Metalogix Essentials is an on-premises product which is installed within the protected perimeter of the customer’s environment.

As such the exploitability of these vulnerabilities is more limited and consequently the overall risk to the customer environment or data is lower than the published severity of CVE-2021-44228, CVE-2021-45046 and CVE-2021-45105.

Metalogix Essentials 2.7 and 2.8 are not affected by CVE-2021-44228, CVE-2021-45046 and CVE-2021-45105 as these versions ship with Log4j version 1.x with no JMSAppender extension.
