Is CertMaster Impacted by the Apache Log4j vulnerability (CVE-2021-44228)

CertMaster online learning platform is not impacted by the Apache Log4j vulnerability (CVE-2021-44228), as we do not use Java or Log4j in any of the CertMaster systems/services (the CertMaster backend server is written in Microsoft’s .NET Core framework). Our web-based shopping cart at https://shop.testout.com is also not impacted.
