Technical Details & Description:

================================
|
||
1.1
|
||
A local file include web vulnerability has been discovered in the official Lazybone Studios WiFi Music v1.0 iOS mobile web-application.
|
||
A 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 File` 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 persistent and
|
||
the request method is POST. The local file/path include execution occcurs in the main music file dir list. The security risk of the local
|
||
file include web vulnerability is estimated as high(+) with a cvss (common vulnerability scoring system) count of 6.7(+)|(-)6.8.
|
||
|
||
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):
|
||
[+] Select File > Upload
|
||
|
||
Vulnerable Parameter(s):
|
||
[+] filename
|
||
|
||
Affected Module(s):
|
||
[+] Music File Dir List (http://localhost:8080/)
|
||
|
||
|
||
|
||
1.2
|
||
An arbitrary file upload web vulnerability has been discovered in the official Lazybone Studios WiFi Music v1.0 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 `upload` (video and music) 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 `ptest.mp3.html.php.js.aspx.mp3`. After the upload the attacker needs to open the file with the path value in the web application.
|
||
He deletes the .mp3 file extension and can access the application with elevated executable 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 7.7(+)|(-)7.8.
|
||
|
||
Exploitation of the arbitrary file upload web vulnerability requires no user interaction or privileged application user account with password.
|
||
Successful exploitation of the vulnerability results in unauthorized file access because of a compromise after the upload of web-shells.
|
||
|
||
Request Method(s):
|
||
[+] [POST]
|
||
|
||
Vulnerable Module(s):
|
||
[+] Select File > Upload
|
||
|
||
Vulnerable Parameter(s):
|
||
[+] filename (multiple extensions)
|
||
|
||
Affected Module(s):
|
||
[+] Music File Dir List (http://localhost:8080/)

Solution - Fix & Patch:
|
||
=======================
|
||
1.1
|
||
The local file include web vulnerability can be patched by a secure parse and encode of the vulnerable filename value in the upload file POST method request.
|
||
Filter and encode also the filename output listing of the index.
|
||
|
||
1.2
|
||
Filter and restrict the file name validation on uploads to prevent arbitrary file upload attacks.
|
||
Implement a secure own exception-handling to restrict and disallow files with multiple extensions.
|
||
Reset the executable rights for html and php codes in the little web-server settings config for /files.
|
||
|
||
|
||
Security Risk:
|
||
==============
|
||
1.1
|
||
The security risk of the local file include web vulnerability is estimated as high(-).
|
||
|
||
1.2
|
||
The security risk of the arbitrary file upload web vulnerability is estimated as high(+).
