VMware vCenter Server < 7.0 U2d Multiple Vulnerabilities (VMSA-2021-0020)

medium Nessus Plugin ID 153546

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 prior to 7.0 U2d. It is, therefore, affected by multiple vulnerabilities:

- An unauthenticated API endpoint vulnerability exists in the vCenter Server Content Library. An unauthenticated, remote attacker can exploit this to perform unauthenticated VM network setting manipulation. (CVE-2021-22011)

- A file deletion vulnerability exists in the VMware vSphere Life-cycle Manager plug-in. A unauthenticated, remote attacker can exploit this to delete non-critical files. (CVE-2021-22018)

Note that Nessus has not tested for this issue 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 7.0 U2d or later or apply the workaround mentioned in the advisory.
