CVE-2025-4506: Campcodes Food Ordering System SQL Injection

CVE-2025-4506 Overview

A critical SQL injection vulnerability has been identified in Campcodes Online Food Ordering System version 1.0. The vulnerability exists in the /routers/menu-router.php file, where improper handling of the 1_price parameter allows attackers to inject malicious SQL commands. This flaw can be exploited remotely without authentication, potentially allowing attackers to extract sensitive data, modify database contents, or compromise the underlying server.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to access, modify, or delete database contents, potentially compromising customer information, order data, and administrative credentials in the food ordering platform.

Affected Products

• Campcodes Online Food Ordering System version 1.0
• Web applications using the vulnerable /routers/menu-router.php endpoint

Technical Details for CVE-2025-4506

Vulnerability Analysis

This SQL injection vulnerability in Campcodes Online Food Ordering System stems from inadequate input validation in the menu routing functionality. The 1_price parameter in /routers/menu-router.php accepts user-controlled input that is directly incorporated into SQL queries without proper sanitization or parameterization.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where untrusted data is sent to an interpreter as part of a command or query. In this case, an attacker can craft malicious input containing SQL syntax that alters the intended query logic.

The exploit has been publicly disclosed, increasing the risk of active exploitation against unpatched systems. Organizations running this food ordering platform should treat remediation as a priority.

Root Cause

The root cause of CVE-2025-4506 is the failure to implement proper input validation and parameterized queries in the menu-router.php file. The 1_price parameter is directly concatenated into SQL statements without escaping special characters or using prepared statements. This allows metacharacters such as single quotes, semicolons, and SQL keywords to be interpreted as executable code rather than literal data.

Attack Vector

The attack is network-based and requires no authentication or user interaction. An attacker can send specially crafted HTTP requests to the vulnerable endpoint, manipulating the 1_price parameter to inject SQL commands. The exploitation flow typically involves:

1. Identifying the vulnerable parameter in the menu routing endpoint
2. Testing for SQL injection by injecting SQL metacharacters
3. Extracting database schema information through UNION-based or error-based techniques
4. Exfiltrating sensitive data such as customer records, payment information, or administrator credentials

Due to the nature of food ordering systems, successful exploitation could expose personally identifiable information (PII), addresses, order history, and potentially payment data stored in the database. For detailed technical information, refer to the GitHub Issue Tracker and VulDB advisory.

Detection Methods for CVE-2025-4506

Indicators of Compromise

• Unusual SQL error messages in web server logs related to /routers/menu-router.php
• HTTP requests containing SQL metacharacters (single quotes, semicolons, UNION, SELECT) in the 1_price parameter
• Database query logs showing unexpected SELECT, UNION, or administrative commands
• Abnormal outbound data transfers from the database server

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns targeting the 1_price parameter
• Monitor HTTP access logs for requests to /routers/menu-router.php containing suspicious payloads
• Enable database query logging and alert on queries containing UNION statements or subqueries
• Deploy application-layer intrusion detection to identify SQL injection attack signatures

Monitoring Recommendations

• Enable verbose logging on the web application server for the /routers/ directory
• Configure database audit logging to capture all queries executed against sensitive tables
• Set up real-time alerting for SQL syntax errors or injection attempts in application logs
• Review web server access logs regularly for reconnaissance patterns targeting the vulnerable endpoint

How to Mitigate CVE-2025-4506

Immediate Actions Required

• Disable or restrict access to the /routers/menu-router.php endpoint until a patch is applied
• Implement input validation to sanitize the 1_price parameter and reject non-numeric values
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules
• Review database logs for evidence of prior exploitation attempts
• Consider taking the affected application offline if sensitive data is at risk

Patch Information

At the time of publication, no official vendor patch has been released for this vulnerability. Organizations should monitor the Campcodes website for security updates. In the absence of an official patch, implement the workarounds below and consider replacing the vulnerable component with secure alternatives.

For additional technical details and vulnerability tracking, refer to the VulDB advisory and the GitHub issue report.

Workarounds

• Implement server-side input validation to ensure 1_price only accepts numeric values
• Use parameterized queries or prepared statements in the menu-router.php file
• Apply the principle of least privilege to the database user account used by the application
• Restrict network access to the application to trusted IP ranges where feasible

# Example: Block access to vulnerable endpoint via Apache .htaccess
<Files "menu-router.php">
    Order Deny,Allow
    Deny from all
    # Allow only from trusted admin IPs
    Allow from 192.168.1.0/24
</Files>
