I have a vulnerability scanner that has flagged a specific log4j file on my deployed instance of SQL 2019 as being out of date - it's log4j-1.2.17.jar 1.2.17, and there's an update called 2.17 but there's no installer for it - just random files. The developer's site only seems to have guidance on how to do integrations for developers, not on already deployed applications. Has Microsoft released guidance on how to update Apache / Log4j on MS SQL 2019 instances?
Hi,
I have a vulnerability scanner that has flagged a specific log4j file on my deployed instance of SQL 2019 as being out of date
This is a know issue. It is recommended to get more information from the apache site first:
https://logging.apache.org/log4j/2.x/
Has Microsoft released guidance on how to update Apache / Log4j on MS SQL 2019 instances?
Yes. Microsoft release information on the issue but update the Log4j is not related to Microsoft directly but to Apache.
I highly recommend you to go over the following Microsoft documents regarding the issue
https://msrc-blog.microsoft.com/2021/12/11/microsofts-response-to-cve-2021-44228-apache-log4j2/
Hi ME-6236,
In addition, Microsoft is currently evaluating the presence of older versions of log4j shipped with some of the product components. While these files are not impacted by the vulnerabilities in CVE-2021-44228 or CVE-2021-4104, the respective engineering teams are assessing their use of these files to determine their long-term plans to address the end of life for Log4J 1.2.
Best Regards,
Amelia

@AmeliaGu-msft is there any update to Log4j 1.2 removal/update in SQL Server 2019 installations?
If you don't have the source code of a project and just want to fix the log4j 1.x vulnerabilities you can use reload4j project. It allows to replace the file log4j-1.2.17.jar by the reload4j jar file without other changes.
The reload4j project is a fork of Apache log4j version 1.2.17 in order to fix most pressing security issues. It is intended as a drop-in replacement for log4j version 1.2.17. By drop-in, we mean the replacement of log4j.jar with reload4j.jar in your build without needing to make changes to source code, i.e. to your java files.
Microsoft released CU16 that includes this log4j resolution.
Removes log4j2 used by SQL Server 2019 Integration Services (SSIS) to avoid any potential security issues.
