Hello @bobby dammu

Can you please provide some context on "public facing settings"? What exactly are you trying to do/not do?

Thank you so much for the quick response.

Description:

Due to a security concern regarding 'log4j', we are looking options to mitigate risk. One option is re-configure the Bamboo server (and agents) to no longer be publicly accessible.

Thanks,

Bobby

Hello @bobby dammu,

Thanks for clarifying that.

Bamboo is not vulnerable to the recent Log4j CVEs. You can find more details below:

• FAQ for CVE-2021-44228, CVE-2021-45046 and CVE-2021-45105
• Multiple Products Security Advisory - Log4j Vulnerable To Remote Code Execution - CVE-2021-44228 

Though, if you still want to disable any "public" access to your Bamboo Server and Agents, you'll have to work with your external configurations such as blocking traffic on our Firewall, Load Balancer, etc.

Bamboo needs to listen to specific ports to work. There is no option to disable such services.

You can also create local firewall rules on each server that is part of your Bamboo solution to allow only trusted sources to reach its service ports:

• Ports used by Atlassian Applications - Bamboo

You can also enable Tomcat's Client authentication to enforce only validated clients
