"The version of VMware vCenter Server installed on the remote host is 6.5 prior to 6.5 U3r or 6.7 prior to 6.7 U3p. It
is, therefore, affected by multiple vulnerabilities:

  - An arbitrary file read vulnerability exists in the vSphere web client. An unauthenticated, remote attacker
    can exploit this, via HTTPS, to gain access to sensitive information. (CVE-2021-21980)

  - A server side request forgery vulnerability exists in the vSAN Web Client plug-in. An unauthenticated,
    remote attacker can exploit this, via HTTPS, to cause the server to access internal services or access
    sites outside of vCenter. (CVE-2021-22049)

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version   
number. Nessus has also not tested for the presence of a workaround.");
