CVE-2026-4472: Online Frozen Foods Ordering System SQLi

CVE-2026-4472 Overview

A SQL Injection vulnerability has been identified in itsourcecode Online Frozen Foods Ordering System version 1.0. This vulnerability affects the file /admin/admin_edit_supplier.php where improper handling of the Supplier_Name parameter allows for SQL injection attacks. The vulnerability can be exploited remotely by authenticated users with low privileges, potentially compromising the confidentiality, integrity, and availability of the underlying database.

Critical Impact

Attackers can execute arbitrary SQL queries through the vulnerable Supplier_Name parameter, potentially leading to unauthorized data access, data manipulation, or database compromise.

Technical Details for CVE-2026-4472

Vulnerability Analysis

This SQL Injection vulnerability exists in the admin supplier editing functionality of the Online Frozen Foods Ordering System. The application fails to properly sanitize or parameterize user input in the Supplier_Name argument before incorporating it into SQL queries. This allows an authenticated attacker with low-level privileges to inject malicious SQL statements through the web interface.

The vulnerability is classified under both CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component). When exploited, attackers can potentially read sensitive database contents, modify or delete data, or in some configurations, execute system commands on the database server.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and parameterized queries in the /admin/admin_edit_supplier.php file. The Supplier_Name parameter is directly concatenated into SQL queries without sanitization, allowing special SQL characters and commands to be interpreted by the database engine.

Attack Vector

The attack can be initiated remotely over the network. An attacker with low-privilege authenticated access to the admin panel can manipulate the Supplier_Name field when editing supplier information. By inserting specially crafted SQL syntax into this field, the attacker can alter the intended SQL query logic to extract data, bypass authentication checks, or modify database records.

The exploitation technique involves submitting malicious input through the supplier edit form, where the unsanitized data is passed directly to the database query. The exploit has been publicly disclosed, increasing the risk of opportunistic attacks against unpatched systems.

Detection Methods for CVE-2026-4472

Indicators of Compromise

• Unusual SQL error messages appearing in application logs related to /admin/admin_edit_supplier.php
• Database query logs showing malformed or suspicious queries containing SQL keywords like UNION, SELECT, DROP, or comment sequences (--, /*)
• Unexpected database modifications or unauthorized data access patterns
• Web server access logs showing repeated POST requests to /admin/admin_edit_supplier.php with abnormal payload sizes

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to /admin/admin_edit_supplier.php
• Monitor application logs for SQL syntax errors that may indicate injection attempts
• Deploy database activity monitoring to identify anomalous query patterns or unauthorized data access
• Use intrusion detection systems (IDS) with SQL injection signature detection capabilities

Monitoring Recommendations

• Enable verbose logging for the web application and database server to capture detailed query information
• Set up alerts for repeated failed database queries or authentication anomalies
• Monitor for unusual outbound network traffic from the database server that could indicate data exfiltration
• Regularly review access logs for the admin panel to identify suspicious authentication patterns

How to Mitigate CVE-2026-4472

Immediate Actions Required

• Restrict access to the admin panel (/admin/) to trusted IP addresses only using firewall rules or web server configuration
• Implement additional authentication controls for the supplier management functionality
• Deploy a Web Application Firewall (WAF) with SQL injection protection enabled
• Consider disabling the supplier editing functionality until a patch can be applied

Patch Information

No official vendor patch has been released for this vulnerability at the time of publication. Users are advised to monitor the GitHub Issue Tracker for updates and community-developed fixes. Additional information about the vulnerability can be found at VulDB #351762 and the IT Source Code Resource page.

Workarounds

• Manually implement input validation and parameterized queries in the affected /admin/admin_edit_supplier.php file
• Use prepared statements with bound parameters for all database queries involving user input
• Restrict database user privileges to the minimum necessary for application functionality
• Implement a Web Application Firewall to filter malicious input before it reaches the application

# Configuration example - Apache .htaccess to restrict admin access
<Directory "/var/www/html/admin">
    Order Deny,Allow
    Deny from all
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Directory>
