Vulnerabilidades do SureCart SureCart – Ecommerce Made Easy For Selling Physical Products, Digital Downloads, Subscriptions, Donations, & Payments

The SureCart – Ecommerce Made Easy For Selling Physical Products, Digital Downloads, Subscriptions, Donations, & Payments plugin for WordPress is vulnerable to Stored Cross-Site Scripting via the 'comment' parameter in all versions up to, and including, 4.9.4 due to insufficient input sanitization and output escaping. This makes it possible for unauthenticated attackers to inject arbitrary web scripts in pages that will execute whenever a user accesses an injected page. Successful execution requires the affected comment to appear on a post that loads the surecart-components runtime (e.g. via a [sc_buy_button] shortcode) and contains no sc-checkout element, as these conditions trigger the innerHTML sink in sc-cart-loader.

The SureCart plugin for WordPress is vulnerable to privilege escalation via account takeover in versions up to, and including, 4.2.3. This is due to the plugin not properly validating a user's identity prior to updating their details like email during customer profile synchronization from webhook events. This makes it possible for unauthenticated attackers to change linked user's email addresses, including administrators if the administrator account is linked to a SureCart customer record, and leverage that to reset the user's password and gain access to their account if the customer ID is known.
