  • NTLM Authentication Issues in 1.7.33

    Our Red Team discovered a bug in webapps that utilize NTLM authentication. The NTLM auth requests were not being properly sent from Burpsuite 1.7.33 and access was consistently denied with working credentials. Taking Burp out of the chain resulted in successful authentication in Chrome, Explorer, or Firefox. The NTLM authentication was found to be working with Zap as the intercepting proxy too.

  • Does Burp try to send unsent files.

    A server team is reporting that it is still receiving attack strings and file upload attacks from my scan even though I stopped scanning more than one week ago. Is it possible that Burp (or my OS) is still trying to send unsent attacks when I open it back up? Does it have a queue of unsent attacks that would go out even though scanner is paused? This particular scan was very resource intensiv...
