Hi,

In burp I get an error like "Failed to connect to 127.0.0.1:8888"

the server is not started obviously.

Also, when I unload the extension I get an error like

java.lang.ExceptionInInitializerError: Exception java.lang.UnsatisfiedLinkError: Unable to load library 'server.so':

I've managed to start the server, but it doesn't work.

I'm detected and get a message like:

<html><head><title>Request Rejected</title></head><body>The requested URL was rejected. Please consult with your administrator.<br><br>Your support ID is: 16672172601756045050<br><br><a href='javascript:history.back();'>[Go Back]</a></body></html>

Please provide more details.

  • How did you manage to solve your initial issue and start the server?
  • What site are you trying to access?

Sure,

I pointed the Java Enviroment in Burp to the location where I compiled the server.so file.

I can't provide the website in public, but I can say that it is hosting in Azure, so it's not technically Cloudflare or Akamai. Also I can load the homepage and after I try to login I get detected and get that error.

About your initial issue: did you download Burp-Awesome-TLS-linux-amd64.jar or Burp-Awesome-TLS-fat.jar from the latest release? Only those builds contain the linux-x86-64/server.so library you need for your OS and architecture.

And regarding this misterious site that doesn't work on your end, I'll need more details. You can send me a message on Telegram or Discord if you're willing to share the URL in private, otherwise it will be impossible for me to look into it. Either way it's unrelated to this issue.

@sleeyax ,

It's not just about sharing the URL, I'll need to share the credentials as well and I can't do that (it's a client).

the homepage loads fine, but when I try to login and do a POST that is when I'm detected and blocked.

thanks.

Understandable, but without a reproducible example for me to test you're on your own. You can build this project from source, enable debugging and compare HTTP/TLS requests with real browser traffic to try and see where it goes wrong. Closing this issue because it's going off topic.
