Technical Details & Description:
|
||
================================
|
||
1.1
|
||
A local file include web vulnerability has been discovered in the officialBluetooth Photo/Video/Music/Contact Share Pro v2.0 iOS mobile application.
|
||
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 `Select File to Upload` function POST method request. Remote attackers are
|
||
able to inject own files with malicious `filename` to compromise the mobile application. The attack vector is persistent and the request
|
||
method is POST. The local file/path include execution occcurs in the main index file dir list of the path section after the regular upload.
|
||
The security risk of the local file include web vulnerability is estimated as high(+) with a cvss (common vulnerability scoring system)
|
||
count of 7.4(+)|(-)7.5.
|
||
|
||
Exploitation of the local file include web vulnerability requires no user interaction or privileged web-application user account with password.
|
||
Successful exploitation of the local 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):
|
||
[+] Index File Dir List (http://localhost:8080)
|
||
|
||
|
||
|
||
1.2
|
||
An arbitrary file upload web vulnerability has been discovered in the officialBluetooth Photo/Video/Music/Contact Share Pro v2.0 iOS mobile 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 images) 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 `image.gif.jpg.html.js.aspx.jpg`. After the upload the attacker needs to open the file in the web application. He deletes the .jpg &
|
||
.gif 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 6.1(+)|(-)6.2.
|
||
|
||
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):
|
||
[+] Index File Dir List (http://localhost:8080/)
|
||
|
||
