CVE-2016-15042

Frontend File Manager < 4.0 & N-Media Post Front-end Form < 1.1 & - Arbitrary File Upload

9.8 CriticalPublic exploit

The Frontend File Manager (versions < 4.0), N-Media Post Front-end Form (versions < 1.1) plugins for WordPress are vulnerable to arbitrary file uploads due to missing file type validation via the nm_filemanager_upload_file and nm_postfront_upload_file AJAX actions. This makes it possible for unauthenticated attackers to upload arbitrary files on the affected sites server which may make remote code execution possible.
