/* explaination:
if you have admin session id, you can enable avatar uploads, if not activated
yet and you can store an arbitrary path for "default_lang" inside phpbb_config
database table using the "Database Restore" 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("english/../../images/avatars/297984465bc277af10.jpg",CHAR(0)) where config_name="default_lang";
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 . 'language/lang_' . $board_config['default_lang'] . '/' . $lang_file . '.' . $phpEx);
...
$board_config['default_lang'] 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 "suntzu" user with password "suntzu" and a backdoor
called suntzu.php, so you do not need sid after the first run
