  • Cross-site scripting (reflected) Change?

    Cross-site scripting (reflected) now shows as an informational instead of a high finding after the .16 update. Is that supposed to be the case?

I soon realized that burpsuite was hitting the 15GB mark for memory consumption. As soon as I saved my data and closed down burpsuite. My memory usage went back down to about 1.5GB. So, I am now wonderi...

  • Smart Card not working over Remote Desktop

    We use ActivClient on our local and remote machines for Smart Card authentication. This works fine with IE and Firefox, both local and remote. When Burp is run on the remote machine, it accepts the pin code and appears to work, but never shows any certificates. Technical details that may matter: Remote host is 32-bit Running jre1.8.0_112 using acpkcs211.dll as the library Local host is ...

  • Blank page displayed in Firefox when requesting websites behind corporate firewall

    Hi, As the topic says, the browser (Firefox) simply shows a blank page when requesting websites hosted behind our corporate firewall (but not on same network). The behavior is quite strange considering the following: 1) "No proxy for" is empty. 2) This can be reproduced on several workstations in the company. 3) Burp proxy in response intercept mode ON correctly receives the HTML r...

  • Version burpsuite_pro_v1.7.15 (OSX) is crashing when trying to start

    While trying to start, the burp window opens but closes just after the screen refresh. It is strange because the JVM don't crash. The worst part is, I can not use the older version to reopen the project as now burps understand it was created for a newer version. Thanks

When copying the raw response into both classic Notepad and Notepad++ the raw response displays fine as HTML. Sending the response to the decoder also displays HTML - without using any of the encode or decode options. The proxy, intercept, i...

  • Cancelling a repeater request looses history

    In the repeater, if a request is timing out and it is cancelled then the history is lost, i.e. the arrows stop working and you can't see other requests. Done it for me a few times on current test so very repeatable.
