CVE-2026-2011: School Management System SQLi Vulnerability

CVE-2026-2011 Overview

CVE-2026-2011 is a SQL injection vulnerability in itsourcecode Student Management System 1.0. The flaw resides in the /ramonsys/enrollment/controller.php script, where the ID parameter is passed to a backend database query without proper sanitization. Remote attackers can manipulate the ID argument to inject arbitrary SQL statements. The issue is classified under CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements). Public disclosure of exploit details has occurred through VulDB, increasing the risk of opportunistic attacks against exposed installations.

Critical Impact
Unauthenticated remote attackers can manipulate database queries through the ID parameter, exposing student records and enabling unauthorized data modification.

Technical Details for CVE-2026-2011

Vulnerability Analysis

The vulnerability exists in the enrollment controller of the itsourcecode Student Management System. The controller.php script accepts an ID parameter via HTTP request and concatenates the value directly into a SQL statement. No prepared statements, parameterized queries, or input validation routines neutralize special characters before query execution.

An attacker can supply crafted input containing SQL metacharacters such as single quotes, UNION clauses, or comment sequences. The database engine then executes the injected payload with the privileges of the application's database account. Because the application is a PHP-based web system commonly deployed on shared hosting, the database account often has full read and write access to the application schema.

The attack requires no authentication and no user interaction, and it can be launched over the network. Exploit details have been published, so script-based scanning and automated exploitation are realistic threats.

Root Cause

The root cause is improper neutralization of user-supplied input used in SQL query construction. The application trusts the ID request parameter and embeds it into a dynamic query string. This pattern is the canonical SQL injection condition described in CWE-89.

Attack Vector

An attacker sends an HTTP request to /ramonsys/enrollment/controller.php with a malicious ID parameter. Payloads can extract data through UNION-based injection, exfiltrate records via boolean or time-based blind techniques, or modify rows using stacked queries where supported. See the GitHub Issue on CVE Discoveries and the VulDB #344593 Report for additional technical details.

Detection Methods for CVE-2026-2011

Indicators of Compromise

HTTP requests to /ramonsys/enrollment/controller.php containing SQL syntax such as UNION SELECT, OR 1=1, --, SLEEP(, or information_schema in the ID parameter.
Unexpected database errors logged by the PHP application or MySQL/MariaDB referencing the enrollment controller.
Outbound connections or large response payloads from the web server following requests to the vulnerable endpoint.

Detection Strategies

Deploy web application firewall (WAF) rules that inspect the ID parameter on the enrollment controller endpoint for SQL injection signatures.
Enable verbose query logging on the backend database and alert on anomalous queries originating from the application user.
Correlate HTTP access logs with database audit logs to identify injection attempts that produced abnormal result sets.

Monitoring Recommendations

Monitor for repeated 500-series responses or unusually long response times on /ramonsys/enrollment/ URIs, which often indicate blind injection attempts.
Track authentication anomalies and bulk record reads in the student database table.
Forward web and database logs to a centralized analytics platform to support retrospective hunting once new injection patterns are published.

How to Mitigate CVE-2026-2011

Immediate Actions Required

Restrict access to the Student Management System to trusted networks or authenticated VPN users until a fix is applied.
Audit the /ramonsys/enrollment/controller.php source and replace dynamic SQL with prepared statements using PDO or mysqli bound parameters.
Review database accounts used by the application and remove privileges beyond what the application requires.

Patch Information

No vendor patch or official advisory has been published by itsourcecode at the time of NVD publication. Administrators should monitor itsourcecode.com and the VulDB #344593 Details entry for remediation updates. Until a vendor fix is released, code-level mitigation by the operator is required.

Workarounds

Rewrite the affected query in controller.php to use parameterized queries and cast the ID value to an integer before use.
Deploy a WAF rule blocking SQL metacharacters in the ID parameter on the enrollment endpoint.
Place the application behind authentication-enforcing reverse proxy controls to reduce unauthenticated network exposure.

bash

# Example PHP fix pattern using PDO prepared statements
# Replace vulnerable concatenation in controller.php

# Before (vulnerable):
# $sql = "SELECT * FROM enrollment WHERE id = " . $_GET['ID'];

# After (safe):
# $stmt = $pdo->prepare("SELECT * FROM enrollment WHERE id = :id");
# $stmt->bindValue(':id', (int)$_GET['ID'], PDO::PARAM_INT);
# $stmt->execute();
