CVE-2026-14717: Hospital Management System SQLi Vulnerability

CVE-2026-14717 Overview

CVE-2026-14717 is a SQL injection vulnerability in itsourcecode Hospital Management System 1.0. The flaw resides in /patientlogin.php, where the loginid parameter is passed to a backend database query without proper sanitization. Attackers can manipulate this parameter to inject arbitrary SQL statements. The vulnerability is remotely exploitable over the network and requires low-privilege authentication. Public exploit details have been disclosed, increasing the likelihood of opportunistic abuse against exposed installations. The issue is categorized under [CWE-74] (Improper Neutralization of Special Elements in Output).

Critical Impact
Authenticated remote attackers can inject SQL through the loginid parameter in /patientlogin.php, potentially exposing patient records and other sensitive data stored in the hospital database.

Affected Products

itsourcecode Hospital Management System 1.0
/patientlogin.php component
Deployments using the vulnerable loginid parameter handling

Technical Details for CVE-2026-14717

Vulnerability Analysis

The vulnerability exists in the patient login workflow of itsourcecode Hospital Management System 1.0. The /patientlogin.php endpoint accepts the loginid parameter from user input and incorporates it directly into a SQL query. Because the application does not use parameterized statements or apply input validation, an attacker can break out of the intended query context. This allows execution of attacker-controlled SQL against the underlying database.

An attacker exploiting this flaw can read, modify, or delete records stored by the application. In hospital management deployments, affected data typically includes patient identifiers, appointment records, and staff credentials. Successful exploitation can also enable authentication bypass by tampering with login logic.

Root Cause

The root cause is improper neutralization of special SQL elements in the loginid request parameter. The application concatenates untrusted input into a query string rather than binding parameters. This design flaw maps to [CWE-74] and is a common failure mode in legacy PHP applications that build SQL through string interpolation.

Attack Vector

Exploitation occurs over the network against the login endpoint. The attacker submits a crafted loginid value containing SQL metacharacters through a standard HTTP POST or GET request. No user interaction is required beyond authentication at a low privilege level. Public disclosure through the GitHub Issue Tracker and VulDB CVE-2026-14717 makes exploitation straightforward for attackers with basic SQL injection tooling.

Detection Methods for CVE-2026-14717

Indicators of Compromise

HTTP requests to /patientlogin.php containing SQL metacharacters such as ', --, UNION, or OR 1=1 in the loginid parameter.
Database error messages returned in application responses referencing SQL syntax errors on the login page.
Unexpected authentication events from IP addresses submitting malformed loginid values.
Anomalous query patterns in database logs originating from the web application service account.

Detection Strategies

Deploy web application firewall rules that flag SQL injection payloads targeting /patientlogin.php and the loginid parameter.
Correlate web server access logs with database query logs to identify injection attempts followed by unusual result sets.
Monitor for repeated failed login attempts combined with SQL metacharacters, which indicate automated exploitation attempts.

Monitoring Recommendations

Enable verbose logging on the PHP application and forward logs to a centralized SIEM for query pattern analysis.
Alert on database queries that access large volumes of patient records outside expected business hours.
Track outbound traffic from the web server host for signs of data exfiltration following suspicious login activity.

How to Mitigate CVE-2026-14717

Immediate Actions Required

Restrict network access to the Hospital Management System until a fix is applied, using firewall rules or VPN-only access.
Audit the /patientlogin.php source code and refactor SQL queries to use prepared statements with bound parameters.
Review database logs for signs of exploitation predating disclosure, including unexpected SELECT or UNION-based queries.
Rotate database credentials and any patient or staff passwords that may have been exposed.

Patch Information

No official vendor patch has been published at the time of writing. Consult the ItSourceCode Homepage and the VulDB Vulnerability #376306 entry for updates. Organizations running the affected version should apply source-level fixes independently until a vendor release is available.

Workarounds

Place the application behind a web application firewall configured to block SQL injection payloads on the login endpoint.
Implement input validation to reject loginid values containing non-alphanumeric characters before they reach the database layer.
Apply least-privilege permissions to the database account used by the web application, limiting it to only the tables and operations required.
Disable public internet exposure of the Hospital Management System and require authenticated VPN access.
