# Exploit Title: Active Super Shop CMS v2.5 - HTML Injection Vulnerabilities
References (Source): https://www.vulnerability-lab.com/get_content.php?id=2278
Release Date:
2023-07-04
Vulnerability Laboratory ID (VL-ID): 2278

Common Vulnerability Scoring System: 5.4

Product & Service Introduction:
===============================
https://codecanyon.net/item/active-super-shop-multivendor-cms/12124432


Abstract Advisory Information:
==============================
The vulnerability laboratory core research team discovered multiple html injection vulnerabilities in the Active Super Shop Multi-vendor CMS v2.5 web-application.


Affected Product(s):
====================
ActiveITzone
Product: Active Super Shop CMS v2.5 (CMS) (Web-Application)


Vulnerability Disclosure Timeline:

Discovery Status:
=================
Published


Exploitation Technique:
=======================
Remote


Severity Level:
===============
Medium


Authentication Type:
====================
Restricted Authentication (User Privileges)


User Interaction:
=================
Low User Interaction


Disclosure Type:
================
Responsible Disclosure


Technical Details & Description:
================================
Multiple html injection web vulnerabilities has been discovered in the official Active Super Shop Multi-vendor CMS v2.5 web-application.
The web vulnerability allows remote attackers to inject own html codes with persistent vector to manipulate application content.

The persistent html injection web vulnerabilities are located in the name, phone and address parameters of the manage profile and products branding module.
Remote attackers with privileged accountant access are able to inject own malicious script code in the name parameter to provoke a persistent execution on
profile view or products preview listing. There are 3 different privileges that are allowed to access the backend like the accountant (low privileges), the
manager (medium privileges) or the admin (high privileges). Accountants are able to attack the higher privileged access roles of admins and manager on preview
of the elements in the backend to compromise the application. The request method to inject is post and the attack vector is persistent located on the application-side.

Successful exploitation of the vulnerabilities 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 Module(s):
[+] Manage Details

Vulnerable Parameter(s):
[+] name
[+] phone
[+] address

Affected Module(s):
[+] manage profile
[+] products branding


Proof of Concept (PoC):
=======================
The html injection web vulnerabilities can be exploited by remote attackers with privileged accountant access 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.

Solution - Fix & Patch:
=======================
Disallow inseration of html code for input fields like name, adress and phone. Sanitize the content to secure deliver.


Security Risk:
==============
The security risk of the html injection web vulnerabilities in the shopping web-application are estimated as medium.
