Technical Details & Description:
================================
1.1
A local file include web vulnerability has been discovered in the HD Video
Player v2.5 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 `file uploader`
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):
[+] File Uploader
Vulnerable Parameter(s):
[+] filename
Affected Module(s):
[+] Index File Dir Listing
(http://localhost:8083/ or http://localhost:20000)
1.2
An arbitrary file upload web vulnerability has been discovered in the HD Video
Player v2.5 iOS mobile web-application (wifi).
The arbitrary file upload issue allows remote attackers to upload files with
multiple extensions to bypass the system validation and compromise the
web-server.
The vulnerability is located in the filename value of the `file uploader`
module. Remote attackers are able to upload a php or js web-shell by a rename
of the
filename with multiple extensions in the upload POST method request. The
attacker uploads for example a web-shell with the following name and extension
`pentest.png.html.php.js.aspx.html.png`. After the upload the attacker needs to
open the file in the wifi web-application interface. He deletes the .png file
extension and can access the webshell with elevated access rights to execute.
The security risk of the arbitrary file upload web vulnerability is estimated
as high with a cvss (common vulnerability scoring system) count of 7.3.
Exploitation of the arbitrary file upload web vulnerability requires no user
interaction or privileged web-application user account with password.
Successful exploitation of the arbitrary file upload vulnerability results in
unauthorized file access (aap/device) and compromise of http web-server.
Request Method(s):
[+] [POST]
Vulnerable Module(s):
[+] Upload
Vulnerable Parameter(s):
[+] filename (multiple extensions)
Affected Module(s):
[+] Index File Dir Listing
(http://localhost:8083/ or http://localhost:20000)
Proof of Concept (PoC):
