This module abuses a known default password on Micro Focus Operations Bridge Reporter.
The 'shrboadmin' user, installed by default by the product has the password of 'shrboadmin', and allows an attacker to login to server via SSH.
This module has been tested with Micro Focus Operations Bridge Manager 10.40. Earlier versions are most likely affected too, but have not been tested with this module.

Vuln details:

I believe you won't be able to test this unless you can get your hands on the vulnerable software, let me know if you require pcap and I'll send to you!

This all looks good to me, I tested the module as much as I could without a target and everything looks correct. Would you be able to send that PCap and then I can get this landed. When you do send the PCap can you include the text output too?

Thanks!

Nevermind, I see you already shared the PCaps. I took a look through there and yup, that's an SSH connection. Everything looks good here so I've landed the PR with just some minor changes to the documentation.

Thanks for this contribution!
