Technical Details & Description:
================================
A GET cross site scripting web vulnerability has been discovered in the 
official Netlife Photosuite Pro Content Management System.
A vulnerability allows remote attackers to inject malicious script codes on the 
client-side of the affected web-application.

The vulnerability is located in the `message` value of the 
`sections/prophoto/key.php` file. Remote attackers are able to inject own 
malicious script codes to the client-side of the affected web-application. The 
request method to inject is GET and the attack 
vector is client-side. The attacker inject the payload in the message value to 
execute the code in key.php.

The security risk of the client-side web vulnerability is estimated as medium 
with a cvss (common vulnerability scoring system) count of 3.3. 
Exploitation of the non-persistent cross site scripting web vulnerability 
requires no web-application user account and no user interaction. 
Successful exploitation results in session hijacking, persistent phishings 
attacks, persistent external redirect and malware loads or persistent 
manipulation of affected or connected module context.

Request Method(s):
                                        [+] GET

Vulnerable Module(s):
                                        [+] sections/prophoto/

Vulnerable File(s):
                                        [+] key.php

`message` value in the affected key.php file GET method request.
Filter the input and restrict it by disallowing usage of special chars or 
script code tags to prevent client-side injection attacks.
