  Title: Arachni Web Application Scanner Web UI Stored XSS Vulnerability CVE: 2014-5469 Vendor Homepage: http://www.arachni-scanner.com/ Author: Prakhar Prasad 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(&apos;XSS&apos;))   The above comment will roughly translate into: <a href="javascript:alert(&apos;XSS&apos;);">XSS</a>. Hence creating an anchor with user-supplied Javascript content.
