CVE-2025-7607: Simple Shopping Cart SQL Injection Flaw

CVE-2025-7607 Overview

CVE-2025-7607 is a SQL injection vulnerability discovered in code-projects Simple Shopping Cart version 1.0. The vulnerability exists in the /Customers/save_order.php file, where improper handling of the order_price argument allows attackers to inject malicious SQL queries. This flaw enables remote attackers to manipulate database queries without authentication, potentially compromising sensitive customer and order data.

Critical Impact

Unauthenticated remote attackers can exploit this SQL injection vulnerability to extract, modify, or delete database contents, potentially compromising customer data and order information in e-commerce deployments.

Technical Details for CVE-2025-7607

Vulnerability Analysis

This SQL injection vulnerability (CWE-89) arises from improper neutralization of special elements used in SQL commands within the order processing functionality. The affected endpoint /Customers/save_order.php fails to properly sanitize or parameterize the order_price argument before incorporating it into database queries. This constitutes a classic injection flaw (CWE-74) where user-controlled input is directly concatenated into SQL statements.

The vulnerability is exploitable over the network without requiring authentication or user interaction, making it accessible to any remote attacker who can reach the application endpoint. Successful exploitation could result in unauthorized data access, data manipulation, or potential data loss affecting confidentiality, integrity, and availability of the shopping cart system.

Root Cause

The root cause is insufficient input validation and the lack of parameterized queries in the save_order.php file. The order_price parameter is directly incorporated into SQL queries without proper sanitization, escaping, or the use of prepared statements. This allows attackers to break out of the intended query context and inject arbitrary SQL commands.

Attack Vector

The attack vector is network-based, requiring no authentication or privileges. An attacker can craft malicious HTTP requests to the /Customers/save_order.php endpoint with a specially crafted order_price parameter containing SQL injection payloads. The injected SQL code is then executed by the database server with the privileges of the application's database user.

The vulnerability can be exploited through standard HTTP POST requests to the affected endpoint. By manipulating the order_price field, attackers can inject SQL syntax that alters the intended query behavior. Common exploitation techniques include UNION-based injection to extract data from other tables, blind SQL injection to infer database contents, or time-based techniques for data exfiltration. For detailed technical information, refer to the GitHub CVE Issue Tracker and VulDB Entry #316307.

Detection Methods for CVE-2025-7607

Indicators of Compromise

• Unusual or malformed requests to /Customers/save_order.php containing SQL syntax characters such as single quotes, double dashes, UNION statements, or semicolons
• Database error messages in application logs indicating syntax errors or unexpected query results
• Anomalous database queries in database server logs, particularly those targeting the orders table or attempting to access other tables
• Evidence of data exfiltration or unauthorized data modifications in order records

Detection Strategies

• Deploy Web Application Firewall (WAF) rules to detect and block SQL injection patterns in requests to /Customers/save_order.php
• Implement application-level logging to capture all requests containing the order_price parameter for security analysis
• Configure database query logging and establish baselines to identify anomalous query patterns
• Use intrusion detection systems (IDS) with signatures for common SQL injection attack patterns

Monitoring Recommendations

• Monitor web server access logs for requests to /Customers/save_order.php containing unusual characters or encoded payloads
• Set up alerts for database errors that may indicate injection attempts or successful exploitation
• Review database audit logs for unauthorized SELECT, INSERT, UPDATE, or DELETE operations
• Implement real-time monitoring for changes to critical order and customer tables

How to Mitigate CVE-2025-7607

Immediate Actions Required

• Immediately restrict access to the /Customers/save_order.php endpoint if the application is internet-facing
• Implement input validation on the order_price parameter to accept only numeric values
• Deploy a Web Application Firewall with SQL injection protection rules as a temporary mitigation
• Review application logs for evidence of prior exploitation attempts
• Consider taking the affected application offline until a proper fix can be implemented

Patch Information

No official vendor patch is currently available for this vulnerability. Organizations using Simple Shopping Cart 1.0 should implement the recommended workarounds and consider migrating to a more actively maintained e-commerce solution. Monitor the Code Projects Resource page for any updates or security announcements.

Workarounds

• Implement parameterized queries (prepared statements) in the save_order.php file to prevent SQL injection
• Add strict input validation to ensure order_price only accepts numeric values with appropriate format validation
• Deploy WAF rules specifically blocking SQL injection patterns targeting the affected endpoint
• Restrict network access to the application to trusted IP ranges only
• Implement database user privilege restrictions to limit the impact of successful SQL injection

# Example Apache .htaccess configuration to restrict access
<Files "save_order.php">
    # Restrict access to trusted networks only
    Require ip 192.168.1.0/24
    Require ip 10.0.0.0/8
</Files>
