Technical Details & Description:
|
||
================================
|
||
A local file include web vulnerability has been discovered in the official WonderApplications Photo Org v8.3 iOS 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 `uploadMedia` (uploadfile) module. Remote attackers are able to inject
|
||
own files with malicious `filename` values in the `uploadMedia` POST method request to compromise the mobile web-application. The local
|
||
file/path include execution occcurs in the index file/folder list context 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/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 7.1. 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):
|
||
[+] [POST]
|
||
|
||
Vulnerable Service(s):
|
||

|
||
[+] uploadMedia
|
||
|
||
Vulnerable Parameter(s):
|
||
[+] filename
|
||
|
||
Affected Module(s):

|
||
|
||
|
||
Proof of Concept (PoC):
|
||
=======================
|
||
The local file inlcude web vulnerability can be exploited by remote attackers with low privileged application user account and without user interaction.

||
Solution - Fix & Patch:
|
||
=======================
|
||
The local file include web vulnerability bug can be patched by a secure parse and encode of the vulnerable filename value in the upload POST method request.
|
||
Encode also the filename value in the file dir listing of the index and sub categories.
|
||
Restrict the filename value name input and prevent executions by a secure file filter on upload extension or the name validation itself.
|
||
|
||
|
||
Security Risk:
|
||
==============
|
||
The security risk of the local file include web vulnerability in the filename value is estimated as high.
