CVE-2025-4490: Campcodes Food Ordering System SQLi Flaw

CVE-2025-4490 Overview

A critical SQL injection vulnerability has been identified in Campcodes Online Food Ordering System version 1.0. The vulnerability exists in the /view-ticket-admin.php file, where the ID parameter is susceptible to SQL injection attacks due to improper input sanitization. This flaw allows remote attackers to manipulate SQL queries, potentially leading to unauthorized data access, modification, or deletion. The exploit has been publicly disclosed, increasing the risk of exploitation in the wild.

Critical Impact

Remote attackers can exploit this SQL injection vulnerability to extract sensitive database information, bypass authentication mechanisms, or potentially compromise the entire backend database of the food ordering system.

Affected Products

• Campcodes Online Food Ordering System 1.0
• Web applications using the vulnerable /view-ticket-admin.php endpoint

Technical Details for CVE-2025-4490

Vulnerability Analysis

This SQL injection vulnerability occurs in the administrative ticket viewing functionality of the Campcodes Online Food Ordering System. The application fails to properly validate or sanitize the ID parameter before incorporating it into SQL queries. This allows attackers to inject malicious SQL statements that are then executed by the database server with the privileges of the application's database user.

The vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), which encompasses injection flaws where user-controlled input is improperly handled before being used in commands or queries. The network-accessible attack vector means no local access is required, and the attack can be executed without authentication or user interaction.

Root Cause

The root cause of this vulnerability is the lack of proper input validation and parameterized queries in the /view-ticket-admin.php file. The ID parameter is directly concatenated into SQL queries without sanitization, prepared statements, or input filtering. This allows special SQL characters and commands to be interpreted as part of the query structure rather than as data values.

Attack Vector

The attack can be initiated remotely over the network against any exposed instance of the Campcodes Online Food Ordering System. An attacker would craft malicious HTTP requests targeting the /view-ticket-admin.php endpoint with specially crafted ID parameter values containing SQL injection payloads.

The vulnerability allows for various SQL injection techniques including:

• Union-based injection - Extracting data from other database tables by appending UNION SELECT statements
• Error-based injection - Using database error messages to enumerate database structure and extract information
• Boolean-based blind injection - Inferring data through application behavior differences based on true/false SQL conditions
• Time-based blind injection - Using database sleep functions to extract data bit by bit

Detection Methods for CVE-2025-4490

Indicators of Compromise

• Unusual or malformed requests to /view-ticket-admin.php containing SQL syntax characters such as single quotes, double dashes, semicolons, or UNION keywords
• Database error messages appearing in application logs or responses indicating SQL syntax errors
• Unexpected database queries in slow query logs or database monitoring tools
• Evidence of data exfiltration or unauthorized access to ticket records or other database tables

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect and block SQL injection patterns in the ID parameter
• Enable detailed logging on the web server and database to capture suspicious query patterns
• Deploy network intrusion detection systems (IDS) with SQL injection signature rules
• Use SentinelOne Singularity to monitor for anomalous process behavior and data access patterns on servers hosting this application

Monitoring Recommendations

• Monitor HTTP access logs for requests to /view-ticket-admin.php with suspicious parameter values
• Set up alerts for database query failures or unusual query patterns originating from the web application
• Implement application-level logging to track all database interactions and flag potential injection attempts
• Conduct regular security scans of the web application to identify injection vulnerabilities

How to Mitigate CVE-2025-4490

Immediate Actions Required

• Take the affected application offline or restrict access to the /view-ticket-admin.php endpoint until a patch is applied
• Implement input validation to allow only numeric values for the ID parameter
• Deploy a Web Application Firewall with SQL injection protection enabled
• Review application logs and database audit trails for evidence of prior exploitation
• Consider network segmentation to limit database access from compromised web servers

Patch Information

At the time of publication, no official vendor patch has been released for this vulnerability. Organizations using Campcodes Online Food Ordering System 1.0 should contact the vendor for remediation guidance or consider implementing the workarounds below. Additional details may be available at the VulDB entry or the CampCodes website.

Workarounds

• Implement prepared statements with parameterized queries in the vulnerable PHP code to properly handle the ID parameter
• Add strict input validation to ensure the ID parameter contains only numeric values
• Deploy a WAF rule to filter and block requests containing SQL injection patterns
• Restrict access to administrative endpoints like /view-ticket-admin.php via IP whitelisting or VPN
• Consider disabling or removing the vulnerable functionality until a proper fix is implemented

# Example: Apache mod_rewrite rule to block suspicious ID parameter values
# Add to .htaccess or Apache configuration
RewriteEngine On
RewriteCond %{QUERY_STRING} .*['].*|.*union.*select.*|.*--.*|.*;.* [NC]
RewriteCond %{REQUEST_URI} /view-ticket-admin\.php [NC]
RewriteRule .* - [F,L]
