The Vulnerability Laboratory Core Research Team discovered file include web 
vulnerability in the official Wifi Drive Pro v1.2 iOS mobile application.


Vulnerability Disclosure Timeline:
==================================
2015-03-13: Public Disclosure (Vulnerability Laboratory)


Discovery Status:
=================
Published


Affected Product(s):
====================
Mindspeak Software
Product: Wifi Drive Pro - iOS Mobile Web Application 1.2


Exploitation Technique:
=======================
Local


Severity Level:
===============
High


Technical Details & Description:
================================
A local file include web vulnerability has been discovered in the official 
Mindspeak Software - Wifi Drive Pro v1.2 iOS mobile web-application.
The local file include web vulnerability allows remote attackers to 
unauthorized include local file/path requests or system specific path commands 
to compromise the mobile web-application.

The web vulnerability is located in the `filename` value of the `file upload` 
module. Remote attackers are able to inject own files with malicious 
`filename` values in the `file upload` POST method request to compromise the 
mobile web-application. The local file/path include execution occcurs in 
the index file dir listing of the wifi interface. The attacker is able to 
inject the local file include request by usage of the `wifi interface` 
in connection with the vulnerable file upload POST method request. 

Remote attackers are also able to exploit the filename issue in combination 
with persistent injected script codes to execute different malicious 
attack requests. The attack vector is located on the application-side of the 
wifi service and the request method to inject is POST. 

The security risk of the local file include web vulnerability is estimated as 
high with a cvss (common vulnerability scoring system) count of 6.4. 
Exploitation of the local file include web vulnerability requires no user 
interaction or privileged web-application user account. Successful exploitation 
of the local file include web vulnerability results in mobile application 
compromise or connected device component compromise.

Request Method(s):
                                [+] [POST]

Vulnerable Module(s):
                                [+] File Upload

Vulnerable Parameter(s):
                                [+] filename

Solution - Fix & Patch:
=======================
The vulnerability can be patched by a secure validation of the filename value 
in the upload POST method request. Restrict the filename input and 
disallow special chars. Ensure that not multiple file extensions are loaded in 
the filename value to prevent arbitrary file upload attacks.
Encode the output in the file dir index list with the vulnerable name value to 
prevent an application-side injection attacks.


Security Risk:
==============
The security risk of the local file include web vulnerability in the upload 
POST method request is estimated as high. (CVSS 6.3)
