Description

The AIT CSV import/export plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation in the /wp-content/plugins/ait-csv-import-export/admin/upload-handler.php file in versions up to, and including, 3.0.3. This makes it possible for unauthorized attackers to upload arbitrary files on the affected sites server which may make remote code execution possible.
