How do I remove KEX diffie-hellman-group1-sha1 from SSH on PAN-OS 8.1?

L1 Bithead

Our vulnerability scanner has detected a weak KEX algorithm (diffie-hellman-group1-sha1) on our firewall.  Is there a persistent way to disable the weak KEX algorithm?


I found this article (below), but it says every time the firewall reboots the weak algorithm becomes enabled again.

Hello friend, recently I had to apply 9.1.x and after the reboot the weak algorithms remained disabled.

That you comment most likely only applied to 8.x.x and 8.1.x.

Thanks for the reply.  I agree,  Unfortunately the latest version of PAN-OS compatible with the firewall in question is 8.1.x, so upgrading to 9.1.x is not an option for me.  I suppose I will have to deal with this until the HW is EOL and is replaced. I was just hoping there was "permanent" setting for 8.1.x.
