Severity:
=========
Medium


Details:
========
A persistent input validation web vulnerability is detected in the official 
Taxi Monger v2.6.2 Android (v2.3.3) Mobile Application (Google - PlayStore).
The vulnerability allows remote attackers to inject own malicious persistent 
(application-side) script codes to compromise the android application or device.

The persistent input validation web vulnerability is located in the username 
input field when processing to inject malicious script codes as name.
Attackers can inject own malicious script codes to execute the context 
persistent from the index listing. To inject the script code the remote 
attacker 
do not need to bypass the basic validation of the application for successful 
exploitation.

Exploitation of the persistent web vulnerability requires low user interaction 
and a low privilege application user account. Successful exploitation of the 
persistent input validation web vulnerability results in persistent session 
hijacking, persistent web phishing, persistent external redirects or persistent 
module context manipulation.


Vulnerable Module(s):
                                [+] Registration

Vulnerable Input Fields(s):
                                [+] Username

Vulnerable Parameter(s):
                                [+] name (context)

Affected Module(s):
                                [+] Index and Profile Listing


Proof of Concept:
=================
The persistent script coe injection web vulnerability can be exploited by 
remote attackers with low user interaction and low privilege 
application user account. For demonstration or reproduce ...

XSS (JS) PoC:

<Script Language='Javascript'>
<!--
document.write(unescape('%3C%69%6D%61%67%65%20%73%72%63%3D%68%74%74%70%3A%2F%2F%76%75%6C%6E%2D%6C%61%62
%2E%63%6F%6D%20%6F%6E%65%72%72%6F%72%3D%61%6C%65%72%74%28%27%69%73%6D%61%69%6C%6B%61%6C%65%65%6D%27%29%20%2F%3E'));
//-->
</Script>


Solution:
=========
Restrict the username and name input field and parse the input with a secure 
encoding or filter.
Encode and parse the output listing and profile site to prevent persistent 
script code executions from the main application module.


Risk:
=====
The security risk of the persistent input validation web vulnerability is 
estimated as medium(+)|(-)high.
