CVE-2026-4470: Frozen Foods Ordering System SQLi Flaw

CVE-2026-4470 Overview

A SQL injection vulnerability has been discovered in the itsourcecode Online Frozen Foods Ordering System version 1.0. This security flaw affects the file /admin/admin_edit_menu.php, where manipulation of the product_name argument allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely by authenticated administrators, potentially leading to unauthorized data access, modification, or system compromise.

Critical Impact

Authenticated attackers with administrative privileges can execute arbitrary SQL commands against the underlying database, potentially extracting sensitive customer data, manipulating order records, or escalating access within the application.

Technical Details for CVE-2026-4470

Vulnerability Analysis

This vulnerability is classified as SQL Injection (CWE-89) and falls under the broader category of Injection vulnerabilities (CWE-74). The affected endpoint /admin/admin_edit_menu.php fails to properly sanitize user input passed through the product_name parameter before incorporating it into SQL queries. This allows an attacker with administrative access to craft malicious input that alters the intended SQL query logic.

The attack requires network access and administrative privileges within the application. Despite the privilege requirement, the vulnerability is significant because it can lead to unauthorized disclosure of confidential information stored in the database, modification of existing records, and potential lateral movement if database credentials are reused elsewhere.

Root Cause

The root cause of this vulnerability is improper input validation and the absence of parameterized queries or prepared statements in the admin_edit_menu.php file. When processing the product_name argument, the application directly concatenates user-supplied input into SQL statements without adequate sanitization or escaping. This allows special characters and SQL syntax to be interpreted as part of the query rather than as literal string values.

Attack Vector

The attack vector is network-based, requiring the attacker to authenticate with administrative credentials. Once authenticated, an attacker can submit crafted input to the product_name parameter when editing menu items. The malicious payload bypasses input validation and executes within the context of the database query.

Typical exploitation involves injecting SQL payloads such as UNION-based queries to extract data from other tables, time-based blind injection techniques to enumerate database contents, or stacked queries to modify or delete records. The exploit methodology has been publicly disclosed, increasing the risk of opportunistic attacks.

Detection Methods for CVE-2026-4470

Indicators of Compromise

• Unusual or malformed values in the product_name field containing SQL keywords such as UNION, SELECT, OR, AND, or comment characters (--, /*)
• Database query logs showing unexpected queries or error messages related to SQL syntax
• Unauthorized changes to product menu data or pricing information
• Evidence of data exfiltration through abnormal network traffic from the database server

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns targeting the /admin/admin_edit_menu.php endpoint
• Monitor application logs for HTTP POST requests to admin_edit_menu.php containing suspicious characters in the product_name parameter
• Enable database audit logging to track all queries executed against the application database
• Deploy SentinelOne Singularity Platform to detect anomalous process behavior and unauthorized database access patterns

Monitoring Recommendations

• Configure alerting for failed SQL queries or syntax errors originating from the application
• Establish baseline patterns for administrative actions and alert on deviations
• Monitor for bulk data exports or unusual SELECT query patterns that may indicate data exfiltration
• Review access logs for repeated attempts to access the vulnerable endpoint from unusual IP addresses

How to Mitigate CVE-2026-4470

Immediate Actions Required

• Restrict access to the /admin/admin_edit_menu.php endpoint to trusted IP addresses only until a patch is available
• Implement additional input validation at the application level to reject SQL metacharacters in the product_name parameter
• Review and audit all administrative accounts for unauthorized access
• Consider temporarily disabling the menu edit functionality if business operations permit

Patch Information

As of the last update on 2026-03-23, no official vendor patch has been released. The vulnerability has been documented in a GitHub Issue Discussion and tracked by VulDB #351760. Organizations using this software should monitor IT Source Code for security updates and apply patches immediately when available.

Workarounds

• Implement prepared statements or parameterized queries by modifying the PHP source code to use PDO or MySQLi with bound parameters
• Deploy a Web Application Firewall (WAF) with rules configured to block SQL injection attempts
• Apply input validation filters to sanitize the product_name parameter, allowing only alphanumeric characters and common punctuation
• Limit database user privileges for the application to only the minimum required operations (principle of least privilege)

# Configuration example - Apache .htaccess to restrict admin access
<Files "admin_edit_menu.php">
    Order Deny,Allow
    Deny from all
    # Allow only trusted IP addresses
    Allow from 192.168.1.0/24
    Allow from 10.0.0.0/8
</Files>
