/* explaination:

  if you have admin session id, you can enable avatar uploads, if not activated
  yet and you can store an arbitrary path for &#34;default_lang&#34; inside phpbb_config
  database table using the &#34;Database Restore&#34; feature. So you can upload a
  malicious avatar with php code as EXIF metadata content and submit a query like
  this:

  UPDATE phpbb_config SET config_value=CONCAT(&#34;english/../../images/avatars/297984465bc277af10.jpg&#34;,CHAR(0)) where config_name=&#34;default_lang&#34;;

  note: you can see avatar filename in profile page

  in faq.php, like in other files, near line 62, we have:

  ...
  include($phpbb_root_path . &#39;language/lang_&#39; . $board_config[&#39;default_lang&#39;] . &#39;/&#39; . $lang_file . &#39;.&#39; . $phpEx);
  ...

  $board_config[&#39;default_lang&#39;] var is not sanitized before to be used
  to include files, so you can reach the malicious avatar to execute the code
  inside of it.

  This tool also creates a &#34;suntzu&#34; user with password &#34;suntzu&#34; and a backdoor
  called suntzu.php, so you do not need sid after the first run
