Isotope eCommerce Order ID Guessing Vulnerability

Executive Summary

Isotope eCommerce through version 2.9.10 generates order identifiers using the uniqid() function, which is not cryptographically secure. This allows unauthenticated attackers to guess valid order IDs and access sensitive order details such as billing addresses, customer information, and purchased files by manipulating the uid parameter. Additionally, guest orders lack proper ownership verification, further enabling unauthorized access.

Detection Guidance

Check Isotope eCommerce versions for 2.9.10 or earlier. Inspect order ID generation in Order.php and OrderDetails.php for use of uniqid(). Monitor for unauthorized access attempts via uid parameter manipulation. Review logs for suspicious order detail requests.

This vulnerability likely violates GDPR due to unauthorized access to personal data (customer information, billing addresses) and HIPAA if protected health information is exposed. It results in non-compliance with data protection requirements, potentially leading to legal penalties, reputational damage, and loss of customer trust.

Mitigation Strategies

Upgrade Isotope eCommerce to version 2.9.11 or later. Replace uniqid() with cryptographically secure random token generation. Implement ownership verification for guest orders. Add input validation and prepared statements to prevent SQL injection. Restrict file uploads and disable XML entity expansion.
