Technical Details & Description:
|
||
================================
|
||
1.1
|
||
A local file include web vulnerability has been discovered in the official OnDemandWorld Wireless Drive v1.1.0 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 web-application or mobile device.
|
||
|
||
The web vulnerability is located in the `filename` value of the `Upload file` module. Remote attackers are able to inject own files with malicious
|
||
`filename` value in the upload POST method request to compromise the mobile web-application. The attack vector is persistent and the request
|
||
method is POST. The local file/path include execution occcurs in the main file dir list. The security risk of the local file include web vulnerability
|
||
is estimated as high(+) with a cvss (common vulnerability scoring system) count of 6.7(+)|(-)6.8.
|
||
|
||
Exploitation of the local file include web vulnerability requires no user interaction but a privileged web-application user account with low user auth.
|
||
Successful exploitation of the local file include web vulnerability results in mobile application or connected device component compromise.
|
||
|
||
Request Method(s):
|
||
[+] [POST]
|
||
|
||
Vulnerable Module(s):
|
||
[+] Upload file
|
||
|
||
Vulnerable Parameter(s):
|
||
[+] filename
|
||
|
||
Affected Module(s):
|
||
[+] Upload > Menu File Dir List (http://localhost:4096)
|
||
|
||
|
||
|
||
1.2
|
||
A local command/path injection web vulnerabilities has been discovered in the official OnDemandWorld Wireless Drive v1.1.0 iOS mobile web-application.
|
||
A command inject vulnerability allows attackers to inject local commands via vulnerable system values to compromise the apple mobile iOS application.
|
||
|
||
The vulnerability is located in the vulnerable `[foldername]` value of the wifi file dir list module. Local attackers are able to inject own malicious
|
||
system specific commands or path value requests in the vulnerable foldername value. The injection requires a active sync with the wifi app stored folders.
|
||
The execution of the local command inject via foldername value on sync occurs in the file dir index list of the main upload path. The security risk of
|
||
the local command/path inject vulnerability is estimated as high(-) with a cvss (common vulnerability scoring system) count of 5.6(+)|(-)5.7.
|
||
|
||
Exploitation of the command/path inject vulnerability requires a low privileged iOS device account with restricted access and no user interaction.
|
||
Successful exploitation of the vulnerability results in unauthorized execution of system specific commands and unauthorized path value requests to
|
||
compromise the mobile iOS application or the connected device components.
|
||
|
||
Request Method(s):
|
||
[+] Sync
|
||
|
||
Vulnerable Parameter(s):
|
||
[+] foldername (path value)
|
||
|
||
Affected Module(s):
|
||
[+] Index- File Dir Listing
|
||
[+] Sub Folder/Category - File Dir Listing
|
||
|
||
|
||
Proof of Concept (PoC):
|
||
=======================
|
||

Solution - Fix & Patch:
|
||
=======================
|
||
1.1
|
||
The local command inject web vulnerability can be patched by a secure parse and encode of the vulnerable filename value in the upload file POST method request.
|
||
Encode also the filename index listing to prevent execution of malicious commands, injection of script codes or file include attacks.
|
||
|
||
1.2
|
||
The local command inject web vulnerability can be patched by a secure parse and restriction of the rename and foldername value in the wifi app.
|
||
Encode also the output index list were the folders will become visible after the sync.
|
||
|
||
|
||
Security Risk:
|
||
==============
|
||
1.1
|
||
The security risk of the local file include web vulnerability in the wifi exchange interface is estimated as high(+).
|
||
|
||
1.2
|
||
The local command inject vulnerability in the foldername value via sync is estimated as high(-).
