Author Homepage: https://prakharprasad.com  
Reference: https://github.com/Arachni/arachni-ui-web/issues/71  
Affected Version: Arachni v0.4.7/WebUI v0.4.4 (possibly in lower versions  
too)  
Date: August 17th 2014  
Tested on: Arachni v0.4.7/WebUI v0.4.4 - Ubuntu 14.04  
  
  
Details  
=======  
  
This is an authenticated Stored XSS, hence the user needs to be logged in  
to exploit this issue.  
  
A malicious user (admin/regular) can initiate a website scan in the Arachni  
Web UI. After initiating the scan, there is an option of users to comment  
onto it (with Markdown formatting). However using Markdown the malicious  
user can craft a link that will execute arbitrary Javascript once clicked.  
  
The proof of concept XSS comment: [XSS](javascript:alert('XSS'))  
  
The above comment will roughly translate into: <a  
href="javascript:alert('XSS');">XSS</a>. Hence creating an anchor with  
user-supplied Javascript content.
