The log4j vulnerability is indeed very dangerous, but it can also be difficult to determine if you may be running a vulnerable version of log4j, because some software vendors rename the log4j package when they incorporate it into their software package. This can result in a "false negative" search result when using a CVE repository to look for vulnerabilities in a software component you have already installed and are running, that has been renamed i.e. ant-apache-log4j.jar

I highly recommend following the wise advice offered by CISA (link below) to mitigate this vulnerability ASAP.

Microsoft is also providing real-time updates regarding the log4j vulnerability with pointers to guidance to mitigate the vulnerability: https://msrc-blog.microsoft.com/2021/12/11/microsofts-response-to-cve-2021-44228-apache-log4j2/
