CVE-2025-13272: School Fees Payment System SQLi Flaw

CVE-2025-13272 Overview

A SQL Injection vulnerability has been identified in Campcodes School Fees Payment Management System version 1.0. The vulnerability exists in the /manage_course.php file, where improper handling of the ID argument allows attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries without authentication, potentially leading to unauthorized data access, modification, or deletion.

Critical Impact

This SQL Injection vulnerability in an educational payment management system could expose sensitive student financial data, fee records, and administrative credentials to unauthorized access or manipulation.

Technical Details for CVE-2025-13272

Vulnerability Analysis

This vulnerability is classified as SQL Injection (CWE-89) and Injection (CWE-74). The flaw exists in the /manage_course.php file where user-supplied input via the ID parameter is not properly sanitized before being incorporated into SQL queries. An attacker can exploit this vulnerability remotely without any authentication or user interaction, making it accessible to any network-based attacker.

The vulnerability allows for low-impact compromise of confidentiality, integrity, and availability of the affected system. When exploited, attackers can read sensitive data from the database, modify existing records, or potentially cause denial of service conditions by manipulating database operations.

Root Cause

The root cause of this vulnerability is insufficient input validation and lack of parameterized queries in the /manage_course.php file. The application directly concatenates user-supplied input from the ID parameter into SQL statements without proper sanitization or the use of prepared statements. This allows malicious SQL syntax to be interpreted as part of the query structure rather than as data.

Attack Vector

The attack can be executed remotely over the network. An attacker sends a specially crafted HTTP request to the /manage_course.php endpoint with malicious SQL code injected into the ID parameter. Since no authentication is required and the exploitation does not depend on user interaction, attackers can directly target vulnerable installations from anywhere on the network.

The exploitation mechanism involves appending SQL operators and commands to the ID parameter value. Common techniques include using UNION-based injection to extract data from other tables, boolean-based blind injection to enumerate database contents, or time-based blind injection when direct data exfiltration is not possible. For technical details regarding the specific injection points and exploitation methods, refer to the GitHub CVE Issue #19.

Detection Methods for CVE-2025-13272

Indicators of Compromise

• Unusual SQL error messages in application logs referencing /manage_course.php
• HTTP requests to /manage_course.php containing SQL keywords such as UNION, SELECT, OR 1=1, or comment sequences (--, /**/)
• Database query logs showing malformed or unexpected queries originating from the course management module
• Unexpected data access patterns or bulk data retrieval from fee-related database tables

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to /manage_course.php
• Monitor web server access logs for requests containing SQL injection signatures targeting the ID parameter
• Deploy database activity monitoring to detect anomalous query patterns or unauthorized data access
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Enable detailed logging for the /manage_course.php endpoint to capture all incoming request parameters
• Configure alerting for database errors that may indicate failed SQL injection attempts
• Implement real-time monitoring of HTTP requests for SQL metacharacters in the ID parameter
• Review database audit logs regularly for signs of data exfiltration or unauthorized modifications

How to Mitigate CVE-2025-13272

Immediate Actions Required

• Restrict network access to the School Fees Payment Management System to trusted IP addresses only
• Implement input validation and sanitization for the ID parameter in /manage_course.php
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules in front of the application
• Consider temporarily disabling the affected functionality until a proper fix is implemented

Patch Information

At the time of this publication, no official patch has been released by Campcodes for this vulnerability. Organizations using this software should contact Campcodes directly for remediation guidance or consider implementing the workarounds below. Monitor the CampCodes Security Resource page for security updates. Additional technical details are available through the VulDB #332607 entry.

Workarounds

• Implement parameterized queries or prepared statements for all database interactions in /manage_course.php
• Apply strict input validation to ensure the ID parameter contains only expected numeric values
• Use a Web Application Firewall to filter malicious SQL injection payloads before they reach the application
• Implement least privilege database access so the application database user has only necessary permissions

# Example: Restrict access using .htaccess (Apache)
<Files "manage_course.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
</Files>
