Technical Details & Description:  
================================  
Multiple persistent input validation web vulnerabilities has been discoveredin the Webile v1.0.1 Wifi mobile android web 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 web vulnerabilities are located in the send and add function. Remote attackers are able to inject own malicious  
script codes to the new_file_name and i parameter post method request to provoke a persistent execution of the malformed content.  
  
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 Parameter(s):  
[+] new_file_name  
[+] i  
  
  
Proof of Concept (PoC):  
=======================  
The persistent input validation web vulnerabilities can be exploited by remote attackers without user account and with low user interaction.  
For security demonstration or to reproduce the persistent cross site web vulnerability follow the provided information and steps below to continue.
