Product: My.WiFi USB Drive - iOS Mobile (Web-Application) 1.0

Exploitation Technique:

Severity Level:

Technical Details & Description:
A local file include web vulnerability has been discovered in the official My.WiFi USB Drive v1.0 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 mobile web-application.

The web vulnerability is located in the `filename` value of the `Upload Files` module. Remote attackers are able to inject own files with malicious
`filename` values in the `Upload Files` POST method request to compromise the mobile web-application. The local file/path include execution occcurs in
the index file dir listing of the wifi interface. The attacker is able to inject the local file include request by usage of the `wifi interface`
in connection with the vulnerable upload files POST method request.

Remote attackers are also able to exploit the filename issue in combination with persistent injected script codes to execute different malicious
attack requests. The attack vector is located on the application-side of the wifi service and the request method to inject is POST.

The security risk of the local file include 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 user interaction or privilege web-application user account.
Successful exploitation of the local file include vulnerability results in mobile application compromise or connected device component compromise.

Request Method(s):
[+] [POST]

Vulnerable Module(s):
[+] Upload Files

Vulnerable Parameter(s):
[+] filename

Affected Module(s):
[+] Index File Dir Listing (http://localhost/)

Proof of Concept (PoC):
The file include web vulnerability can be exploited by remote attackers without privilege web-application user account or user interaction.

Solution - Fix & Patch:
The vulnerability can be patched by a secure validation of the filename value in the upload POST method request. Restrict the filename input and
disallow special chars. Ensure that not multiple file extensions are loaded in the filename value to prevent arbitrary file upload attacks.
Encode the output in the file dir index list with the vulnerable name value to prevent application-side script code injection attacks.

Security Risk:
The security risk of the local file include web vulnerability in the My.WiFi USB Drive app is estimated as high. (CVSS 7.1)
