CVE-2025-4507: Campcodes Food Ordering System SQLi Flaw

CVE-2025-4507 Overview

A critical SQL injection vulnerability has been identified in Campcodes Online Food Ordering System version 1.0. The vulnerability exists in the /routers/add-item.php file, where improper handling of the price argument allows attackers to inject malicious SQL queries. This flaw can be exploited remotely without authentication, potentially leading to unauthorized database access, data manipulation, or complete system compromise.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to manipulate database queries, potentially extracting sensitive customer data, modifying order information, or gaining unauthorized access to the underlying database server.

Affected Products

• Campcodes Online Food Ordering System 1.0
• Web applications using the vulnerable /routers/add-item.php endpoint
• Systems with network-accessible instances of the affected software

Technical Details for CVE-2025-4507

Vulnerability Analysis

This SQL injection vulnerability stems from insufficient input validation and sanitization in the add-item.php router component. When processing item additions, the application directly incorporates user-supplied data from the price argument into SQL queries without proper parameterization or escaping. This allows an attacker to craft malicious input that breaks out of the intended query context and executes arbitrary SQL commands against the backend database.

The vulnerability is network-accessible, meaning any attacker with HTTP access to the application can attempt exploitation. No authentication is required to reach the vulnerable endpoint, significantly expanding the attack surface. The exploit has been publicly disclosed, increasing the risk of active exploitation in the wild.

Root Cause

The root cause of CVE-2025-4507 is the failure to implement prepared statements or parameterized queries when handling user input in the price parameter. The application appears to construct SQL queries through string concatenation, incorporating untrusted user input directly into the query string. This violates secure coding practices and enables injection attacks. The lack of input validation, type checking, or output encoding compounds the issue, allowing various SQL injection payloads to succeed.

Attack Vector

The attack vector for this vulnerability is network-based, requiring no user interaction or special privileges. An attacker can craft HTTP requests to the /routers/add-item.php endpoint with malicious SQL payloads embedded in the price parameter. Common exploitation techniques include:

• Union-based injection: Appending UNION SELECT statements to extract data from other tables
• Boolean-based blind injection: Using conditional statements to infer database structure and content
• Time-based blind injection: Employing database sleep functions to extract information through timing analysis
• Error-based injection: Triggering verbose database errors to leak schema information

The vulnerability allows attackers to potentially read sensitive data such as customer information, payment details, and order history. In severe cases, attackers may be able to modify or delete data, escalate privileges within the database, or even execute system commands depending on the database configuration and privileges.

Detection Methods for CVE-2025-4507

Indicators of Compromise

• Unusual SQL syntax patterns in web server logs targeting /routers/add-item.php
• Unexpected database queries containing UNION SELECT, information_schema, or sleep() functions
• Anomalous price parameter values containing special characters like single quotes, semicolons, or SQL keywords
• Database errors or exceptions logged from the add-item functionality

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the price parameter
• Monitor application logs for requests to /routers/add-item.php with suspicious parameter values
• Deploy intrusion detection systems (IDS) with signatures for common SQL injection payloads
• Enable database query logging and alert on queries with unusual structure or syntax

Monitoring Recommendations

• Review access logs for the /routers/add-item.php endpoint for anomalous request patterns
• Set up real-time alerting for database errors originating from the item addition functionality
• Implement rate limiting on the affected endpoint to slow potential automated exploitation attempts
• Monitor database performance metrics for unexpected query patterns or resource consumption

How to Mitigate CVE-2025-4507

Immediate Actions Required

• Restrict network access to the Campcodes Online Food Ordering System to trusted IP addresses only
• Implement a Web Application Firewall (WAF) with SQL injection protection rules
• Consider temporarily disabling the /routers/add-item.php functionality until a patch is available
• Review and audit database access privileges to minimize potential impact of successful exploitation

Patch Information

As of the last NVD update on 2025-05-13, no official vendor patch has been publicly announced for this vulnerability. Organizations using Campcodes Online Food Ordering System should monitor the CampCodes website for security updates. Additional technical details and community discussion can be found at the GitHub Issue Discussion and VulDB entry #308223.

Workarounds

• Apply input validation to strictly enforce numeric values for the price parameter before processing
• Implement prepared statements or parameterized queries in the add-item.php file to prevent SQL injection
• Deploy application-layer filtering to sanitize special characters and SQL keywords from user input
• Place the application behind a reverse proxy with request inspection capabilities

# Example: Apache mod_rewrite rule to block suspicious price parameter values
# Add to .htaccess or Apache configuration
RewriteEngine On
RewriteCond %{QUERY_STRING} (union|select|insert|delete|drop|--|;|'|") [NC]
RewriteRule ^routers/add-item\.php - [F,L]
