I just read about a severe security vulnerability in something called “log4j” from Apache. I have a LAMP droplet and I need to know how to find out if log4j is installed on the droplet? I don’t see a package by that name, but I’m not sure if I’m looking for the right thing.

Hi all,
In addition to what has already been mentioned, I could suggest taking a look at this answer here:

Hello, @JigsawBob
From what I can see Apache log4j 2 is an open-source Java-based logging framework that should not be installed by default on your Apache server, hence you’ve not manually installed/configured it then CVE-2021-44228 should not affect your server.
Regards, Alex
Hi JigsawBob, log4j is not installed as part of the standard LAMP stack. Unless you installed it yourself it is not on your server so you don’t need to do anything.
