Technical Details & Description:
==============================
1.1
A local file include web vulnerability has been discovered in the official TigerCom iFolder+ v1.2 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 `uploadfile` module. Remote attackers are able to inject own files
with malicious `filename` values in the `uploadfile` POST method request to compromise the mobile web-application. The local file/path
include execution occcurs in the index `folder list` context next to the vulnerable filename value. The attacker is able to inject the
local file request by usage of the available `wifi interface` for file or folder exchange/share.
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 7.3. 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):
[+] iFolder+ v1.2
Vulnerable Module(s):
[+] uploadfile
Vulnerable Parameter(s):
[+] filename
Affected Module(s):
[+] Index Folder Dir Listing (http://localhost:8080/)
1.2
An arbitrary file upload web vulnerability has been discovered in the official TigerCom iFolder+ v1.2 iOS mobile web-application.
The arbitrary file upload issue allows remote attackers to upload files with multiple extensions to bypass the web-server or system validation.
The vulnerability is located in the `uploadfile` module. Remote attackers are able to upload a php or js web-shells by renaming the file with
multiple extensions to bypass the file restriction mechanism. The attacker uploads for example a web-shell with the following name and extension
`image.jpg.gif.js.php.jpg`. After the upload the attacker needs to open the file in the web application. He deletes the .jpg & . gif file
extension and can access the application file with elevated access rights.
The security risk of the arbitrary file upload web vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 7.4.
Exploitation of the arbitrary file upload web vulnerability requires no user interaction or privilege application user account with password.
Successful exploitation of the vulnerability results in unauthorized file access because of a compromise after the upload of web-shells.

[+] [POST]
Vulnerable Module(s):

Solution - Fix & Patch:
=======================
1.1
The file inlcude vulnerability can be patched by a secure parse and encode of the filename value in the upload file POSt method request.
1.2
The arbitrary file upload issue can be fixed by a secure restriction and filter procedure in the filename type validation mechanism.
Restrict the input and check for extentions to prevent arbitrary file upload with further exploitation.
Security Risk:
==============
1.1
The security risk of the local file include web vulnerability is estimated as high.
1.2
The security risk of the arbitrary file upload web vulnerability is estimated as critical.
