Summary
A file upload vulnerability in CS Cart 4.18.3 allows unrestricted upload of HTML files, which are rendered directly in the browser. Attackers can upload crafted HTML files containing malicious content, such as fake login forms for credential harvesting or scripts for Cross-Site Scripting (XSS) attacks. Since the content is served from a trusted domain, it significantly increases the likelihood of successful phishing or script execution against other users.
