Drag and Drop Multiple File Upload – Contact Form 7 <= 1.3.8.5 - Limited Arbitrary File Deletion

The Drag and Drop Multiple File Upload – Contact Form 7 plugin for WordPress is vulnerable to limited arbitrary file deletion due to insufficient file path validation in the dnd_codedropz_upload_delete() function in all versions up to, and including, 1.3.8.5. This makes it possible for unauthenticated attackers to delete limited arbitrary files on the server. It is not possible to delete files like wp-config.php that would make RCE possible.

The attempt arrives as an ordinary request to Drag and Drop Multiple File Upload for Contact Form 7: WordSec's web application firewall inspects request payloads before WordPress loads them. Classes like this one can leave something behind, so the staged malware scanner is the second half: it looks for dropped files and modified code rather than for the request that created them. None of that substitutes for the fix: Drag and Drop Multiple File Upload for Contact Form 7 1.3.8.6 closes this, and updating the plugin is the step that ends it.
