Hi, testing again on zero.webappsecurity.com Burp ( 2.1.04 ) is missing the remote file inclusion at /help.html
After forcing an audit on the specific URL Burp was able to identify the Out of band resource loading that was missed on the initial website crawl and audit scan.
Thanks for this report. We’ve replicated this behavior and created a ticket to investigate further. We’ll update this thread when we have something to share.
Please let us know if you need any further assistance.
