Update on Statement on “Log4j” Vulnerability


December 20, 2021 Updates:

A new zero-day vulnerability (CVE-2021-45105) (Apache Log4j2 - does not always protect from infinite recursion in lookup evaluation) was reported by Apache for the Apache Log4j component on December 18, 2021. Micro Focus is taking immediate action to analyse and to remediate where appropriate. The reported vulnerability (CVE-2021-45105 / Apache Log4j2) is in the Apache Log4j open source-component that allows Remote Code Execution. This enables an attacker with control over Thread Context Map data to cause a denial of service when a crafted string is interpreted. This is defined by the Common Vulnerability Scoring System(CVSS) as a level 7.5 exploit. Micro Focus uses Log4j for standard logging functionality across a number of product portfolios. We are actively remediating the vulnerability across those products to protect both SaaS and on-premises customers and issuing security bulletins with instructions on how to remediate for on-premises installations. We will continue to provide details of the Log4j compromise until the risk is completely mitigated.

After investigation and analysis, we have had no indications of Log4j intrusions to date.
