Location Risk Intelligence

All systems scanned. A 3rd party component contained a log4j library, however there was no known exploit available at any time for this component. A Log4Shell mitigation patch was applied immediately as announced by the 3rd party. The scripts removed the JndiLookup class which is the only mitigation measure recommended by Apache Log4j that does not require updating the Log4j version. This action fully addresses CVE-2021-44228 and CVE-2021-45046.
