I just received and email from Shopify that is about log4j vulnerability. and I am concerned about my other projects too most of them are built in PHP and have Ec2 server linux. How can I check if log4J is installed on my server or not, If installed then which version? as new version of log4j 2.15 has fixed this issue.
This is what I have done for now
Tried this command to check log4 logs
dpkg -l | grep log4
But I am not sure if that's enough or not. Is there any further precautions that I need to take to secure my server or not.
