Critical  
  
  
Details:  
========  
1.1  
A local file include web vulnerability via POST request method is detected in the Air Disk Wireless HTTP File Sharing 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://192.168.0.10:8988/) when processing to load a manipulated   
filename via POST. The execution of the injected path or file request will occur when the attacker is opening the main index file dir listing.   
  
Exploitation of the web vulnerability does not require a privileged application user account (standard) or user interaction.  
Successful exploitation of the vulnerability results in unauthorized path or file access via local file or path include attack.  
  
  
Vulnerable Application(s):  
[+] Air Disk v1.9 - ITunes or AppStore (Apple)  
  
Vulnerable Module(s):  
[+] File Upload  
  
Vulnerable Parameter(s):  
[+] filename  
  
Affected Module(s):  
[+] Air Disk Index - (Filename) Listing  
  
  
  
1.2  
A local command injection web vulnerability is detected in the Air Disk Wireless HTTP File Sharing 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 requests to provoke the execution when processing to watch the index listing.  
  
Exploitation of the web vulnerability does not require a privileged application user account (standard) or user interaction.  
Successful exploitation of the vulnerability results unauthorized execution of system specific commands and path requests.  
  
  
Vulnerable Application(s):  
[+] Air Disk v1.9 - ITunes or AppStore (Apple)  
  
Vulnerable Module(s):  
[+] Index  
  
Vulnerable Parameter(s):  
[+] device name - iPad or iPone  
  
Affected Module(s):  
[+] Air Disk Index - (Device Name) Listing  
  
  
  
Proof of Concept:  
=================  
1.1  
The file include vulnerability can be exploited by remote attackers without required user interaction or privileged application user account.

Risk:  
=====  
1.1  
The security risk of the remote file include web vulnerability is estimated as critical.  
  
1.2  
The security risk of the local command injection web vulnerability is estimated as high.
