VMware NSX for vSphere (NSX-v) < 6.4.14 Multiple Vulnerabilities (VMSA-2022-0027)

critical Nessus Plugin ID 166697


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


The version of VMware NSX for vSphere (NSX-V) installed on the remote host is prior to 6.4.14. It is, therefore, affected by multiple vulnerabilities, including:

- VMware Cloud Foundation contains a remote code execution vulnerability via XStream open source library.
- VMware Cloud Foundation contains an XML External Entity (XXE) vulnerability. (CVE-2022-31678)

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.


Upgrade to VMware NSX for vSphere (NSX-V) 6.4.14 or later.
