CVE-2025-4549: Campcodes Online Food Ordering SQLi Flaw

CVE-2025-4549 Overview

A critical SQL injection vulnerability has been identified in Campcodes Online Food Ordering System version 1.0. This vulnerability exists in the /routers/register-router.php file where the Name argument is improperly handled, allowing attackers to inject malicious SQL commands. The vulnerability can be exploited remotely without authentication, potentially compromising the confidentiality, integrity, and availability of the underlying database and application.

Critical Impact
Remote attackers can exploit improper input validation in the registration functionality to execute arbitrary SQL commands, potentially leading to unauthorized data access, data manipulation, or complete database compromise.

Technical Details for CVE-2025-4549

Vulnerability Analysis

This SQL injection vulnerability stems from inadequate input validation and sanitization in the user registration component of the Campcodes Online Food Ordering System. The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly referred to as "Injection."

The vulnerable endpoint /routers/register-router.php accepts user-supplied input through the Name parameter without proper sanitization before incorporating it into SQL queries. This allows an attacker to craft malicious input that escapes the intended SQL context and executes arbitrary database commands.

The attack can be initiated remotely over the network without requiring any user interaction or prior authentication, making it particularly dangerous for internet-facing deployments of this food ordering system.

Root Cause

The root cause of this vulnerability is the failure to properly sanitize and validate user input in the Name parameter before using it in SQL queries. The application likely uses direct string concatenation or inadequate parameterization when constructing SQL statements, allowing special SQL characters and commands to be interpreted as part of the query structure rather than as literal data values.

Attack Vector

The attack is network-based and can be performed remotely by any unauthenticated attacker with network access to the vulnerable application. The attacker submits a specially crafted registration request containing SQL injection payloads in the Name field. When the application processes this input, the malicious SQL commands are executed against the backend database.

Successful exploitation could allow an attacker to:

Extract sensitive data from the database including user credentials, order information, and payment details
Modify or delete database records
Bypass authentication mechanisms
Potentially execute operating system commands if database permissions allow

The vulnerability has been publicly disclosed and exploit details may be available, as indicated in the GitHub CVE Issue Discussion.

Detection Methods for CVE-2025-4549

Indicators of Compromise

Unusual SQL error messages in application logs originating from /routers/register-router.php
Registration requests containing SQL syntax characters such as single quotes, semicolons, or SQL keywords (UNION, SELECT, DROP, etc.) in the Name field
Anomalous database query patterns or unexpected data access attempts
Multiple failed or malformed registration attempts from the same source IP

Detection Strategies

Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in HTTP POST requests to /routers/register-router.php
Implement database activity monitoring to alert on unusual query patterns or suspicious statements
Enable detailed logging for the registration endpoint and monitor for SQL injection signatures
Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

Monitor application logs for HTTP 500 errors or database exceptions related to the registration functionality
Track and alert on registration attempts with unusually long or formatted Name field values
Set up real-time alerts for database queries containing UNION, SELECT, or other SQL keywords originating from application user input
Review access logs for repeated requests to /routers/register-router.php from single IP addresses

How to Mitigate CVE-2025-4549

Immediate Actions Required

Remove or disable the Campcodes Online Food Ordering System from production if no patch is available
Implement input validation at the web server or WAF level to block SQL injection attempts targeting the Name parameter
Review and restrict database user permissions to minimize potential impact of SQL injection
Enable application-level logging and monitoring for the affected endpoint

Patch Information

At the time of publication, no official patch or vendor advisory has been released by Campcodes for this vulnerability. Users should monitor the Camp Codes website for security updates and patches. Additional technical information is available through VulDB Resource #308296.

Workarounds

Implement prepared statements with parameterized queries if you have access to modify the source code
Deploy a Web Application Firewall (WAF) configured to filter SQL injection attacks targeting the vulnerable endpoint
Restrict network access to the application to trusted IP ranges only
Consider taking the affected system offline until a proper fix is available, especially for internet-facing deployments
