"The version of edk2 / hvloader / openssl / nodejs18 installed on the remote CBL Mariner 2.0 host is prior to tested
version. It is, therefore, affected by a vulnerability as referenced in the CVE-2023-0465 advisory.

  - Applications that use a non-default option when verifying certificates May be vulnerable to an attack from
    a malicious CA to circumvent certain checks. Invalid certificate policies in leaf certificates are
    silently ignored by OpenSSL and other certificate policy checks are skipped for that certificate. A
    malicious CA could use this to deliberately assert invalid certificate policies in order to circumvent
    policy checking on the certificate altogether. Policy processing is disabled by default but can be enabled
    by passing the `-policy' argument to the command line utilities or by calling the
    `X509_VERIFY_PARAM_set1_policies()' function. (CVE-2023-0465)

Note that Nessus has not tested for this issue but has instead relied only on the application's self-reported version
number.");
