Hi Sham,

Your vulnerability scan flagged iLO Amplifier Pack  version 2.23 build 1 for CVE-2023-38408, related to OpenSSH 7.9p1, which has a remote code execution  risk via forwarded ssh-agent.

- You are already on the latest version (2.23), but HPE may release a future update addressing this vulnerability.

- If possible disable SSh 

- If disabling SSH isn’t possible, configure your firewall to block incoming connections on port 22.

- Since this is the latest version, reach out to HPE Support for confirmation on whether a fix is planned. 

By applying these steps, you can reduce exposure to the vulnerability while waiting for an official patch.

Let me know how it goes.

Hello,

Thnank you for going back to me.

I am happy to disable SSH - can you advise if this is possible on iLO Amplifier appliance as I haven't seen this option in the web interface?

If this is not possible I will try to block it on the firewall.

I will try opening a case with HPE support as well.

Thank you.

@ShamVMH 

Disabling SSH on the iLO Amplifier Pack is a prudent step to mitigate the CVE-2023-38408 vulnerability. However, as you've noted, the web interface does not provide an option to disable SSH. Additionally, the available user guides do not offer specific instructions for this action.

Since disabling SSH directly on the iLO Amplifier Pack isn't feasible through the web interface, you can configure your network firewall to block incoming connections on port 22, which is used for SSH. This approach effectively prevents SSH access to the appliance.

If not, please go ahead and log a support case, they will help further.
