Two high severity vulnerabilities, (CVE-2021-44228 and CVE-2021-45046), impacting multiple versions of Apache Log4j utility, were disclosed recently. We have found no evidence of any exploitation in ADManager Plus as of now.


However, as the affected Log4j version is used in ADManager Plus in the bundled dependency, we strongly recommend all our customers to follow the below steps to protect ADManager Plus from the vulnerabilities.




1. This procedure is applicable for both vulnerabilities (CVE-2021-44228 and CVE-2021-45046) irrespective of ADManager Plus' current build number.
