VMware vCenter Server 6.5 / 6.7 / 7.0 DoS (VMSA-2020-0018)

medium Nessus Plugin ID 140040

Language:

Synopsis

A virtualization management application installed on the remote host is affected by a denial of service vulnerability.

Description

The version of VMware vCenter Server installed on the remote host is 6.5 prior to 6.5u3k, 6.7 prior to 6.7u3j or 7.0 prior to 7.0.0b. It is, therefore, affected by a denial of service vulnerability (DoS) in the authentication service. An unauthenticated, remote attacker can exploit this issue to exhaust memory resources resulting in a degradation of performance condition while the attack is sustained.

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

Solution

Upgrade to VMware vCenter Server 6.5u3k, 6.7u3j, 7.0.0b or later.
