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]

|
||
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.

|
||
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
|
||
