  • TSL 1.2

    Hi All, thats my first post on Burp forum! :) I'm here for a noble cause I guess: trying to give TSL 1.2 support to the glorious (and mistreated) Windows XP. It seems infact the only way to do that, is to configure the system proxy, and Burp Proxy seems very good at that... ;) Unfortunately there is a problem: it all works only when HTTP/S Responses come within seconds. If the Response d...

  • Nested message editors

    Are there any artificial limitations regarding message editor nesting? By registering a message editor factory that creates instances of the class with the source code below, I expect it to act as as "proxy" and the resulting UI should be the same as with the original editor. This works fine if I just create it as a child of an ITab for example. However if I do this like below, invoking ...

Could the API be modified to allow ...

  • Collaborator: What are the exploitability differences between DNS lookups from different headers?

    Looking at the scan logs from Collaborator, I'm seeing medium severity for DNS lookups when the URL is supplied in either X-Forwarded-For or X-Wap-Profile, but red when it's caused by the Host header. I'm trying to understand why they are of different severity. In both instances, the server is performing a DNS request. Is it because the Host header isn't meant to be changed, so...

  • IBurpExtenderCallbacks.makeHttpRequest() throws RuntimeException

    If the network connection fails, callbacks.makeHttpRequest throws a RuntimeException. Any way we could get that method to declare that it throws a proper subclass of (presumably) IOException so we could check for and handle it in code?
