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

CVE-2026-4470 Overview

CVE-2026-4470 is a SQL injection vulnerability in itsourcecode Online Frozen Foods Ordering System 1.0. The flaw resides in the /admin/admin_edit_menu.php script, where the product_name parameter is concatenated into a SQL query without proper sanitization. An authenticated remote attacker can manipulate this parameter to inject arbitrary SQL statements. The exploit code is publicly available, increasing the likelihood of opportunistic attacks against exposed installations.

Critical Impact

Authenticated attackers can inject SQL statements through the product_name argument, potentially reading, modifying, or deleting administrative data within the ordering system database.

Affected Products

• Adonesevangelista Online Frozen Foods Ordering System 1.0
• Component: /admin/admin_edit_menu.php

Technical Details for CVE-2026-4470

Vulnerability Analysis

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). The administrative menu editor in admin_edit_menu.php accepts the product_name request parameter and passes it directly into a backend SQL query. Because the application does not parameterize statements or validate input, attacker-controlled SQL fragments execute against the database. The attack requires high privileges, which limits exposure to users who already hold administrative access or have compromised an admin session.

Root Cause

The root cause is unsanitized concatenation of HTTP request data into SQL statements within the menu editing routine. The application does not use prepared statements, parameter binding, or input validation. Any user able to reach the admin edit menu endpoint can alter the structure of the executed query.

Attack Vector

The attack is delivered over the network against the administrative interface. An attacker submits a crafted HTTP request containing SQL payload syntax in the product_name field. The injected fragment is executed inside the backend query, enabling data extraction, modification of menu records, or pivoting through stacked queries depending on the database driver in use.

Detection Methods for CVE-2026-4470

Indicators of Compromise

• HTTP POST or GET requests to /admin/admin_edit_menu.php containing SQL meta-characters such as single quotes, UNION, SELECT, --, or ; in the product_name parameter.
• Unexpected modifications, insertions, or deletions in the menu and product tables of the ordering system database.
• Web server access logs showing repeated requests to admin_edit_menu.php from a single source within a short time window.

Detection Strategies

• Deploy web application firewall signatures that inspect product_name values for SQL injection patterns on the admin endpoint.
• Enable database query logging and alert on syntactically anomalous queries originating from the menu editor module.
• Correlate administrative authentication events with subsequent edits to admin_edit_menu.php to identify abuse of compromised admin credentials.

Monitoring Recommendations

• Monitor the /admin/ directory for unauthorized file uploads or modifications that may follow successful SQL injection.
• Track outbound database connections and large result sets returned to the application from menu-related queries.
• Review admin account session activity and source IP addresses for unusual geolocation or off-hours access.

How to Mitigate CVE-2026-4470

Immediate Actions Required

• Restrict access to the /admin/ path through network-level controls or IP allow-listing until a fix is applied.
• Rotate all administrative credentials and review admin user accounts for unauthorized additions.
• Audit the ordering system database for unexpected changes in product, menu, and user tables.

Patch Information

No official vendor patch is referenced in the available advisories. Public tracking is maintained through the GitHub Issue Tracker and VulDB #351760. Administrators should monitor the ItSourceCode Homepage for vendor updates.

Workarounds

• Apply a virtual patch using a WAF rule that blocks SQL meta-characters in the product_name parameter of admin_edit_menu.php.
• Modify the vulnerable PHP source to use parameterized queries with PDO or mysqli prepared statements instead of string concatenation.
• Enforce least-privilege database accounts so that the web application user cannot execute schema changes or read sensitive system tables.
