Technical Details & Description:
==============================
1.1
A local file include web vulnerability has been discovered in the official Savy Soda - WiFI HD v7.3.0 iOS mobile web-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 mobile web-application.
The web vulnerability is located in the `filename` value of the `upload` (submit file) module. Remote attackers are able to inject
own files with malicious `filename` values in the `upload` POST method request to compromise the mobile web-application. The local
file/path include execution occcurs in the index file/folder list context next to the vulnerable filename value. The attacker is able
to inject the local file request by usage of the available `wifi interface` for file exchange/share.
Remote attackers are also able to exploit the filename validation issue in combination with persistent injected script codes to execute
different local malicious attacks requests. The attack vector is on the application-side of the wifi service and the request method to
inject is POST.
The security risk of the local file include web vulnerability is estimated as high with a cvss (common vulnerability scoring system)
count of 6.9. Exploitation of the local file include web vulnerability requires no privileged web-application user account or user interaction.
Successful exploitation of the local file include web vulnerability results in mobile application or connected device component compromise.
Request Method(s):
[+] [POST]
Vulnerable Service(s):
[+] WiFi HD v7.3.0
Vulnerable Module(s):
[+] Upload > Submit
Vulnerable Parameter(s):
[+] filename
Affected Module(s):
[+] Index File/Folder Dir Listing (http://localhost/)
1.2
A directory traversal web vulnerability has been discovered in the official Savy Soda - WiFI HD v7.3.0 iOS mobile web-application.
The issue allows remote attackers to include own path directory values to unauthorized request a system/device path or file.
The issue is located in the `Create New Folder` function with the vulnerable `Enter folder name` input. Attackers are able to include
own local path requests to compromise the application path itself or to unauthorized request local device files. The attack vector of
the issue is on the application-side and the request method to implement is POST. The application-side execution occurs on top of the
index next to the path directory listing of /home.
The security risk of the directory traversal web vulnerability is estimated as high with a cvss (common vulnerability scoring system)
count of 6.4. Exploitation of the directory traversal web vulnerability requires no privileged web-application user account or user interaction.
Successful exploitation of the path traversal web vulnerability results in mobile application or connected device component compromise.
Request Method(s):
[+] [POST]
Vulnerable Service(s):
[+] WiFi HD v7.3.0
Vulnerable Module(s):
[+] Create New Folder
Vulnerable Input(s):
[+] Enter folder name
Affected Module(s):
[+] Index Path Dir Listing on top (http://localhost/)
1.3
A local command/path injection web vulnerabilities has been discovered in the official Savy Soda - WiFI HD v7.3.0 iOS mobile web-application.
The vulnerability allows attackers to inject local commands via vulnerable system values to compromise the apple mobile iOS application.
The vulnerability is located in the vulnerable `devicename` value of the `File Dir Index` module. Local attackers are able to inject own
malicious system specific commands or path value requests in the vulnerable `devicename` value. The execution of the local command inject
occurs in the `File Dir Index` module of the wifi hd v7.3.0 mobile application. The attacker is able to manipulate the settings module of the
application by preparing to change the local devicename. The encoding of the vulnerable values in the index module is broken and allows an
attacker to inject own commands successfully.
The attack vector is located on the application-side and the injection requires physical device access or a local low privileged user account.
Local attackers are also able to exploit the filename validation issue in combination with persistent injected script codes to execute different
types of malicious attack requests.
The security risk of the local command/path inject vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 6.2.
Exploitation of the command/path inject vulnerability requires a low privileged iOS device account with restricted access and no user interaction.
Successful exploitation of the vulnerability results in unauthorized execution of system specific commands and unauthorized path value requests to
compromise the mobile iOS application or the connected device components.
Request Method(s):
[+] [POST]
Vulnerable Module(s):
[+] Application Header
Vulnerable Parameter(s):
[+] devicename
Affected Module(s):
[+] Index File Dir Listing - Index Header
1.4
A cross site request forgery web vulnerability has been discovered in the official Savy Soda - WiFI HD v7.3.0 iOS mobile web-application.
The issue allows to execute own script codes through application functions by client-side manipulated cross site requests in interaction
with a not expired user session.
The issue is located in the `delete` function of the mobile web-application. The delete function has no restriction and uses only a not
secure GET method request. Attackers can prepare a website with speical crafted links to force an user to delete all the files in the
exchange directory service. The attack vector of the issue is on the client-side and the request method to execute is GET.
The security risk of the cross site request forgery vulnerability is estimated as low with a cvss (common vulnerability scoring system) count of 1.9.
Exploitation of the client-side vulnerability requires no privileged iOS device account but medium or high user interaction. Successful exploitation
of the vulnerability results in the delete of all files in the mobile application service.
Request Method(s):
[+] [GET]
Vulnerable Parameter(s):
[+] DEL!
Affected Module(s):
[+] Index File Dir Listing

Solution - Fix & Patch:
=======================
1.1
The local file include web vulnerability can be patched by a secure parse of the filename value in the submit to upload function of the wifi service.
Encode also the filename output listing to prevent further file include attacks via upload.
1.2
The directory traversal can be patched by a special restriction in the requested path value of the web-server. Especially when processing to
request the home/path value or by creating a new folder.
Restrict the input and disallow script code tags as chars, double quotes and slash to prevent the attack.
1.3
The local command inject web vulnerability can be patched by a secure parse and encode of the vulnerable device name information.
Restrict the devicename output and filter wrong inputs to prevent further command injection attacks.
1.4
The cross site request forgery issue can be patched by a secure restriction of the DEL! value.
Setup access roles to ensure that an user account can not delete all directory items.
Security Risk:
==============
1.1
The security risk of the local file include vulnerability in the upload > submit function is estimated as high.
1.2
The security risk of the directory traversal web vulnerability in the path&directory listing is estimated as high.
1.3
The security risk of the local command inject web vulnerability is estimated as high(-).
1.4
The security risk of the client-side cross site request forgery vulnerability is estimated as low(+).
