Abstract:
=========
The Vulnerability Laboratory Research Team discovered multiple web
vulnerabilities in the mobile USB Sharp v1.3.4 app for the apple ipad & iphone.
Report-Timeline:
================
2013-02-16: Public Disclosure
Status:
========
Published
Affected Products:
==================
Apple AppStore
Product: USB Sharp - Web Server Application 1.3.4
Exploitation-Technique:
=======================
Remote
Severity:
=========
High
Details:
========
1.1
A local file include web vulnerability via POST request method is detected in
the mobile USB Sharp v1.3.4 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/) when processing to load a manipulated
filename via POST. The execution of the injected path or file request will
occur when the attacker is processing to watch the file dir listing.
Exploitation of the vulnerability requires no user interaction and can be done
without privileged application user account (no password standard).
Successful exploitation of the vulnerability results in unauthorized path or
file access via local file or path include attack.
Vulnerable Application(s):
[+] USB Sharp v1.3.4 - ITunes or AppStore
(Apple)
Vulnerable Module(s):
[+] File Upload (Web Server) [Remote]
Vulnerable Parameter(s):
[+] filename
Affected Module(s):
[+] Filename Dir Index Listing
1.2
A persistent input validation vulnerability is detected in the mobile USB Sharp
v1.3.4 app for the apple ipad & iphone.
The bug allows an attacker (remote) to implement/inject malicious script code
on the application side (persistent) of the app web service.
The vulnerability is located in the index file dir listing module of the
webserver (http://192.168.0.10:41491/) when processing to inject
via POST method manipulated new chxItem parameters. The persistent script code
will be executed out of the main index file dir listing
module when the service is processing to list the new foldername as item.
Exploitation of the vulnerability requires low or medium user interaction
without privileged 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):
[+] USB Sharp v1.3.4 - ITunes or AppStore
(Apple)
Vulnerable Module(s):
[+] Index File Dir Listing
Vulnerable Parameter(s):
[+] Foldername (items > chxItem)
Affected Module(s):
[+] Index Listing
Proof of Concept:
=================
1.1
The local file include web vulnerability can be exploited by remote attackers
without user interaction and without
privileged application user account. For demonstration or reproduce ...
Example:
File > Upload via POST > Tamper Session > Change Filename Value to File or Path
+ Extension > Open Listing > Execution
PoC: (POST)
-----------------------------1337341202721337
Content-Disposition: form-data; name="file";
filename="..%2F..%2F..%2F..%2Fcmd>home>tmp%00<'.JPG"
Content-Type: image/jpg
Note: Encode the request ago to bypass the encoding validation of the input.
(%2F)

1.2
The persistent input validation vulnerability can be exploited by remote
attackers without user interaction and without
privileged application user account. For demonstration or reproduce ...
PoC: Index - Folder Dir Listing
<tbody id="filelist"><tr><td><input name="chxItem" value="[PERSISTENT INJECTED
SCRIPT CODE!]"
onclick="selChkItem(this)" type="checkbox"></td><td><a href="/[PERSISTENT
INJECTED SCRIPT CODE!]%3C?guid=

style="vertical-align:middle;"><img src="/Folder.png"
style="border:0;vertical-align:middle" ;=""></span>%20"><[PERSISTENT INJECTED
SCRIPT CODE!];)" <<="" a=""></td><td></td>
<td>2013-02-10 22:57:54</td><td><input name="commit" type="button"
value="Delete"
onclick="DelegateData('/[PERSISTENT INJECTED SCRIPT
CODE!]','47E79C76-D4C2-4086-B695-3CEE71A6B5F3');"
class='button'

</td></tr></tbody>

Risk:
=====
1.1
The security risk of the local file/path include web vulnerability via POST
request method is estimated as high(+).
1.2
The security risk of the persistent input validation web vulnerability is
estimated as medium.
