Technical Details & Description:
================================
1.1
A local file include web vulnerability has been discovered in the official OnDemandWorld \
Wireless Drive v1.1.0 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 or mobile device.
The web vulnerability is located in the `filename` value of the `Upload file` module. Remote \
attackers are able to inject own files with malicious `filename` value in the upload POST \
method request to compromise the mobile web-application. The attack vector is persistent and \
the request method is POST. The local file/path include execution occcurs in the main file dir \
list. The security risk of the local file include web vulnerability is estimated as high(+) \
with a cvss (common vulnerability scoring system) count of 6.7(+)|(-)6.8.
Exploitation of the local file include web vulnerability requires no user interaction but a \
privileged web-application user account with low user auth. Successful exploitation of the \
local file include web vulnerability results in mobile application or connected device \
component compromise.
Request Method(s):
[+] [POST]
Vulnerable Module(s):
[+] Upload file
Vulnerable Parameter(s):
[+] filename
Affected Module(s):
[+] Upload > Menu File Dir List (http://localhost:4096)
1.2
A local command/path injection web vulnerabilities has been discovered in the official \
OnDemandWorld Wireless Drive v1.1.0 iOS mobile web-application. A command inject vulnerability \
allows attackers to inject local commands via vulnerable system values to compromise the apple \
mobile iOS application.
The vulnerability is located in the vulnerable `[foldername]` value of the wifi file dir list \
module. Local attackers are able to inject own malicious system specific commands or path \
value requests in the vulnerable foldername value. The injection requires an active sync with \
the wifi app stored folders. The execution of the local command inject via foldername value on \
sync occurs in the file dir index list of the main upload path. The security risk of the local \
command/path inject vulnerability is estimated as high(-) with a cvss (common vulnerability \
scoring system) count of 5.6(+)|(-)5.7.
Exploitation of the command/path inject vulnerability requires a low privileged iOS device \
account with restricted access and no user interaction. Successful exploitation of the \
vulnerability results in unauthorized execution of system specific commands and unauthorized \
path value requests to compromise the mobile iOS application or the connected device \
components.
Request Method(s):
[+] Sync
Vulnerable Parameter(s):
[+] foldername (path value)
Affected Module(s):
[+] Index- File Dir Listing
[+] Sub Folder/Category - File Dir Listing
Proof of Concept (PoC):
=======================
1.1
The local file include web vulnerability can be exploited by remote attackers without user \
interaction and with low privileged web-interface account. For security demonstration or to \
reproduce the security vulnerability follow the provided information and steps below to \
continue.

The command inject vulnerability can be exploited by local attackers with physical device \
access or low privileged user account and without user interaction. For security demonstration \
or to reproduce the security vulnerability follow the provided information and steps below to \
continue.

Solution - Fix & Patch:
=======================
1.1
The local file include web vulnerability can be patched by a secure parse and encode of the \
vulnerable filename value in the upload file POST method request. Encode also the filename \
index listing to prevent execution of malicious commands, injection of script codes or file \
include attacks.
1.2
The local command inject web vulnerability can be patched by a secure parse and restriction of \
the rename and foldername value in the wifi app. Encode also the output index list were the \
folders will become visible after the sync.
Security Risk:
==============
1.1
The security risk of the local file include web vulnerability in the wifi exchange interface is \
estimated as high(+).
1.2
The local command inject vulnerability in the foldername value via sync is estimated as \
high(-).
