The vulnerable system is bound to the network stack and the set of possible attackers extends beyond the other options listed below, up to and including the entire Internet. Such a vulnerability is often termed “remotely exploitable” and can be thought of as an attack being exploitable at the protocol level one or more network hops away (e.g., across one or more routers). An example of a network attack is an attacker causing a denial of service by sending a specially crafted TCP packet across a wide area network (e.g., CVE-2004-0230).
Attack Complexity
Low
AC
The attacker must take no measurable action to exploit the vulnerability. The attack requires no target-specific circumvention to exploit the vulnerability. An attacker can expect repeatable success against the vulnerable system.
Privileges Required
High
PR
The attacker requires privileges that provide significant (e.g., administrative) control over the vulnerable system allowing full access to the vulnerable system’s settings and files.
Scope
S
An exploited vulnerability can affect resources beyond the security scope managed by the security authority that is managing the vulnerable component. This is often referred to as a 'privilege escalation,' where the attacker can use the exploited vulnerability to gain control of resources that were not intended or authorized.
Confidentiality
Low
C
There is some impact on confidentiality, but the attacker either does not gain control of any data, or the information obtained does not have a significant impact on the system or its operations.
Integrity
Low
I
Modification of data is possible, but the attacker does not have control over what can be modified, or the extent of what the attacker can affect is limited. The data modified does not have a direct, serious impact on the system.
Availability
None
A
There is no impact on the availability of the system; the attacker does not have the ability to disrupt access to or use of the system.

DefenseCode Security Advisory
Magento Multiple Stored Cross-Site Scripting Vulnerabilities
Advisory ID: DC-2018-03-002
Advisory Title: Magento Multiple Stored Cross-Site Scripting Vulnerabilities
Advisory URL: http://www.defensecode.com/advisories.php
Software: Magento
Version: Magento 2.0 prior to 2.0.18
Vendor Status: Vendor contacted, vulnerability fixed
Release Date: 06/03/2018
Risk: MEDIUM
1. General Overview
===================
During the security audit of Magento Open Source 2 multiple medium
risk stored cross-site scripting vulnerabilities were discovered that
could lead to administrator account takeover, putting the website
customers and their payment information at risk.
2. Software Overview
====================
Magento is an ecommerce platform built on open source technology
which provides online merchants with a flexible shopping cart system,

3. Vulnerability Description
============================
During the security analysis of Magento Open Source 2 prior to 2.0.18
it was discovered that the application returns unescaped and
unsanitized user/customer controlled input on direct requests to
several application URLs.
User/customer controlled information such as customer first and last
name, street address, city, company, shipping and billing information
are unsanitized and unescaped in an output resulted from a direct
request to the following url:
http://website.com/admin/mui/index/render/?namespace=customer_listing&isAjax=true
User/customer first and last name information is unsanitized and
unescaped in an output resulted from a direct request to the
following urls:
http://website.com/admin/mui/index/render/?namespace=customer_online_grid&isAjax=true
http://website.com/admin/mui/index/render/?namespace=sales_order_invoice_grid&isAjax=true
http://website.com/admin/mui/index/render/?namespace=sales_order_grid&isAjax=true
The application will return a text/html response with a json-formatted
content. All aforementioned user-controlled input is prone to stored
cross-site scripting.
The prerequisite for this attack is that the Add Secret Key to URLs
option is disabled. Secret keys are an additional anti-CSRF measure in
Magento, with form keys being the primary measure (that can not be
disabled). In a team setting this option is often disabled in order
to be able to to pass admin links to coleagues, tickets, chat, etc.
4. Solution
===========
Vendor fixed the reported security issues and released a new version.
All users are strongly advised to update to the latest available
version.
