369134 entry.

Root Cause

The root cause is unsanitized concatenation of HTTP request parameters into SQL queries. The admissiontme field, intended to capture an admission timestamp, is passed directly into the query string without type checking, escaping, or prepared statement binding.

Attack Vector

An attacker authenticates to the application with any valid low-privilege account, then submits a crafted POST or GET request to /addpatient.php with a malicious payload in the admissiontme parameter. Standard SQL injection techniques such as UNION-based extraction or boolean blind injection apply. The exploit has been published, as documented in the VulDB Submission #836163.

The vulnerability mechanism is described in the referenced sources without verified proof-of-concept code being mirrored here. Refer to the GitHub Issue Discussion and VulDB CTI for #369134 for additional technical details.

Detection Methods for CVE-2026-11514

Indicators of Compromise

HTTP requests to /addpatient.php containing SQL metacharacters such as single quotes, UNION, SELECT, --, or /* within the admissiontme parameter.
Database error messages logged by PHP referencing syntax errors near admissiontme values.
Unexpected outbound database queries originating from the web application server during patient registration workflows.

Detection Strategies

Inspect web server access logs for anomalous values in the admissiontme POST or GET parameter that deviate from expected timestamp formats.
Deploy a web application firewall ruleset that flags SQL injection payload signatures on the /addpatient.php endpoint.
Correlate authentication events with subsequent database errors to identify probing behavior from low-privilege accounts.

Monitoring Recommendations

Enable MySQL general query logging temporarily to capture queries originating from the Hospital Management System application.
Alert on any HTTP 500 responses returned by /addpatient.php that may indicate failed injection attempts.
Monitor for bulk data reads from sensitive patient tables outside normal business hours.

How to Mitigate CVE-2026-11514

Immediate Actions Required

Restrict network access to the Hospital Management System to trusted internal segments until a fix is applied.
Audit user accounts and disable any non-essential low-privilege users that could be abused to reach /addpatient.php.
Review database account permissions used by the application and apply least privilege to limit injection impact.

Patch Information

No official vendor patch has been published at the time of NVD release. Consult the IT Source Code Blog for vendor updates and the VulDB CVE-2026-11514 record for fix tracking. Until a patch is available, source-level remediation requires replacing dynamic SQL with parameterized queries using PHP PDO or mysqli prepared statements.

Workarounds

Implement server-side input validation that enforces a strict timestamp format on the admissiontme parameter and rejects any non-conforming input.
Deploy a web application firewall in front of the application with SQL injection rules tuned for the /addpatient.php endpoint.
Refactor the affected query to use prepared statements, binding admissiontme as a typed parameter rather than concatenating it into the SQL string.
