Official description

The ShopLentor – WooCommerce Builder for Elementor & Gutenberg +21 Modules – All in One Solution plugin for WordPress is vulnerable to Email Relay Abuse in all versions up to, and including, 3.3.2. This is due to the lack of validation on the 'send_to', 'product_title', 'wlmessage', and 'wlemail' parameters in the 'woolentor_suggest_price_action' AJAX endpoint. This makes it possible for unauthenticated attackers to send arbitrary emails to any recipient with full control over the subject line, message content, and sender address (via CRLF injection in the 'wlemail' parameter), effectively turning the website into a full email relay for spam or phishing campaigns.

The underlying weakness: Improper Neutralization of CRLF Sequences

The product uses CRLF (carriage return line feeds) as a special element, e.g. to separate lines or records, but it does not neutralize or incorrectly neutralizes CRLF sequences from inputs.

How developers prevent this class of flaw

  • Appropriately filter or quote CRLF sequences in user-controlled input.
