CVE-2026-7229: Coaching Management System SQLi Vulnerability

CVE-2026-7229 Overview

A SQL Injection vulnerability has been identified in code-projects Coaching Management System version 1.0. The vulnerability exists in the /cims/modules/admin/reply.php file within the POST Handler component. By manipulating the complaintreply argument, an authenticated attacker can inject malicious SQL queries, potentially leading to unauthorized data access, modification, or deletion. The vulnerability can be exploited remotely and proof-of-concept code has been publicly disclosed.

Critical Impact
Authenticated attackers can exploit this SQL Injection vulnerability to manipulate database queries through the complaintreply parameter, potentially compromising the confidentiality, integrity, and availability of backend data.

Technical Details for CVE-2026-7229

Vulnerability Analysis

This vulnerability falls under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly known as injection. The flaw resides in the complaint reply functionality of the Coaching Management System's administrative module.

The vulnerable endpoint at /cims/modules/admin/reply.php fails to properly sanitize user-supplied input in the complaintreply parameter before incorporating it into SQL queries. When an authenticated administrator submits a reply to a complaint through the POST request handler, the application directly concatenates the input into database operations without adequate parameterization or escaping.

This allows an attacker with valid administrative credentials to craft malicious input containing SQL syntax that modifies the intended query logic. The vulnerability can be exploited to extract sensitive information from the database, modify or delete records, or potentially escalate access depending on database permissions.

Root Cause

The root cause of this vulnerability is insufficient input validation and lack of parameterized queries in the reply.php POST handler. The complaintreply argument is directly interpolated into SQL statements without proper sanitization, allowing SQL metacharacters to break out of the intended query context and execute arbitrary SQL commands.

Attack Vector

The attack is network-based and requires authenticated access to the administrative interface. An attacker must first obtain valid credentials for the Coaching Management System admin panel. Once authenticated, they can submit a crafted POST request to the /cims/modules/admin/reply.php endpoint with a malicious payload in the complaintreply parameter.

The exploitation process involves sending SQL injection payloads through the complaint reply form. The injected SQL commands are then executed by the database server with the privileges of the application's database user. Technical details and proof-of-concept code are available in the GitHub Exploit Repository.

Detection Methods for CVE-2026-7229

Indicators of Compromise

Unusual or malformed requests to /cims/modules/admin/reply.php containing SQL syntax characters such as single quotes, double dashes, or UNION keywords
Database error messages appearing in application logs or HTTP responses indicating SQL syntax errors
Unexpected database queries or data modifications originating from the complaint reply functionality
Authentication followed by immediate suspicious POST requests to the vulnerable endpoint

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in POST parameters targeting /cims/modules/admin/reply.php
Configure database auditing to log and alert on unusual query patterns, especially those containing UNION, SELECT, or information_schema references
Deploy intrusion detection signatures that monitor for SQL injection attack patterns in HTTP POST bodies
Review web server access logs for repeated requests to the vulnerable endpoint with varying payloads

Monitoring Recommendations

Enable detailed logging for all administrative actions within the Coaching Management System
Monitor database query logs for anomalous patterns or unauthorized data access attempts
Set up alerts for multiple failed or suspicious requests to administrative endpoints
Implement real-time monitoring of the /cims/modules/admin/ directory for unusual activity patterns

How to Mitigate CVE-2026-7229

Immediate Actions Required

Restrict access to the Coaching Management System administrative interface to trusted IP addresses only
Implement additional authentication controls such as multi-factor authentication for admin accounts
Deploy a Web Application Firewall with SQL injection protection rules in front of the application
Review and audit all administrative account credentials and remove any unused or suspicious accounts

Patch Information

As of the last update on 2026-04-29, no official patch has been released by code-projects for this vulnerability. Organizations using the Coaching Management System should monitor the Code Projects Resource page for security updates and apply patches immediately when available. Additional vulnerability details can be found at VulDB Vulnerability #359830.

Workarounds

Implement input validation on the complaintreply parameter to reject any input containing SQL metacharacters such as single quotes, semicolons, or SQL keywords
Modify the application code to use prepared statements with parameterized queries instead of string concatenation for database operations
Consider temporarily disabling the complaint reply functionality until a proper fix can be implemented
Apply network-level access controls to limit administrative interface access to internal networks only
