Technical Details & Description:
================================
1.1
A persistent script code injection web vulnerability has been discovered
in the official Playable v9.18 apple ios mobile application.
The vulnerability allows remote attackers to inject own malicious
persistent script codes to the application-side for manipulation.
The vulnerability is located in the filename parameter of the upload
module. Attackers with wifi access are able to perform uploads
with malicious script code to manipulation the mobile application ui.
The request method to inject is POST and the attack vector of
the vulnerability is persistent. Attackers are able to inject html and
javascript codes to comrpomise the mobile wifi web-application.
The injection point is the upload form on localhost:8881 and the
execution occurs on localhost:80 with the visible ui listing.
Successful exploitation of the vulnerability results in session
hijacking, persistent phishing attacks, persistent external redirects
to malicious source and persistent manipulation of affected mobile
application modules.
Request Method(s):
[+] POST
Vulnerable Function(s):
[+] upload
Vulnerable Parameter(s):
[+] filename
1.2
An arbitrary file upload web vulnerability has been discovered in the
official Playable v9.18 apple ios mobile application.
The arbitary file upload vulnerability allows remote attackers to upload
malicious files to compromise the mobile application.
The vulnerability is located in the filename parameter of the upload
module. Attackers with wifi access are able to perform
uploads with malicious file extions to bypass the parse function. In a
second step the attacker requests the local file to
execute the malicious content on the local web-server. The request
method to inject is POST and the attack vector of the
vulnerability is located on the application-side. The injection point is
the upload form on localhost:8881. The execution
point becomes visible by a request the localhost:80/vid/[filename] path
with the uploaded file content. The is present
because of a missing file parse and insecure upload handling on file
extensions. As well the local web-server can be
reconfigured to provide more security on user interactions.
Successful exploitation of the arbitrary file upload vulnerability
results in a compromise of the local ios mobile application.
Request Method(s):
[+] POST
Vulnerable Function(s):
[+] upload
Vulnerable Parameter(s):
[+] filename
Affected Module(s):
[+] /vid/
Proof of Concept (PoC):

For security demonstration or to reproduce the vulnerability follow the
provided information and steps below to continue.
Manual steps to reproduce the vulnerability ...
1. Install the ios application
(https://apps.apple.com/us/app/playable-the-full-hd-media-player/id502405034)
2. Start the ios application on your local ios device
3. Start the wifi share service in the application ui
4. Open the web-browser
5. Tamper the http requests
6. Prepare to upload any file and press the upload button
7. Inject as filename any html/js script code payload
8. Continue to transmit the POST method request
9. The file executes on the index listing on port 8881
(http://localhost:8881/index.html)

1.2
the arbitrary file upload vulnerability can be exploited by local
attackers with wifi network access without user interaction.
For security demonstration or to reproduce the vulnerability follow the
provided information and steps below to continue.
Manual steps to reproduce the vulnerability ...
1. Install the ios application
(https://apps.apple.com/us/app/playable-the-full-hd-media-player/id502405034)
2. Start the ios application on your local ios device
3. Start the wifi share service in the application ui
4. Open the web-browser
5. Tamper the http requests
6. Prepare a js file with malicious test content
7. Extend the file name with .jpg
Note: The upload mechanism does not parse or checks for multiple
extensions on file uploads
8. Upload the file by pushing the Upload File button
9. Open the url in the default /vid/ folder and remove the .jpg extension
10. The simple js executes in the scripting engine when opening
11. Successful reproduce of the arbitrary file upload vulnerability!
Note: Using the ftp you can perform to create the file via console
ftp://localhost (read/write permissions)

Solution - Fix & Patch:
=======================
1.1
The vulnerability can be resolved by a restriction and parse of the
filename parameter. Disallow special chars and restrict inputs.
Encode also the output locations to ensure nobody is able to execute
script code in the main file listing.
1.2
Parse the filename for multiple extensions and prevent that attackers
open specific dangerous file extensions that could
compromise the local application path.
Security Risk:
==============
1.1
The security risk of the script code injection web vulnerability in the
mobile ios application is estimated as high.
1.2
The security risk of the arbitrary file upload vulnerability in the
mobile ios application is estimated as high.
