Directorist <= 7.2.2 - Authenticated (Admin+) Arbitrary File Upload

The Directorist plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation via the atbdp_download_file() AJAX action in versions up to, and including, 7.2.2. This makes it possible for authenticated attackers with administrative privileges to upload arbitrary files on the affected sites server which may make remote code execution possible. This only affects sites where administrator have been restricted in their uploading files capabilities.

An attacker needs Admin access first, so the firewall sees the attempt as traffic from a logged-in account: 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: Directorist 7.2.3 closes this, and updating the plugin is the step that ends it.
