CVE-2026-2014: School Management System SQL Injection Flaw

CVE-2026-2014 Overview

A SQL injection vulnerability has been discovered in itsourcecode Student Management System version 1.0. The vulnerability exists in the /ramonsys/billing/index.php file where the ID parameter is not properly sanitized before being used in SQL queries. This flaw allows remote attackers to inject malicious SQL statements through manipulated input, potentially compromising the database and sensitive student information stored within the system.

Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete sensitive student data, bypass authentication mechanisms, and potentially gain unauthorized access to the underlying database server.

Affected Products

Technical Details for CVE-2026-2014

Vulnerability Analysis

This vulnerability stems from insufficient input validation in the billing module of the Student Management System. The ID parameter passed to /ramonsys/billing/index.php is directly incorporated into SQL queries without proper sanitization or the use of parameterized queries. This classic SQL injection pattern allows attackers to break out of the intended query structure and execute arbitrary SQL commands against the backend database.

The vulnerability is remotely exploitable without authentication requirements, meaning any attacker with network access to the vulnerable application can attempt exploitation. The exploit methodology has been publicly disclosed, increasing the risk of opportunistic attacks against unpatched installations.

Root Cause

The root cause of CVE-2026-2014 is improper input validation (CWE-74) and specifically SQL injection (CWE-89). The application fails to implement secure coding practices such as prepared statements, parameterized queries, or input sanitization when processing the ID parameter. User-supplied input is directly concatenated into SQL query strings, allowing attackers to inject malicious SQL syntax that alters the query's logic.

Attack Vector

The attack is network-based and requires no authentication or user interaction. An attacker can craft malicious HTTP requests to the /ramonsys/billing/index.php endpoint with a specially crafted ID parameter containing SQL injection payloads. Common attack techniques include:

Union-based SQL injection to extract data from other tables
Boolean-based blind SQL injection to infer database contents
Time-based blind SQL injection for environments where direct output is not visible
Stacked queries (if supported by the database driver) to execute multiple statements

The vulnerability allows attackers to read, modify, or delete database contents. For detailed technical information, refer to the GitHub Issue Discussion and VulDB Entry #344596.

Detection Methods for CVE-2026-2014

Indicators of Compromise

Unusual SQL error messages appearing in application logs or HTTP responses
Suspicious HTTP requests to /ramonsys/billing/index.php containing SQL keywords such as UNION, SELECT, OR 1=1, --, or '
Database query logs showing anomalous queries with unexpected syntax patterns
Unauthorized data access or modifications in student records or billing information

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block common SQL injection patterns targeting the ID parameter
Deploy intrusion detection systems (IDS) with signatures for SQL injection attack patterns
Enable detailed logging for the /ramonsys/billing/ directory and monitor for suspicious parameter values
Utilize application security monitoring tools to identify anomalous database query patterns

Monitoring Recommendations

Monitor web server access logs for requests containing SQL metacharacters in the ID parameter
Configure database audit logging to capture all queries executed against student and billing tables
Set up alerts for failed SQL query patterns that may indicate injection attempts
Review authentication logs for unauthorized access attempts following potential data extraction

How to Mitigate CVE-2026-2014

Immediate Actions Required

Restrict network access to the Student Management System to trusted IP ranges only
Implement WAF rules to filter SQL injection attempts on the /ramonsys/billing/index.php endpoint
Review database user permissions and apply principle of least privilege
Consider taking the billing module offline until a proper fix can be implemented

Patch Information

As of the last update on 2026-02-10, no official vendor patch has been released for this vulnerability. Organizations using itsourcecode Student Management System 1.0 should monitor the IT Source Code website for security updates. In the absence of an official patch, implementing the workarounds below is strongly recommended.

Workarounds

Modify the vulnerable PHP code to use prepared statements with parameterized queries for all database operations
Implement input validation to restrict the ID parameter to numeric values only using functions like intval() or filter_var()
Deploy a reverse proxy or WAF with SQL injection protection rules in front of the application
Apply network segmentation to limit exposure of the vulnerable application to untrusted networks
Consider implementing a code-level fix using PDO or MySQLi prepared statements

bash

# Example: Block suspicious requests at the web server level (Apache)
# Add to .htaccess or Apache configuration for temporary protection

<Location "/ramonsys/billing/index.php">
    RewriteEngine On
    RewriteCond %{QUERY_STRING} (union|select|insert|update|delete|drop|--|;|') [NC]
    RewriteRule .* - [F,L]
