  name: WordPress SimpleFilelist - Remote Code Execution
  author: princechaddha
  severity: critical
  description: |
    Simple File List WordPress plugin was found to be vulnerable to an unauthenticated arbitrary file upload leading to remote code execution. The Python exploit first uploads a file containing PHP code but with a png image file extension. A second request is sent to move (rename) the png file to a PHP file.
