The ESXi host rhttpproxy daemon must use FIPS 140-2 validated cryptographic modules to protect the confidentiality of remote access sessions.


Overview

Finding ID Version Rule ID IA Controls Severity
V-256442 ESXI-70-000090 SV-256442r886107_rule Medium
Description
ESXi runs a reverse proxy service called rhttpproxy that front ends internal services and application programming interfaces (APIs) over one HTTPS port by redirecting virtual paths to localhost ports. This proxy implements a FIPS 140-2 validated OpenSSL cryptographic module that is in FIPS mode by default. This configuration must be validated and maintained to protect the traffic that rhttpproxy manages.

Check Text ( C-60117r886105_chk )
From an ESXi shell, run the following command:

# esxcli system security fips140 rhttpproxy get

or

From a PowerCLI command prompt while connected to the ESXi host, run the following commands:

$esxcli = Get-EsxCli -v2
$esxcli.system.security.fips140.rhttpproxy.get.invoke()

Expected result:

Enabled: true

If the output does not match the expected result, this is a finding.
Fix Text (F-60060r886106_fix)
From an ESXi shell, run the following command:

# esxcli system security fips140 rhttpproxy set -e true

or

From a PowerCLI command prompt while connected to the ESXi host, run the following commands:

$esxcli = Get-EsxCli -v2
$arguments = $esxcli.system.security.fips140.rhttpproxy.set.CreateArgs()
$arguments.enable = $true
$esxcli.system.security.fips140.rhttpproxy.set.Invoke($arguments)
