Carga sin restricciones de archivos con vulnerabilidad de tipo peligroso en WPChill Download Monitor. Este problema afecta a Download Monitor: desde n/a hasta 4.8.3.

The Download Monitor plugin for WordPress is vulnerable to arbitrary file uploads due to missing file type validation and access controls on the 'upload_file' function in versions up to, and including, 4.8.3. This makes it possible for authenticated attackers with subscriber-level capabilities or above to upload arbitrary files on the affected site's server which may make remote code execution possible.
