Remote


Severity Level:
===============
Low


Technical Details & Description:
================================
A client-side cross site scripting web vulnerability has been discovered in the official  Virtual Freer v1.58 web-application.
The web vulnerability allows to inject own malicious script codes to the client-side of the vulnerable web-application module.

The client-side cross site scripting vulnerability is located in the `direct.php` value of the `qty` file GET method request.
Remote attackers are able to inject client-side script codes to the qty value of the direct.php file GET method request to 
compromise session data. The attack vector of the issue is non-persistent and the request method to inject is GET (client-side).

The security risk of the web vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 3.2. 
Exploitation of the non-persistent web vulnerability requires no privileged web application user account and low or medium user interaction. 
Successful exploitation of the vulnerability results in session hijacking, non-persistent phishing, non-persistent external redirects, 
non-persistent load of malicious script codes or non-persistent web module context manipulation.

Request Method(s):
				[+] GET

Vulnerable Module(s):
				[+] Adobe - Edex

Vulnerable Section(s):
				[+] search/global/

Vulnerable Parameter(s):
				[+] keyword-holder (keyword)


Proof of Concept (PoC):
=======================
The client-side cross site vulnerability can be exploited by remote attackers without privileged web-application user account and with low user interaction.
