log4j & cloud Confluence?

Timo Hilbertz December 13, 2021

hi, since the official statement about log4j is pretty brief (not to say lame), i'm looking for answers here. The vulnerability has been disclosed 4 days ago and still Confluence does not give any update. Anyone here who can help? Is the Confluence Data Center Cloud version vulnerable or not?

sorry, my bad: i mixed up the Confluence terminologies. I mean the Confluence Cloud version, not the Data Center version.

I checked our log4j version and it was 1.x  Since the vulnerability is in 2.x we are not affected.

Yes this is true. 

Yet what this means is that Atlassian needs to upgrade to log4j version2.16 ASAP. 

Version 1 is 2015. 



Also check if the org.apache.log4j.JMSAppender module is enabled, as per the articles posted by others. Then you are still vulnerable even with version 1(should not apply to cloud instances, only server/DC).

It depends on the version you have and version of the Log4j files you're using...check this site:
