Abstract:
=========
The Vulnerability Laboratory Research Team discovered multiple vulnerabilities in the mobile Wireless Disk PRO v2.3 app for the apple ipad & iphone.


Report-Timeline:

2013-02-26:  Public Disclosure


Status:
========
Published


Affected Products:
==================
Apple
Product: Wireless Disk PRO 2.3


Exploitation-Technique:
=======================
Remote


Severity:
=========
Critical


Details:
========
1.1
A local file include web vulnerability via POST request method is detected in the mobile Wireless Disk PRO v2.3 app for the apple ipad & iphone.
The vulnerability allows remote attackers via POST method to inject local app webserver folders to request unauthorized local webserver files.

The vulnerbility is located in the upload file module of the webserver (http://localhost:6566/) when processing to request a manipulated 
filename via POST. The execution of the injected path or file request will occur when the attacker is processing to reload to index listing 
of the affected module after the file include attack via upload.

Exploitation of the vulnerability requires no user interaction and also without application user account (no password standard).
Successful exploitation of the vulnerability results in unauthorized path or file access via local file or path include attack.

Vulnerable Application(s):
        [+] Wireless Disk PRO v2.3 - ITunes or AppStore (Apple)

Vulnerable Module(s):
        [+] File Upload  (Web Server) [Remote]

Vulnerable Parameter(s):
        [+] filename

Affected Module(s):
        [+] File - Index Listing



1.2
A local command injection web vulnerability is detected in the mobile Wireless Disk PRO v2.3 app for the apple ipad & iphone.
The vulnerability allows to inject local commands via vulnerable system values to compromise the apple mobile application.

The vulnerbility is located in the index module when processing to load the ipad or iphone device name. Local attackers can 
change the ipad or iphone device name to system specific commands and file/path requests to provoke the execution when 
processing to watch the index site of the application.

Exploitation of the web vulnerability requires a local privilege device user account (standard) without user interaction.
Successful exploitation of the vulnerability results unauthorized execution of system specific commands or file/path requests.

Vulnerable Application(s):
        [+] Wireless Disk PRO v2.3 - ITunes or AppStore (Apple)

Vulnerable Module(s):
        [+] Index

Vulnerable Parameter(s):
        [+] device name

Affected Module(s):
        [+] Header Device - Index File Dir Listing



1.3
A persistent input validation vulnerability is detected in the mobile Wireless Disk PRO v2.3 app for the apple ipad & iphone.
The bug allows an attacker (remote) to implement/inject malicious script code on the application side (persistent) of the app web service. 

The vulnerability is located in the index file dir listing module of the webserver (http://localhost:6566/) when processing to display
injected and via POST request method manipulated filenames. The persistent script code will be executed out of the main index file dir 
listing module when the service is processing to list the new malicious injected filename as item.

Exploitation of the persistent web vulnerability requires low or medium user interaction without application user account.
Successful exploitation of the vulnerability can lead to persistent session hijacking (customers), account steal via persistent web 
attacks, persistent phishing or stable (persistent) certificate mail notification context manipulation.

Vulnerable Application(s):
        [+] Wireless Disk PRO v2.3 - ITunes or AppStore (Apple)

Vulnerable Module(s):
        [+] File Upload  (Web Server) [Remote]

Vulnerable Parameter(s):
        [+] name

Affected Module(s):
        [+] Filename - Index File Dir Listing


Proof of Concept:
=================
1.1
The file include web vulnerability can be exploited by remote attackers without application user account and also without user interaction. 
For demonstration or reproduce ...

PoC: (POST)
-----------------------------243701706111075
Content-Disposition: form-data; name="file"; filename="[FILE/PATH INCLUDE WEB VULNERABILITY].png"
Content-Type: image/gif  flag: 137


1.2
The command injection web vulnerability can be exploited by local privilege device user accounts with low required user interaction.
For demonstration or reproduce ...

DEVICE NAME: IPad360 ¥337

Standard Application Header:
<div id="header_bottom">The following files are the hosts live from IPad360 ¥337 WirelessDisk App Document folder</div>

Manipulated Application Header:
<div id="header_bottom">The following files are the hosts live from [COMMAND INJECTION VIA DEVICENAME!] WirelessDisk App Document folder</div>


1.3
The persistent script code injection web vulnerability can be exploited by remote attackers without application user account 
and with medium required user interaction. For demonstration or reproduce ...

Risk:
=====
1.1
The security risk of the local file/path include web vulnerability via POST request method is estimated as critical.

1.2
The security risk of the local command injection vulnerability is estimated as high(-).

1.3
The security risk of the persistent input validation web vulnerability is estimated as medium(+).
