VMware vCenter Server 6.5 / 6.7 Multiple Vulnerabilities (VMSA-2021-0027)

critical Nessus Plugin ID 155790

Synopsis

A virtualization management application installed on the remote host is affected by multiple vulnerabilities.

Description

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.

Solution

Upgrade to VMware vCenter Server 6.5 U3r, 6.7 U3p, or later.
