Technical Details & Description:
================================
A client-side cross site scripting vulnerability has been discovered in the official PaulPrinting (v2018) cms 
web-application.
Remote attackers are able to manipulate client-side requests by injection of malicious script code to compromise user 
session data.

The client-side cross site scripting web vulnerability is located in the search input field with the insecure validated 
q parameter
affecting the delivery module. Remote attackers are able to inject own malicious script code to the search input to 
provoke a client-side
script code execution without secure encode. The request method to execute is GET and the attack vector is 
non-persistent.

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):
[+] /account/delivery

Vulnerable Input(s):
[+] Search

Vulnerable Parameter(s):
[+] q

Affected Module(s):
[+] /account/delivery
[+] Delivery Contacts


Proof of Concept (PoC):
=======================
The non-persistent xss web vulnerability can be exploited by remote attackers with low privileged user account and 
medium user interaction.
For security demonstration or to reproduce the vulnerability follow the provided information and steps below to 
continue.
