CVE-2026-2011: School Management System SQL Injection Flaw

CVE-2026-2011 Overview

A SQL injection vulnerability has been identified in itsourcecode Student Management System version 1.0. The vulnerability exists in the /ramonsys/enrollment/controller.php file, where the ID parameter is not properly sanitized before being used in database queries. This flaw allows remote attackers to manipulate SQL queries and potentially gain unauthorized access to sensitive data, modify database contents, or disrupt database operations.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive student records, manipulate enrollment data, or compromise the underlying database without authentication.

Technical Details for CVE-2026-2011

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) stems from improper neutralization of special elements used in SQL commands. The vulnerable endpoint at /ramonsys/enrollment/controller.php accepts user-supplied input through the ID parameter and directly incorporates it into SQL queries without proper validation or parameterization. This is also classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component).

The vulnerability is exploitable remotely over the network with no authentication required. An attacker can craft malicious requests containing SQL syntax that will be interpreted by the database engine, potentially leading to data exfiltration, unauthorized data modification, or denial of service conditions.

Root Cause

The root cause of this vulnerability is the failure to implement proper input validation and parameterized queries in the enrollment controller. The ID parameter from user input is concatenated directly into SQL statements rather than being passed through prepared statements with bound parameters. This classic SQL injection pattern allows attackers to break out of the intended query structure and inject arbitrary SQL commands.

Attack Vector

The attack vector is network-based, requiring no user interaction or prior authentication. An attacker can exploit this vulnerability by sending specially crafted HTTP requests to the /ramonsys/enrollment/controller.php endpoint with malicious SQL payloads in the ID parameter.

The exploitation technique involves injecting SQL metacharacters and additional SQL clauses into the ID parameter. For example, an attacker could append UNION-based queries to extract data from other tables, use boolean-based blind injection to enumerate database contents character by character, or employ time-based techniques if other methods fail. The exploit has been publicly disclosed, increasing the risk of widespread exploitation. For detailed technical information, refer to the GitHub Issue on CVE Discoveries.

Detection Methods for CVE-2026-2011

Indicators of Compromise

• Unusual SQL syntax patterns in web server access logs for /ramonsys/enrollment/controller.php
• Unexpected database query errors or timeouts originating from the enrollment controller
• Anomalous data access patterns in database audit logs showing bulk data retrieval or unauthorized table access
• Web application firewall alerts for SQL injection attack signatures targeting the ID parameter

Detection Strategies

• Implement web application firewall (WAF) rules to detect and block SQL injection attempts targeting the ID parameter
• Enable detailed logging on web servers and monitor for requests containing SQL keywords such as UNION, SELECT, DROP, or comment sequences like -- or /*
• Deploy database activity monitoring to detect unusual query patterns or unauthorized data access
• Use SentinelOne Singularity Platform to detect post-exploitation behaviors following successful SQL injection attacks

Monitoring Recommendations

• Configure real-time alerting for any access to /ramonsys/enrollment/controller.php containing suspicious characters such as single quotes, semicolons, or SQL keywords
• Monitor database server performance metrics for unusual spikes that may indicate data exfiltration attempts
• Review authentication logs for any unauthorized administrative access that may result from privilege escalation through SQL injection

How to Mitigate CVE-2026-2011

Immediate Actions Required

• Restrict access to the /ramonsys/enrollment/controller.php endpoint using network-level controls until a patch is available
• Implement web application firewall rules to filter malicious SQL injection payloads
• Review and audit database permissions to minimize the impact of potential exploitation
• Consider taking the affected application offline if it contains sensitive student data and cannot be adequately protected

Patch Information

No official vendor patch has been released at this time. The vendor itsourcecode has been notified of this vulnerability. Administrators should monitor the IT Source Code Resource for security updates. Additional vulnerability details are available at VulDB #344593.

Workarounds

• Implement input validation on the ID parameter to accept only numeric values
• Deploy a web application firewall (WAF) with SQL injection detection rules in blocking mode
• Use database stored procedures with parameterized inputs as an intermediate layer
• Restrict database user privileges for the web application to minimum required permissions (principle of least privilege)

# Example .htaccess rules to restrict access to vulnerable endpoint
<Files "controller.php">
    # Allow only from trusted internal networks
    Require ip 192.168.1.0/24
    Require ip 10.0.0.0/8
</Files>

# Alternative: Block requests with common SQL injection patterns
RewriteEngine On
RewriteCond %{QUERY_STRING} (union|select|insert|update|delete|drop|script) [NC]
RewriteRule ^ramonsys/enrollment/controller\.php$ - [F,L]
