vRealize Suite Lifecycle Manager 8.x leverages Log4j in its server and blackstone spring jar’s, and so with the recent vulnerability noted in CVE-2021-44228 - VMSA-2021-0028 we need to patch the affected files.

root@vrslcm [ /tmp ]# ls -lah log4jfix.sh -rwx------ 1 root root 339 Dec 12 19:29 /tmp/log4jfix.sh
root@vrslcm [ /tmp/ ]# ./log4jfix.sh
