Error while running command openvas_connect: uninitialized constant OpenVASOMP::OMPConnectionError

[Isodoro]

Steps to reproduce

Sorry... me again! :-)

I might be being a muppet but I can't get Metasploit to connect to OpenVAS.
All the forum stuff I've searched for has been older versions etc.

This is a fresh 2024 build with spec as follows:

Linux kali 6.6.9-amd64 #1 SMP PREEMPT_DYNAMIC Kali 6.6.9-1kali1 (2024-01-08) x86_64 GNU/Linux
ruby 3.1.2p20 (2022-04-12 revision 4491bb740a) [x86_64-linux-gnu]
OpenVAS 22.7.9
gvm-libs 22.7.3

How'd you do it?

1. Latest build of Kali, Metasploit & OpenVAS installed
2. Loading msf and the openvas module (all good)
3. Using the openvas_connect however is failing

Were you following a specific guide/tutorial or reading documentation?

The OpenVAS build was followed from: https://www.kali.org/tools/gvm/
Both products work fine independently.

If yes link the guide/tutorial or documentation you were following here, otherwise you may omit this section.

Expected behavior

What should happen?

msf should connect to the OpenVAS app

Current behavior

What happens instead?

msf6 > load openvas
[*] Welcome to OpenVAS integration by kost and averagesecurityguy.

Now when I try to connect to 9392 with an admin account I created (tried admin as well) I get the following:

msf6 > **openvas_connect msfconsole msfconsole 127.0.0.1 9392 ok**

I think this PR here should resolve your issue if you wanted to give it a quick test
#18959

[Isodoro]

Hi,

Thanks for the response :-)

I manually edited my openvas.rb file with your line 189 change from #18959
The result as follows:

msf6 > openvas_connect msfconsole msfconsole 127.0.0.1 9392

ah, damn alright, thanks for dropping the stacktrace, was hoping I could get away without setting it up, I'll have a crack at fixing it when I get but feel free to throw up a PR if you wanna have a crack at fixing it yourself

[Isodoro]

no worries - I'm learning to code currently (very much a beginner)... this is all a bit new to me
I'm going to have a stab at working it out. If I manage to pull it off I'll post for sure. Don't hold your breath though! :-)

[dwelch-r7]

Ah ok so @Isodoro I did a little more digging and it looks like that's a pretty old unmaintained gem we're using https://rubygems.org/gems/openvas-omp

the issue seems to lie in the gem itself rather than in framework itself so I'm afraid getting this working would be more effort than I would have expected

[Isodoro]

Hi - Thanks for looking! Appreciated.

Completely understand - I tried a few things but nowhere near your level of expertise. I'd probably pull the "load openvas" option away from the next release btw.

Appears that the gvm-cli tools would be the way to move forward with this, however time consuming just for the sake of this automation.
REF: https://github.com/greenbone/gvm-tools

Quick question: Do you know if the Nessus integration works?

if you want to close this ticket off feel free :-)

[adfoster-r7]

I think this partial pull request was making things better for openvas, but there was some more fixes to make: #13944

Although it wasn't finished work, maybe that pull request would fix whatever issues are currently being hit

Edit: Also this thread: #13797
