What is CVE-2018-18966?

osCommerce version 2.3.4.1 contains a vulnerability stemming from an incomplete implementation of blacklist filtering within the .htaccess file for the product page. Although the .htaccess restricts access to files with the .html extension, Internet Explorer is capable of rendering HTML content from files with a .eml extension. This oversight may potentially expose sensitive data or allow unauthorized script execution, highlighting a critical need for enhanced security measures in web application configurations.
