Technical Details & Description:
|
||
================================
|
||
1.1
|
||
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` 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 on the application-side
|
||
of the wifi service and the request method to inject is POST. The local file/path include execution occcurs in the index file dir list of
|
||
the upload path. Attackers are also able to exploit the filename validation issue in combination with persistent injected script codes to
|
||
execute different local malicious requests. The security risk of the local file include web vulnerability is estimated as high(+) with a
|
||
cvss (common vulnerability scoring system) count of 6.8(+)|(-)6.9.
|
||
|
||
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):
|
||
[+] Search/Select File > Upload
|
||
|
||
Vulnerable Parameter(s):
|
||
[+] filename
|
||
|
||
Affected Module(s):
|
||
[+] Index File Dir List (http://localhost:8080)
|
||
|
||
|
||
|
||
1.2
|
||
An arbitrary file upload web vulnerability has been discovered in the official iShare - Your moving libarary iOS mobile web-application.
|
||
The arbitrary file upload issue allows remote attackers to upload files with multiple extensions to bypass the web-server or system validation.
|
||
|
||
The vulnerability is located in the POST method request of the `Upload` module. Remote attackers are able to upload a php or js web-shells by
|
||
renaming the file with multiple extensions to bypass the file restriction mechanism. The attacker uploads for example a web-shell with the following
|
||
name and extension `test.jpg.html.php.asp.html.jpg`. After the upload the attacker needs to open the file in the web application. He deletes the .jpg
|
||
file extension and can access the application with elevated access rights. The security risk of the arbitrary file upload web vulnerability is estimated
|
||
as high with a cvss (common vulnerability scoring system) count of 7.1(+)|(-)7.2.
|
||
|
||
Exploitation of the arbitrary file upload web vulnerability requires no user interaction or privileged application user account with password.
|
||
Successful exploitation of the arbitrary file upload web vulnerability results in unauthorized file access and system compromise.
|
||
|
||
Request Method(s):
|
||
[+] [POST]
|
||
|
||
Vulnerable Module(s):
|
||
[+] Select File > Upload
|
||
|
||
Vulnerable Parameter(s):
|
||
[+] filename (multiple extensions)
|
||
|
||
Affected Module(s):
|
||
[+] Index File Dir List (http://localhost:8080)
|
||
|
||

||
Proof of Concept (PoC):
|
||
=======================
