Technical details
The uploader.php component processes file uploads via the getContent task with no authentication or ACL enforcement in the dispatch chain. Although the code validates MIME type via magic bytes, the extension allowlist was commented out, permitting attackers to submit image/PHP polyglots (files with valid image headers followed by PHP code) while specifying arbitrary .php extensions. The uploaded file is written directly to the web root and executed as PHP, allowing unauthenticated remote code execution.
