Technical Details & Description:
==============================
A local file include web vulnerability has been discovered in the official Photorange v1.0 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 mobile web-application.
The web vulnerability is located in the `filename` value of the `add file` module. Remote attackers are able to inject own files with
malicious `filename` values in the `sync` device POST method request to compromise the mobile web-application. The local file/path include
execution occcurs in the file dir index web interface through the download path next to the vulnerable name/path value. The attacker is able
to inject the local file request by usage of the available `wifi interface` for file exchange via sync.
Remote attackers are also able to exploit the filename validation issue in combination with persistent injected script codes to execute
different local malicious attack requests. The attack vector is on the application-side of the wifi service and the request method to
inject is POST via Sync.
The security risk of the local file include web vulnerability is estimated as high with a cvss (common vulnerability scoring system)
count of 6.3. Exploitation of the local file include web vulnerability requires no privileged web-application user account but low
user interaction. Successful exploitation of the local file include web vulnerability results in mobile application or connected
device component compromise.
Request Method(s):
[+] [Sync] [POST]
Vulnerable Parameter(s):
[+] filename
Affected Module(s):
[+] Index File Dir Listing (Web Interface - http://localhost:9900/ )
Proof of Concept (PoC):
=======================
The local file include web vulnerability can be exploited by local attackers without privileged application user account or user interaction.
For security demonstration or to reproduce the security vulnerability follow the provided information and steps below to continue.
