  • Possible bug: Missing hosts in site map in branch 2.x

    I think I spotted a bug on burp 2.x which wasn't there on the previous branch. It might be reproductible with the following steps (hopefully): - Setup a scope - Burp ask if you want to "limit item sent to proxy history to the scope" : answer yes - Change the scope to add a new host - Reenable proxy history for everything - Browse the new host added in to the scope: Resul...

  • Crawl not finding items

    I have a directory with a known file, e.g. This appears as a grey item from the passive crawl in the Site Map under the Target tab, and the Response tab under Content is blank (because the resource hasn't actually been requested yet). If I directly browse to the file, it loads normally, appears in Proxy tab, however under Site Map it's still greye...

  • Scanning REST APIs with Burp Enteprise

    We regularly scan RESTful APIs using Burp Suite Professional together with Postman. Once we have navigated all of the API's endpoints with Postman, we unleash the Burp scan. As long as the API endpoints don't change we run Burp periodically and manually using the same sitemap. We would like to know if there is a way to feed a Burp Suite Professional project into Burp Enterprise, in order...

  • Scan consuming all available memory

    I'm currently running a scan on Burp Suite Professional v2.0.13beta and all available memory (2.99GB) is being used up by the scan. I've even throttled the scan down to 2 consecutive threads only and the memory is still being used up.
