Severity Level:
===============
High
Technical Details & Description:
==============================
A local file include web vulnerability has been discovered in the official PhotoSync Wifi&Bluetooth 1.0 iOS mobile 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 `file list` context next to the vulnerable `filename` item value. The attacker is able to inject the
local malicious file request by usage of the available `wifi interface` (http://localhost:8000/) upload form.
Remote attackers are also able to exploit the filename 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 6.8. Exploitation of the local file include web vulnerability requires no privileged web-application user account or user interaction.
Successful exploitation of the local file include web vulnerability results in mobile application or connected device component compromise.

Vulnerable Service(s):
[+] PhotoSync Wifi&Bluetooth 1.0

Solution - Fix & Patch:
=======================
The file include web vulnerability can be patched by a secure encode of the vulnerable file name value. Encode and filter also the vulnerable output in
the images dir index listing file. Restrict the filename value input and filter the requests to prevent against further local file include attacks
against the main directory listing service.
Security Risk:
==============
The security risk of the local file include web vulnerability in the upload module of the mobile application is estimated as high.
