Thanks for this submission.
Can you please check for the following:

• VPN is disabled
• JDK 11 is installed
• You have burp professional v2020.4 or later

Note:
It's been tested with Burp Professional v2020.11.2

I am compiling a version of this plugin for all versions of burp professional very soon.

Please let me know how you go.

I will keep this report open until further notice.

Regards,
Blake

It seems your not running the latest version which may not resolve the issue but it's always good practise to keep up to date with the new version. 👍
Thanks

sorry ，i have install jdk 11.07 and burpsuite pro 2020.12.1,but when i scan the website (Basic SSRF against the local server), it still not work

Thanks for the response.

Try the following:

• Download the new build there should be a new one I upload today which is still version 1.12 but with a few bug fixes and changes.
• Try JDK 14
  Also, could you provide a screenshot & error that your getting so I can see?

Thanks so much!!

Hey @YumornZhang ,
Other people where facing the same problem that you had. So, I compiled this plugin with JDK 9 which should hopefully fix the compatibility issues.

I am keeping this issue open until further notice,
All the best! let me know how you go.

Regards,
Blake.

Hi @marz-hunter ,

It should work for all versions now, make sure to downloaded the latest one from the release page.

Let me know how you go :)

Blake

i downloaded the latest version, but i am using the old version of burp. and I heard that this tool will also be available on Bapp, I'll be waiting for it to install directly from Bapp

[ethicalhackingplayground]

Unfortunately at the moment it only works with burp 2020 pro. I will be working on this issue though 👍

I have the same problem，java version "1.8.0_311"，burpsuite professional v2.1。
Is there a solution!

Does it work for the burp pro 2021?
