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.
