CVE-2026-4469: Online Frozen Foods Ordering System SQLi

CVE-2026-4469 Overview

A SQL injection vulnerability has been identified in the itsourcecode Online Frozen Foods Ordering System version 1.0. This security flaw affects the file /admin/admin_edit_menu_action.php, where improper handling of the product_name argument allows attackers to inject malicious SQL commands. The vulnerability can be exploited remotely, and public exploit information is available, increasing the risk of active exploitation.

Critical Impact

Remote attackers with administrative privileges can exploit this SQL injection vulnerability to manipulate database queries, potentially leading to unauthorized data access, data modification, or compromise of the underlying database system.

Technical Details for CVE-2026-4469

Vulnerability Analysis

This SQL injection vulnerability exists in the administrative menu editing functionality of the Online Frozen Foods Ordering System. The affected component, /admin/admin_edit_menu_action.php, fails to properly sanitize or parameterize user-supplied input in the product_name argument before incorporating it into SQL queries.

The vulnerability is classified under CWE-89 (Improper Neutralization of Special Elements used in an SQL Command) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). These classifications indicate that the application does not adequately escape or filter user input before passing it to the database engine.

Since the vulnerability resides in an administrative interface, exploitation requires authenticated access with administrative privileges. However, once an attacker gains admin access—whether through credential theft, brute force, or other means—they can leverage this SQL injection to escalate their impact significantly.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and the absence of parameterized queries (prepared statements) in the admin_edit_menu_action.php file. The product_name parameter is directly concatenated into SQL statements without sanitization, allowing attackers to break out of the intended query structure and inject arbitrary SQL commands.

This is a classic example of improper input handling in PHP web applications where user-controlled data flows directly into database queries. The application likely uses direct string interpolation or concatenation when building SQL queries rather than using PDO prepared statements or mysqli parameterized queries.

Attack Vector

The attack is network-based and targets the administrative panel of the Online Frozen Foods Ordering System. An attacker with valid administrative credentials can access the menu editing functionality and inject SQL payloads through the product_name field.

The SQL injection attack can be performed by crafting malicious input that includes SQL metacharacters and commands. For example, an attacker could submit a product name containing single quotes and SQL statements to manipulate the query logic. This could enable various attacks including extracting sensitive data from other database tables, modifying or deleting records, or potentially executing database administrative operations depending on the database permissions configured for the application.

Detection Methods for CVE-2026-4469

Indicators of Compromise

• Unusual or malformed entries in the product_name field containing SQL syntax such as single quotes, semicolons, UNION keywords, or comment characters (--, /*)
• Database error logs showing SQL syntax errors or unexpected query failures originating from /admin/admin_edit_menu_action.php
• Audit logs revealing abnormal administrative activity patterns, especially repeated menu edit operations with suspicious payloads

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect common SQL injection patterns in HTTP POST requests to administrative endpoints
• Enable database query logging and monitor for anomalous SQL statements containing stacked queries or UNION-based injection attempts
• Deploy application-level logging to capture all input to the product_name parameter and alert on suspicious patterns

Monitoring Recommendations

• Monitor access logs for repeated or automated requests to /admin/admin_edit_menu_action.php from single IP addresses or unusual geographic locations
• Set up alerts for database account privilege escalation attempts or queries accessing system tables
• Review administrative user activity logs for abnormal session behavior or access outside normal operational hours

How to Mitigate CVE-2026-4469

Immediate Actions Required

• Restrict access to the administrative panel by implementing IP whitelisting or VPN requirements
• Temporarily disable the menu editing functionality if it is not critical to operations
• Audit all administrative user accounts and reset credentials, removing any suspicious or unnecessary accounts
• Deploy a WAF with SQL injection protection rules in front of the application

Patch Information

As of the last update on 2026-03-23, no official vendor patch has been released for this vulnerability. The software is distributed through IT Source Code, and users should monitor for any security updates or patches. Given that this is an open-source educational project, users may need to implement their own fixes or consider alternative solutions.

For additional vulnerability information and tracking, see VulDB #351759.

Workarounds

• Implement input validation by modifying the admin_edit_menu_action.php file to use prepared statements with parameterized queries for all database operations
• Add server-side input sanitization to strip or escape SQL metacharacters from the product_name and all other user-controlled parameters
• Consider deploying the application behind a reverse proxy with SQL injection filtering capabilities such as ModSecurity with OWASP Core Rule Set

# Example: Restrict admin panel access via Apache .htaccess
# Add to /admin/.htaccess
<Files "admin_edit_menu_action.php">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Files>
