Discovery Status:
=================
Published
Affected Product(s):
====================
Apple AppStore
Product: File Hub - Mobile Web Application 1.9.1
Exploitation Technique:
=======================
Remote
Severity Level:
===============
Critical
Technical Details & Description:
================================
1.1
A critical remote code execution web vulnerability has been discovered in the
official File Hub v1.9.1 iOS mobile web-application.
The web vulnerability allows remote attackers to execute unauthorized system
specific codes or commands to compromise the affected system/service.
The vulnerability is located in the `folder rename via edit` and `new folder`
function of the file hub wifi application interface. Remote attackers
are able to inject own system specific codes as folder/path name to compromise
the application. The code execution occurs after the inject via POST
method in the main index and the sub category folder. In the sub category
folder the code executes in the header location of the application context.
In the main index the code execution occurs in the index file dir & item list.
The security risk of the remote code execution vulnerability in the
new folder function is estimated as critical with a cvss (common vulnerability
scoring system) count of 9.3(+)|(-)9.4.
Exploitation of the code execution vulnerability requires no user interaction
or privileged mobile web-application user account with password.
Successful exploitation of the remote code execution vulnerability results in
mobile application or connected device component compromise.
Request Method(s):
[+] [POST]
Vulnerable Module(s):
[+] New Folder (Add)
Vulnerable Parameter(s):
[+] folder name
Affected Module(s):
[+] Index File Dir Item List - Path Dir
Location on Top
[+] Sub Category - Header Location to Path
1.2
A local file include web vulnerability has been discovered in the official File
Hub v1.9.1 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 web-application or mobile device.
The web vulnerability is located in the `file name` value of the `Files to
Upload` module POST method request. Remote attackers are
able to inject own files with malicious filename to compromise the mobile
application. The attack vector is persistent and the request
method is POST. The local file/path include execution occcurs in the main file
to path section after the refresh of the file upload.
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(+)|(-)7.4.
Exploitation of the local file include web vulnerability requires no user
interaction or privileged web-application user account with password.
Successful exploitation of the local web vulnerability results in mobile
application or connected device component compromise by unauthorized
local file include web attacks.
Request Method(s):
[+] [POST]
Vulnerable Input(s):
[+] Files to Upload
Vulnerable Parameter(s):
[+] filename
Affected Module(s):
[+] Index File Dir Item List
[+] Sub Category File Dir Item List
[+] Index File or Item Edit
[+] Index File or Item Remove/Delete
Proof of Concept (PoC):

Solution - Fix & Patch:
=======================
1.1
The remote code execution vulnerability can be patched by a secure restriction
and parse of the vulnerable rename and folder name values.
1.2
The local file include web vulnerability can be patched by a secure parse and
encode of file names. Ensure also that the values in the index and
sub category item list are prepared with a secure validation to prevent file
include or arbitrary file upload attacks.
Security Risk:
==============
1.1
The security risk of the remote code execution web vulnerability is estimated
as critical.
1.2
The security risk of the local file include web vulnerability is estimated as
high.
