CVE-2026-78112: Hospital Management System SQL Injection

CVE-2026-78112 Overview

CVE-2026-78112 is a SQL injection vulnerability in itsourcecode Hospital Management System Project in PHP 1.0. The flaw resides in the /viewservicetype.php file, where the delid parameter is passed directly into a database query without sanitization. Remote attackers can manipulate the parameter to inject arbitrary SQL statements. The exploit has been published publicly, lowering the barrier to abuse. The weakness is tracked under [CWE-74] (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

Critical Impact
Authenticated remote attackers can inject SQL through the delid parameter of /viewservicetype.php, exposing patient and hospital records to unauthorized read, modification, or deletion.

Technical Details for CVE-2026-78112

Vulnerability Analysis

The vulnerability affects the /viewservicetype.php endpoint in the Hospital Management System web application. The script accepts a delid HTTP parameter and concatenates it into a SQL statement without input validation or parameterized queries. An attacker who can reach the application over the network and holds low-privilege credentials can supply crafted values to alter query logic. Successful injection allows unauthorized queries against the underlying MySQL database. According to the exploit prediction score, the near-term probability of exploitation is 0.25%.

Root Cause

The root cause is missing input neutralization on the delid parameter before it reaches the SQL execution layer. PHP source concatenates user input directly into query strings instead of using prepared statements or parameter binding. This pattern is a classic instance of [CWE-74] injection weaknesses.

Attack Vector

The attack is remote and requires low privileges but no user interaction. An attacker sends an HTTP request to /viewservicetype.php with a manipulated delid value containing SQL syntax. The injected payload executes within the context of the database user, enabling data extraction through UNION-based queries or boolean and time-based blind techniques. No authentication bypass is required beyond a low-privilege session.

See the VulDB Vulnerability Details and the public GitHub Issue Tracker for the disclosed proof-of-concept details.

Detection Methods for CVE-2026-78112

Indicators of Compromise

HTTP requests to /viewservicetype.php containing SQL meta-characters in the delid parameter, such as single quotes, UNION SELECT, SLEEP(, --, or /*.
Unusual outbound database queries or spikes in query volume from the web application user.
Web server logs showing repeated requests to viewservicetype.php from a single source with varying delid values.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the delid query string parameter for SQL syntax and reject known injection payloads.
Enable database query logging and alert on statements containing tautologies such as OR 1=1 or stacked queries originating from the application account.
Correlate web access logs with database audit logs to identify request-to-query patterns consistent with injection probing.

Monitoring Recommendations

Monitor authentication events for low-privilege accounts accessing hospital administration URLs at unusual times.
Track HTTP 500 responses on /viewservicetype.php, which often accompany blind SQL injection probing.
Ingest web server, PHP error, and database logs into a centralized analytics platform to enable retrospective hunting once new payloads are disclosed.

How to Mitigate CVE-2026-78112

Immediate Actions Required

Restrict access to /viewservicetype.php to trusted networks or authenticated administrators until a vendor patch is available.
Deploy WAF signatures that block SQL injection patterns targeting the delid parameter.
Rotate database credentials used by the application and confirm the account holds least-privilege permissions.
Review web and database logs for prior exploitation attempts referencing viewservicetype.php.

Patch Information

No official vendor patch is listed in the NVD entry at the time of publication. Consult the IT Source Code Homepage for vendor updates and the VulDB CVE Summary for tracking status. Administrators running production deployments should apply source-level fixes by converting the affected query to a prepared statement using mysqli_prepare or PDO with parameter binding.

Workarounds

Modify viewservicetype.php to cast delid to an integer using intval($_GET['delid']) before use in any SQL statement.
Replace inline queries with parameterized statements using PDO or mysqli prepared statements.
Enforce input allow-lists that accept only numeric identifiers for the delid parameter.
Isolate the application behind a reverse proxy with request filtering until code-level remediation is deployed.
