CVE-2025-11070: Online Shopping System SQLi Vulnerability

CVE-2025-11070 Overview

A SQL Injection vulnerability has been identified in Projectworlds Online Shopping System version 1.0. This vulnerability affects the /store/cart_add.php file, where improper handling of the ID parameter allows attackers to inject malicious SQL queries. The vulnerability can be exploited remotely without authentication, potentially allowing unauthorized access to the underlying database, data manipulation, and information disclosure.

Critical Impact

Remote attackers can exploit this SQL Injection vulnerability to extract sensitive data from the database, modify or delete records, and potentially gain further access to the underlying system through database exploitation techniques.

Technical Details for CVE-2025-11070

Vulnerability Analysis

This vulnerability is classified under CWE-74 (Improper Neutralization of Special Elements in Output Used by a Downstream Component), commonly referred to as Injection. The flaw exists in the shopping cart functionality of the application, specifically in how the cart_add.php script processes the ID parameter.

When a user adds an item to their shopping cart, the application passes an ID parameter to identify the product. The vulnerable code fails to properly sanitize or parameterize this input before incorporating it into SQL queries. This allows an attacker to craft malicious input that alters the intended SQL query structure, enabling them to execute arbitrary database commands.

The exploit has been publicly disclosed, increasing the risk of widespread exploitation against vulnerable installations. Additional technical details are available in the GitHub Issue CVE Discussion and VulDB entry #326109.

Root Cause

The root cause of this vulnerability is improper input validation and the lack of parameterized queries (prepared statements) in the cart_add.php file. User-supplied input from the ID parameter is directly concatenated into SQL query strings without proper sanitization or escaping. This allows special SQL characters and commands to be interpreted by the database engine rather than being treated as literal data values.

Attack Vector

The attack can be performed remotely over the network without requiring authentication. An attacker can manipulate the ID parameter in HTTP requests to the /store/cart_add.php endpoint. By injecting SQL syntax into this parameter, the attacker can modify the query logic to:

• Extract sensitive information from database tables (usernames, passwords, payment details)
• Bypass authentication mechanisms
• Modify or delete database records
• Potentially escalate to operating system command execution depending on database configuration

The vulnerability requires no user interaction and can be exploited directly through crafted HTTP requests to the vulnerable endpoint.

Detection Methods for CVE-2025-11070

Indicators of Compromise

• Unusual or malformed requests to /store/cart_add.php containing SQL syntax characters such as single quotes ('), double dashes (--), semicolons (;), or SQL keywords like UNION, SELECT, DROP
• Database error messages appearing in web server logs or responses
• Unexpected database queries or query patterns in database logs
• Signs of data exfiltration or unauthorized database access

Detection Strategies

• Implement Web Application Firewall (WAF) rules to detect SQL injection patterns in the ID parameter
• Monitor web server access logs for suspicious requests to /store/cart_add.php with encoded or obfuscated SQL payloads
• Deploy intrusion detection systems (IDS) with SQL injection detection signatures
• Enable database query logging and monitor for anomalous query patterns

Monitoring Recommendations

• Set up real-time alerting for SQL error messages in application logs
• Monitor network traffic for large data transfers from the database server that could indicate data exfiltration
• Implement database activity monitoring (DAM) to detect unauthorized queries
• Review web application logs regularly for patterns consistent with SQL injection probing or exploitation attempts

How to Mitigate CVE-2025-11070

Immediate Actions Required

• Remove or restrict public access to the Projectworlds Online Shopping System if it is exposed to the internet
• Implement input validation to reject any non-numeric characters in the ID parameter
• Deploy a Web Application Firewall (WAF) with SQL injection protection rules as a temporary protective measure
• Review database logs for evidence of previous exploitation attempts

Patch Information

At the time of this publication, no official vendor patch has been released for Projectworlds Online Shopping System 1.0. Organizations using this software should monitor the VulDB entry and GitHub discussion for updates regarding patches or official guidance from the vendor.

Workarounds

• Modify the cart_add.php file to use prepared statements (parameterized queries) instead of string concatenation for SQL queries
• Implement strict input validation to ensure the ID parameter only accepts integer values
• Consider disabling the affected functionality until a proper fix can be implemented
• Use database user accounts with minimal privileges for the web application to limit the impact of successful exploitation

# Recommended remediation: Use prepared statements
# Replace direct query concatenation with parameterized queries

# Example using PDO prepared statements:
$stmt = $pdo->prepare("SELECT * FROM products WHERE id = :id");
$stmt->bindParam(':id', $id, PDO::PARAM_INT);
$stmt->execute();
