Summary
VMWare Aria Operations for Networks (vRealize Network Insight) from version 6.0 to 6.10 did not regenerate the ssh keys for the support and ubuntu users, allowing an attacker with SSH access to gain root shell access to this product.
This issue was reported to VMWare by Harsh Jaiswal (@rootxharsh) and Rahul Maini (@iamnoooob) at ProjectDiscovery Research
I just wrote the exploit, if you can call it that, cause it's basically a ssh command wrapper.
