CVE-2025-69942: Hospital Management System SQLi Vulnerability

CVE-2025-69942 is a SQL injection vulnerability in Hospital Management System 4.0 affecting the view-patient.php endpoint. Attackers can exploit this flaw to access or manipulate database contents. This article covers technical details, affected versions, impact assessment, and mitigation strategies.

CVE-2025-69942 Overview

CVE-2025-69942 is a SQL Injection vulnerability affecting kishan0725 Hospital Management System version 4.0. The flaw resides in the /hms/doctor/view-patient.php endpoint, where the viewid parameter is passed to a database query without proper sanitization. An attacker can manipulate the viewid value to inject arbitrary SQL statements and interact directly with the backing database.

Because the affected endpoint is part of the doctor-facing patient view workflow, successful exploitation exposes sensitive patient records and administrative data. The vulnerability is tracked as [CWE-89] SQL Injection.

Critical Impact
Attackers can extract, modify, or destroy patient data stored in the Hospital Management System database by injecting SQL through the viewid GET parameter.

Technical Details for CVE-2025-69942

Vulnerability Analysis

The Hospital Management System is a PHP-based web application that manages patient, doctor, and appointment data. The view-patient.php script in the doctor directory accepts a viewid value via HTTP GET and uses it to look up a patient record. The application concatenates this user-controlled input directly into a SQL query rather than using prepared statements or parameterized queries.

An unauthenticated or low-privileged attacker who can reach the endpoint can supply crafted SQL syntax through viewid. The database engine then executes the attacker-controlled SQL alongside the intended query. This allows extraction of arbitrary tables, authentication bypass through UNION-based payloads, and modification of records. Public technical analysis is available in the TaintRadar SQL Injection CVE writeup.

Root Cause

The root cause is missing input validation and unsafe string concatenation when building the SQL query for viewid. The viewid value flows from the HTTP request into a query string executed against the MySQL backend without type coercion, escaping, or prepared-statement binding.

Attack Vector

Exploitation is remote and requires only network access to the vulnerable HTTP endpoint. An attacker issues a request such as GET /hms/doctor/view-patient.php?viewid=1' UNION SELECT ...-- and observes response content or timing differences to enumerate the database schema. Boolean-based, UNION-based, and time-based blind SQL injection techniques are all viable against a query of this form.

See the TaintRadar advisory for reproduction details.

Detection Methods for CVE-2025-69942

Indicators of Compromise

HTTP requests to /hms/doctor/view-patient.php containing SQL metacharacters in the viewid parameter, such as single quotes, UNION, SELECT, SLEEP, or comment sequences (--, #, /*).
Unusually long viewid values or values that are not simple integers.
Web server or PHP error logs referencing MySQL syntax errors originating from view-patient.php.

Detection Strategies

Deploy a web application firewall rule that inspects the viewid query parameter and rejects non-numeric input.
Correlate database error responses with the originating client IP to identify enumeration attempts.
Hunt for spikes in requests to view-patient.php from a single source with varying viewid payloads, which indicates automated SQLi tooling such as sqlmap.

Monitoring Recommendations

Enable MySQL general query logging for the Hospital Management System database and alert on queries containing UNION SELECT originating from the web application user.
Monitor egress traffic from the web server for anomalous data transfer volumes that could indicate database exfiltration.
Track authentication activity in the application immediately after suspicious viewid requests, as attackers may pivot to credential theft.

How to Mitigate CVE-2025-69942

Immediate Actions Required

Restrict access to /hms/doctor/view-patient.php behind authenticated sessions and network controls until a code fix is deployed.
Deploy a WAF rule that enforces a numeric-only pattern on the viewid parameter.
Review database and web server logs for prior exploitation attempts against the endpoint.

Patch Information

No vendor patch is referenced in the NVD entry at the time of publication. Administrators should refer to the kishan0725 Hospital Management System repository for updates and apply a code-level fix that replaces string concatenation with parameterized queries using mysqli_prepare or PDO prepared statements.

Workarounds

Cast viewid to an integer server-side before use, for example $viewid = (int) $_GET['viewid'];, and reject any request where the cast changes the value.
Apply least-privilege on the database account used by the application so it cannot read or modify tables outside its required scope.
Place the application behind a reverse proxy that enforces strict input validation on all query parameters.

bash

# Example WAF rule (ModSecurity) to block non-numeric viewid values
SecRule ARGS:viewid "!@rx ^[0-9]+$" \
  "id:1069942,phase:2,deny,status:400,\
   msg:'CVE-2025-69942 - Non-numeric viewid blocked on view-patient.php',\
   chain"
  SecRule REQUEST_URI "@contains /hms/doctor/view-patient.php"
