CVE-2025-4930: Campcodes Shopping Portal SQLi Vulnerability

CVE-2025-4930 Overview

A critical SQL injection vulnerability has been discovered in Campcodes Online Shopping Portal version 1.0. The vulnerability exists in the /my-cart.php file, where the billingaddress parameter is not properly sanitized, allowing attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries, potentially leading to unauthorized data access, data modification, or complete database compromise.

Critical Impact
Remote attackers can exploit this SQL injection vulnerability to extract sensitive customer data, modify database records, or potentially gain unauthorized access to the underlying server through the e-commerce platform.

Affected Products

Campcodes Online Shopping Portal 1.0
E-commerce platforms utilizing the affected /my-cart.php component
Web applications with unpatched Campcodes Online Shopping Portal installations

Technical Details for CVE-2025-4930

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) stems from improper neutralization of special elements used in SQL commands within the /my-cart.php file. The billingaddress parameter accepts user-supplied input that is directly incorporated into SQL queries without adequate sanitization or parameterization. This allows attackers to break out of the intended query structure and execute arbitrary SQL commands against the backend database.

The vulnerability is classified under both CWE-89 (SQL Injection) and CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), indicating that user input is being passed to the database layer without proper encoding or validation.

Root Cause

The root cause of this vulnerability is the lack of input validation and parameterized queries in the /my-cart.php file. When processing billing address information during the cart checkout process, the application directly concatenates user-supplied data into SQL query strings rather than using prepared statements or properly escaping special characters. This classic SQL injection pattern allows attackers to inject SQL metacharacters that alter the logic of database queries.

Attack Vector

The attack can be launched remotely over the network without requiring authentication. An attacker can craft malicious HTTP requests to the /my-cart.php endpoint with a specially crafted billingaddress parameter containing SQL injection payloads. Since the exploit has been publicly disclosed, attackers have readily available information on how to exploit this vulnerability.

The attack does not require any user interaction and can be automated, making it particularly dangerous for exposed e-commerce installations. Successful exploitation could allow attackers to:

Extract sensitive customer information including personal data and payment details
Modify or delete database records
Bypass authentication mechanisms
Potentially escalate to command execution depending on database configuration

Technical details about the exploitation method can be found in the GitHub Issue documenting this CVE.

Detection Methods for CVE-2025-4930

Indicators of Compromise

Unusual SQL error messages appearing in application logs related to the /my-cart.php endpoint
Web server access logs showing requests to /my-cart.php with suspicious characters in the billingaddress parameter (e.g., single quotes, UNION SELECT, OR 1=1)
Database query logs indicating malformed or unexpected queries originating from the cart functionality
Unexpected database access patterns or data exfiltration attempts

Detection Strategies

Implement Web Application Firewall (WAF) rules to detect and block SQL injection attempts targeting the billingaddress parameter
Monitor HTTP request logs for common SQL injection patterns such as ', --, UNION, SELECT, and OR 1=1 in request parameters
Deploy application-level logging to capture and alert on database query anomalies from the /my-cart.php component
Utilize intrusion detection systems (IDS) with SQL injection signature rules

Monitoring Recommendations

Enable detailed logging on the web server and database to capture all requests to /my-cart.php and associated queries
Set up real-time alerts for SQL syntax errors or injection pattern matches in application logs
Regularly review database audit logs for unauthorized data access or modification attempts
Monitor network traffic for data exfiltration patterns that may indicate successful exploitation

How to Mitigate CVE-2025-4930

Immediate Actions Required

Immediately restrict access to the /my-cart.php endpoint if the cart functionality is not critical to operations
Deploy a Web Application Firewall (WAF) with SQL injection protection rules as an interim measure
Audit database access logs to determine if exploitation has already occurred
Consider taking the affected e-commerce portal offline until a proper fix can be implemented

Patch Information

At the time of publication, no official patch has been released by Campcodes for this vulnerability. Organizations running Campcodes Online Shopping Portal 1.0 should monitor the Campcodes website for security updates and patch releases. Additional vulnerability tracking information is available through VulDB.

Workarounds

Implement prepared statements with parameterized queries for all database interactions in /my-cart.php if source code access is available
Add input validation to sanitize the billingaddress parameter, rejecting or escaping SQL metacharacters before processing
Deploy a WAF rule specifically targeting the billingaddress parameter to filter malicious input
Restrict database user privileges to minimum required permissions to limit the impact of successful SQL injection

If you have access to modify the application code, implement parameterized queries. The general approach involves replacing direct string concatenation in SQL queries with prepared statements that separate SQL logic from user data. Consult PHP documentation on PDO prepared statements or MySQLi prepared statements for implementation guidance.
