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
Low
PR
The attacker requires privileges that provide basic capabilities that are typically limited to settings and resources owned by a single low-privileged user. Alternatively, an attacker with Low privileges has the ability to access only non-sensitive resources.
Scope
Unchanged
S
An exploited vulnerability can only affect resources managed by the same security authority. In the case of a vulnerability in a virtualized environment, an exploited vulnerability in one guest instance would not affect neighboring guest instances.
Confidentiality
High
C
There is total information disclosure, resulting in all data on the system being revealed to the attacker, or there is a possibility of the attacker gaining control over confidential data.
Integrity
High
I
There is a total compromise of system integrity. There is a complete loss of system protection, resulting in the attacker being able to modify any file on the target system.
Availability
High
A
There is a total shutdown of the affected resource. The attacker can deny access to the system or data, potentially causing significant loss to the organization.

Product & Service Introduction:
===============================
Magento is an open source e-commerce web application that was launched on March 31, 2008 under the name Bento. It was developed
by Varien (now Magento, a division of eBay) with help from the programmers within the open source community but is now owned
solely by eBay Inc. Magento was built using parts of the Zend Framework. It uses the entity-attribute-value (EAV) database model
to store data. In November 2013, W3Techs estimated that Magento was used by 0.9% of all websites.
Our team of security professionals works hard to keep Magento customer information secure. What`s equally important to protecting

Abstract Advisory Information:
==============================
The Vulnerability Laboratory Core Research Team discovered SSRF/XSPA vulnerability in the official Magento Commerce online service web-application.

====================
Ebay Inc.
Product: Magento - Web Application Service 2015 Q4
Exploitation Technique:
=======================
Remote
Severity Level:
===============
Medium
Technical Details & Description:
================================
SSRF/XSPA vulnerability has been discovered in the official Magento Commerce online service web-application.
The vulnerability allows remote attackers to perform malicious server-side requests to compromise the computer system or to
gain unauthorized access to data or sensitive information. The XSPA & SSRF allows to use the process functionality of the
magento engine as port scanner for the local or any random remote machine in the same network. The issue is the first documented
xspa and ssrf issue in the magento service web-applications.
The security risk of the vulnerability is estimated as medium with a cvss (common vulnerability scoring system) count of 4.7.
Exploitation of the ssrf/xspa vulnerability requires a privileged web-application user account and no user interaction.
Successful exploitation of the issue can result in web-server or web-application compromise or unauthorized malicious interactions.
Proof of Concept (PoC):
=======================
Remote attackers are able to perform a local scan on the protected web-server firewall to magento.com and magentocommerce.com

Solution - Fix & Patch:
=======================
The vulnerability has been resolved as bug bounty issue by the magento security team in 2017.
Security Risk:
==============
The security risk of the ssrf/xspa web vulnerability that allows to scan the infrastructure behind the firewall is estimated as medium (CVSS 4.7).
